Description
Technical Field
[0001] This invention relates to the field of blasting data processing, and more specifically, to a method for recommending parameters for smooth blasting of fractured rock masses. Background Technology
[0002] Smooth blasting of fractured rock masses is commonly used for slope excavation and shaping control. During construction, blasting parameters need to be determined based on the slope design profile, borehole layout, borehole spacing, borehole inclination angle, borehole depth, charge structure, filling condition, and the degree of rock fragmentation at the site. In actual construction, borehole location, spacing, inclination angle, filling condition, and charge structure can deviate due to rock mass structure, equipment positioning errors, borehole wall fragmentation, and on-site adjustments. After blasting, slope smoothness, over-excavation / under-excavation, half-hole ratio, and evaluation status can reflect the quality of blasting shaping; however, these data are often stored separately in design records, construction records, and post-blast inspection records, lacking unified organization within the same borehole segment relationship.
[0003] Existing methods for determining blasting parameters largely rely on pre-blast experience-based design, geological condition analysis, or adjustments to parameters during a single blast. Parameters such as hole spacing, charge quantity, and filler length are typically determined based on engineering experience, surrounding rock conditions, and the design cross-section. While some intelligent design methods can provide parameter combinations based on site conditions, and some post-blast testing methods can evaluate slope formation quality, a stable correlation does not exist between design parameters, actual construction data, and post-blast formation evaluation data. For smooth blasting in fractured rock masses, knowing only whether the post-blast evaluation is satisfactory or unsatisfactory is insufficient to determine whether the change in evaluation status stems from variations in hole spacing, borehole inclination angle, charge structure, or filler condition.
[0004] Within the same construction section, construction deviations at different borehole positions have varying impacts on the final formation results. Increased borehole spacing at certain positions may still correspond to acceptable records, while decreased spacing at adjacent positions may simultaneously result in unacceptable records. Furthermore, changes in charge structure or packing configuration may only cause changes in the formation evaluation at localized sections. Treating an entire construction section as a single sample, or relying solely on the average parameters of that section for recommendations, can easily lead to the mixing of sample records from different deviation types, resulting in a lack of clear evidence of the source of deviation in the parameter recommendations for the section to be recommended.
[0005] Therefore, a data processing method for smooth blasting in fractured rock masses is needed. This method unifies blasting design data, actual construction data, and post-blast shaping evaluation data into a sample record according to the slope design outline and borehole segment relationship. It identifies the deviations and directions of change between the actual construction data and the blasting design data, and combines this with the evaluation state transitions of the post-blast shaping evaluation data to form deviation influence rules. By selecting similar samples that are evaluated as qualified under the same deviation type, and generating a recommendation verification result after the blasting of the recommended construction section, the recommended parameters can maintain the same data caliber as the actual field execution results.
[0006] To address the aforementioned problems, a technical solution is provided. Summary of the Invention
[0007] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a method for recommending parameters for smooth blasting in fractured rock masses. This method involves receiving blasting design data, actual construction data, and post-blasting shaping evaluation data from completed construction sections. The sequence of borehole positions is determined according to the slope design contour. The post-blasting shaping evaluation data is then categorized into sample records based on the projected overlap length. The blasting design data and actual construction data are aligned, and the deviation content and direction of change for parameters of the same numerical type are calculated to form construction deviation data. Based on adjacent change directions and evaluation state transitions, splitting boundaries, mutually exclusive subsets, and continuous deviation types are determined to obtain deviation influence rules. The initial field data of the construction section to be recommended is matched with the deviation influence rules, and similar samples evaluated as qualified under the same deviation type are selected to generate parameter recommendation results. After blasting, a recommendation verification result is generated to update the deviation influence rules, thereby solving the problems mentioned in the background art.
[0008] To achieve the above objectives, the present invention provides the following technical solution: Receive blasting design data, construction measurement data and post-blast forming evaluation data, determine the sequence of borehole segment relationships according to the slope design outline, and assign the post-blast forming evaluation data according to the projected overlap length to obtain sample records; Align the blasting design data and the actual construction measurement data, calculate the deviation content and direction of change of the same numerical parameter, and obtain the construction deviation data; By comparing the adjacent change directions of the same numerical parameter in the construction deviation data along the sequence of borehole segment relationships, when adjacent change directions are opposite and the same adjacent borehole segment relationship undergoes an evaluation state transition, the same adjacent borehole segment relationship is used as the split boundary to form a mutually exclusive subset; when adjacent change directions are not simultaneously opposite and the evaluation state transition is not satisfied, a continuous deviation type is formed, and the deviation influence rule is obtained. Obtain the initial on-site data of the construction section to be recommended, filter similar samples that are rated as qualified under the same deviation type according to the deviation influence rule, and generate parameter recommendation results based on the deviation content of similar samples; After the blasting of the section to be recommended, the measured construction data and post-blast forming evaluation data of the section to be recommended are fed back to the parameter recommendation results to obtain the recommendation verification results. If there is an adjacent blast hole segment relationship that simultaneously satisfies the opposite direction of change and the evaluation state transition, the split boundary and deviation influence rules are updated; if there is no adjacent blast hole segment relationship that simultaneously satisfies the opposite direction of change and the evaluation state transition, the update is stopped.
[0009] Furthermore, determining the sequence of borehole positions based on the slope design profile includes: Read the center position of the borehole projection on the slope design profile for each borehole; For borehole segments in the middle sequence, the midpoint between the projection center of the previous borehole and the projection center of this borehole is taken as the starting position, and the midpoint between the projection center of this borehole and the projection center of the next borehole is taken as the ending position. For the positional relationship of the first and last borehole segments, the corresponding projection intervals are closed by the starting point and ending point of the completed construction segment on the slope design outline.
[0010] Furthermore, the post-explosion shaping evaluation data assigned according to the projected overlap length includes: The detection range of the post-explosion forming evaluation data is projected onto the slope design profile along a direction perpendicular to the slope design profile to obtain the projection start position and projection end position. When the detection range covers a borehole segment relationship, the post-blast formation evaluation data will be included in the covered borehole segment relationship. When the detection range covers multiple borehole segment relationships, the post-blast formation evaluation data will be assigned to the borehole segment relationship with the largest projection overlap length. When the projection overlap lengths are the same, the affiliation is determined according to the location of the detection center. If the detection center location falls on the dividing position, it is assigned to the blast hole segment relationship that is ranked earlier.
[0011] Furthermore, the evaluation state during the evaluation state transition is formed in the following way: When the post-explosion molding evaluation data includes the acceptance conclusion, the acceptance conclusion will be written into the evaluation status. When the post-blast forming evaluation data includes test values, the evaluation standards are read from the forming quality requirements in the blasting design data, the acceptance records of the completed construction sections, and the construction acceptance documents. Test values that meet the evaluation standards are written into the qualified record, and test values that do not meet the evaluation standards are written into the unqualified record. When the evaluation criteria cannot be read, the evaluation status will be recorded as an empty field; When there are multiple post-blast formation evaluation data for the same borehole segment relationship, if there is an unqualified record, the evaluation status will be recorded as an unqualified record; if there is no unqualified record and there is a qualified record, the evaluation status will be recorded as a qualified record.
[0012] Furthermore, the alignment of blasting design data and actual construction measurement data includes: For the same borehole section relationship, first establish the parameter correspondence between the design parameters and the actual construction parameters on site according to the parameter names; When parameter names are inconsistent, a parameter correspondence relationship shall be established according to the relationship of the borehole section, the unit of measurement and the purpose of the parameter. If the three are consistent, they shall be identified as the corresponding design parameters and actual on-site construction parameters. If any one of them is inconsistent, no parameter correspondence relationship shall be established. When the blasting design data contains design parameters but the actual construction measurement data does not contain corresponding on-site construction parameters, mark the missing measurement content in the construction deviation data; When the actual construction parameters exist in the measured construction data but the corresponding design parameters do not exist in the blasting design data, the newly added construction content is marked in the construction deviation data.
[0013] Furthermore, similar samples are determined in the following way: When the number of borehole segment relationships between the construction section to be recommended and the completed construction section to which the sample record belongs is the same, the sequence distance is determined according to the number of intervals between their arrangement order in their respective construction sections, and the sample record with the smallest sequence distance and the post-blast forming evaluation data is a qualified record is determined as a similar sample. When the number of borehole segment relationships in the construction section to be recommended and the completed construction section to which the sample record belongs are different, the order ratio of borehole segment relationships in the construction section to be recommended and the order ratio of borehole segment relationships in the sample record are obtained respectively, and the sample record with the smallest difference in order ratio and the post-blast forming evaluation data is qualified is determined as a similar sample. When using sequential distance to determine similar samples and the sequential distances are the same, first select the sample record whose change direction is consistent with the initial deviation content. If there are still multiple sample records, select the sample record that is written first in the order. When using sequential ratio difference to determine similar samples and the sequential ratio difference is the same, first select the sample record whose change direction is consistent with the initial deviation content. If there are still multiple sample records, select the sample record that is written first in the order.
[0014] Furthermore, the replacement parameters in the parameter recommendation results are formed in the following way: Replacement parameters do not generate a dominant deviation type separately; When the sample record range for numerical parameters has been determined under the same borehole segment relationship, the sample record of the post-blast formation evaluation data that is qualified is read from the sample record range, and the similar sample is determined according to the similar sample determination method. When no numerical parameter sample record range is formed under the same borehole segment relationship, similar samples are determined from the sample records of qualified post-blasting formation evaluation data of the same construction section in the blasting sample library. When no qualified record exists, the parameter recommendation result retains the design parameter field content from the initial site data.
[0015] Furthermore, the sample records are written into the borehole segment relationship field, blasting design data field, construction measured data field, and post-blast forming evaluation data field; Construction deviation data is written into the numerical parameter name, design parameter, actual on-site construction parameter, deviation content, direction of change, and replacement relationship; The deviation impact rules are written into the numerical parameter name, borehole segment relationship, change direction, evaluation state transition, split boundary, mutual exclusion subset affiliation, and continuous deviation type.
[0016] Furthermore, the parameter recommendation results are written into the borehole segment relationship, numerical parameter name, recommended value, replacement parameter name, recommended content, similar sample source and unmatched status; It is recommended that the verification results be written into the borehole segment relationship, numerical parameter name, deviation content, change direction, replacement relationship and post-blast formation evaluation data; When the post-blast formation evaluation data field in the recommended verification results is empty, the corresponding borehole segment relationship will not be included in the evaluation state transition judgment.
[0017] Furthermore, the rules for updating split boundaries and bias effects include: Before redefining mutually exclusive subsets, the recommendation verification results of the construction sections to be recommended are converted into new sample records; New sample records are written in the order of borehole segment relationship, and the blasting design data, construction measurement data, post-blast forming evaluation data, deviation content, change direction and replacement relationship of the construction segment to be recommended are saved; Newly added sample records, together with existing sample records in the blasting sample library, participate in the mutual exclusion subset partitioning after translation. Regardless of whether the deviation affects the rule to complete the update or stop updating, the newly added sample records are written into the blasting sample library.
[0018] The technical effects and advantages of the method for recommending parameters for smooth blasting of fractured rock mass according to the present invention are as follows: This invention unifies blasting design data, actual construction measurement data, and post-blasting shaping evaluation data under the same borehole segment relationship for processing. This ensures that data originally scattered across design records, construction records, and post-blasting inspection records have a consistent comparison standard, clearly identifying the deviations and directions of changes in actual construction parameters relative to design parameters, reducing misjudgments caused by judging parameter quality solely based on the overall results of a construction segment. By using the positions of adjacent changes with opposite directions and the evaluation state transition positions as the split boundary, this invention fixes the correspondence between local construction deviations and slope shaping evaluation as a deviation influence rule, avoiding the mixing of sample records under different deviation types for parameter recommendation. When recommending construction segments, deviations are extracted only from similar samples evaluated as qualified under the same deviation type to generate parameter recommendation results, ensuring that the recommendation results have actual measurement evidence from completed construction segments. After the recommended construction section is blasted, the actual construction data and post-blast shaping evaluation data can be reflected back to the parameter recommendation results and form the recommendation verification results. This allows the deviation influence rules to be updated or stopped based on the actual execution results, thereby improving the data consistency, evaluation stability and result traceability of the parameter recommendation process for smooth blasting of fractured rock mass.

Detailed Implementation
[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Please see Figure 1 - Figure 5 This invention provides a method for recommending parameters for smooth blasting of fractured rock mass, comprising: S1: Receive blasting design data, actual construction measurement data and post-blast forming evaluation data, determine the sequence of borehole segment relationships according to the slope design outline, and assign the post-blast forming evaluation data according to the projected overlap length to obtain sample records; S2: Align the blasting design data and the actual construction measurement data, calculate the deviation content and direction of change of the same numerical parameter, and obtain the construction deviation data; S3: Compare the adjacent change directions of the same numerical parameter in the construction deviation data along the sequence of borehole segment relationships. When the adjacent change directions are opposite and the same adjacent borehole segment relationship undergoes an evaluation state transition, the same adjacent borehole segment relationship is used as the split boundary to form a mutually exclusive subset; when the adjacent change directions are not opposite and the evaluation state transition is not satisfied at the same time, a continuous deviation type is formed, and the deviation influence rule is obtained. S4: Obtain the initial on-site data of the construction section to be recommended, filter similar samples that are evaluated as qualified under the same deviation type according to the deviation influence rule, and generate parameter recommendation results based on the deviation content of the similar samples; S5: After blasting the section to be recommended, the actual construction data and post-blast forming evaluation data of the section to be recommended are fed back to the parameter recommendation results to obtain the recommendation verification results. If there is an adjacent blast hole segment relationship that simultaneously satisfies the opposite direction of change and the evaluation state transition, the split boundary and deviation influence rules are updated; if there is no adjacent blast hole segment relationship that simultaneously satisfies the opposite direction of change and the evaluation state transition, the update is stopped.
[0022] This invention focuses on data processing for completed and recommended construction sections. For completed sections, the sequence of borehole positions is first established according to the slope design outline. Blasting design data, actual construction data, and post-blasting shaping evaluation data are written into a sample record with the same aperture. Then, the blasting design data and actual construction data are compared under the same borehole position relationship to obtain construction deviation data including deviation content, direction of change, and replacement relationship. Subsequently, adjacent change directions are compared along the borehole position relationship, and combined with evaluation state transitions to form split boundaries, mutually exclusive subsets, and continuous deviation types, resulting in deviation influence rules. For recommended construction sections, the initial field data is organized into an expression consistent with the construction deviation data. Based on the deviation influence rules, similar samples evaluated as qualified under the same deviation type are selected to generate parameter recommendation results. After blasting is completed in the recommended construction section, the actual construction data and post-blasting shaping evaluation data are reflected back to the parameter recommendation results to form recommendation verification results. Based on this, the split boundaries and deviation influence rules are updated or updates are stopped.
[0023] Detailed implementation of step S1: Step S1 is used to collect and process multi-source data within the completed construction section. The input data includes blasting design data, construction measurement data, and post-blast forming evaluation data. The processing goal is to include the design content, construction content, and post-blast evaluation content under the same borehole segment relationship into the same sample record. However, post-blast forming evaluation data often comes from slope forming inspection, and the inspection range may span adjacent borehole segment relationships. Therefore, it is necessary to first determine the order of borehole segment relationships and then determine the unique location of the post-blast forming evaluation data.
[0024] S101. Establish the sequence of borehole segment relationships: The borehole segment relationship is used to represent the arrangement and adjacent relationships of each borehole along the slope design outline within the completed construction section. After receiving the completed construction section, the borehole layout content in the blasting design data is read first, and the field borehole records in the construction measurement data are read. The records of the same borehole in the blasting design data and the construction measurement data are mapped to the same borehole segment relationship.
[0025] The slope design profile is obtained from the slope profile design drawing, surveying and setting-out data, or construction design documents in the blasting design data. The starting and ending positions of each borehole segment relationship are obtained from the two ends of the projection interval of the borehole segment relationship on the slope design profile, so that the sequence of borehole segment relationships has a clear data source.
[0026] When determining the projection range of borehole positions on the slope design profile, first read the center position of the borehole projection on the slope design profile for each borehole. For borehole positions in the middle sequence, the midpoint between the center position of the previous borehole projection and the center position of this borehole projection is taken as the starting position, and the midpoint between the center position of this borehole projection and the center position of the next borehole projection is taken as the ending position. For borehole positions at the beginning, the starting point of the completed construction section on the slope design profile is taken as the starting position, and the midpoint between the center position of the first borehole projection and the center position of the next borehole projection is taken as the ending position. For borehole positions at the end, the midpoint between the center position of the previous borehole projection and the center position of the last borehole projection is taken as the starting position, and the end point of the completed construction section on the slope design profile is taken as the ending position.
[0027] The sequence of borehole positions is based on the slope design profile. Specifically, the starting and ending positions of each borehole position are determined along the slope design profile, and then arranged in ascending order of starting position. Borehole positions with earlier starting positions are listed first, and those with later starting positions are listed later. If two borehole positions have the same starting position, they are arranged in ascending order of ending position. After sorting, the sequence of borehole positions within the same construction section is obtained.
[0028] After the sequence of borehole segment relationships is determined, the content corresponding to a specific borehole segment relationship in the blasting design data is written into the design field of the same borehole segment relationship, and the content corresponding to the same borehole segment relationship in the construction measurement data is written into the construction field of the same borehole segment relationship. The design field is used to store the parameter content formed during the design phase, and the construction field is used to store the measured content after field execution. At this point, the blasting design data and the construction measurement data have the same arrangement caliber.
[0029] S102. Determine the unique ownership of post-explosion forming evaluation data: Post-blast formation evaluation data comes from post-blast inspections. The inspection range may fall within a single borehole segment relationship or cover the area between adjacent borehole segment relationships. To avoid the same post-blast formation evaluation data being repeatedly written into adjacent sample records, the inspection range of the post-blast formation evaluation data is first projected onto the slope design outline, and then the projected inspection range is compared one by one with the sorted borehole segment relationships.
[0030] To clarify the method for obtaining the projection coincidence length, the detection range of the post-blast forming evaluation data is projected onto the slope design profile along a direction perpendicular to the slope design profile, obtaining the starting and ending positions of the projection of the detection range onto the slope design profile; the two ends of the projection interval of the borehole segment relationship on the slope design profile are respectively used as the starting and ending positions of the corresponding borehole segment relationship. The projection coincidence length is calculated according to the following formula: ; in, Indicates the first Post-explosion molding evaluation data and the first The overlapping length of the projection of the segment relationship of each blast hole on the slope design profile; Indicates the first The starting position of the projection of the post-explosion molding evaluation data; Indicates the first The projection termination position of the post-explosion molding evaluation data; Indicates the first The starting position of the projection of the relationship between the segments of each borehole; Indicates the first The projection termination position of the segment relationship of each blast hole; the above positions are all obtained by the mileage position or projection position on the slope design profile, and both sides of the formula are in the dimension of length.
[0031] When the detection range of post-blast forming evaluation data only covers one borehole segment relationship, the post-blast forming evaluation data is assigned to the covered borehole segment relationship. When the detection range of post-blast forming evaluation data covers multiple borehole segment relationships, the overlap length between the detection range and each borehole segment relationship on the slope design profile is calculated. The overlap length is the length of the portion jointly occupied by both on the slope design profile. After comparing the overlap lengths, the post-blast forming evaluation data is assigned to the borehole segment relationship with the largest overlap length.
[0032] When two adjacent borehole segments have the same overlap length, the detection center position of the post-blast forming evaluation data is read. The post-blast forming evaluation data is assigned to the borehole segment relationship in which the detection center position is located. When the detection center position falls exactly at the boundary between two borehole segments, the post-blast forming evaluation data is assigned to the borehole segment relationship that is listed first in the sequence of borehole segments. When the detection range of the post-blast forming evaluation data has no overlap length with any borehole segment relationship within the completed construction section, the post-blast forming evaluation data is not written into the sample record of this completed construction section, and the original detection position is retained.
[0033] For example, a completed construction section has three borehole positions along the slope design outline. The first borehole position covers the 0-2 meter range on the slope design outline, the second covers the 2-4 meter range, and the third covers the 4-6 meter range. A post-blast formation evaluation data point, projected onto the slope design outline, covers a range of 1.5-3.2 meters. Its overlap with the first borehole position is 0.5 meters, with the second borehole position is 1.2 meters, and it does not overlap with the third borehole position. After comparison, the post-blast formation evaluation data is assigned to the second borehole position; the first and third borehole positions are not included in the same post-blast formation evaluation data.
[0034] S103. Form a sample record arranged according to the relationship of borehole segments: After uniquely assigning the post-blast formation evaluation data, sample records are established according to the borehole segment relationship. Each sample record corresponds to a borehole segment relationship and includes four fixed fields: borehole segment relationship, blasting design data, construction measurement data, and post-blast formation evaluation data. The borehole segment relationship field records the arrangement position of this sample record in the completed construction section; the blasting design data field records the design content corresponding to this borehole segment relationship; the construction measurement data field records the on-site execution content corresponding to this borehole segment relationship; and the post-blast formation evaluation data field records the post-blast inspection content written into this borehole segment relationship through the unique assignment rule.
[0035] For borehole segment relationships that have been assigned post-blast formation evaluation data, the corresponding post-blast formation evaluation data is written into the post-blast formation evaluation data field. For borehole segment relationships that have not been assigned post-blast formation evaluation data, the post-blast formation evaluation data field is left empty. An empty field only indicates that no post-blast formation evaluation data has been obtained for this borehole segment relationship; it does not change the content written to the blasting design data field and the construction measured data field. All sample records are written into the blasting sample library in the order of borehole segment relationships, resulting in sample records arranged by borehole segment relationships.
[0036] When writing data to the blasting sample library, a write status check is performed on each piece of post-blast formation evaluation data. Post-blast formation evaluation data already written for a specific borehole segment relationship will not be written for other borehole segment relationships. If the same borehole segment relationship corresponds to multiple post-blast formation evaluation data, these multiple post-blast formation evaluation data are sorted according to the starting position of the detection range on the slope design outline and then written into the same post-blast formation evaluation data field. Through this process, the sample records in the blasting sample library maintain the arrangement order of borehole segment relationships while avoiding the same post-blast formation evaluation data being repeatedly entered into multiple sample records.
[0037] After step S1 is completed, the blasting sample library forms sample records arranged according to the borehole segment relationship. Each sample record corresponds to a unique borehole segment relationship and stores blasting design data, construction measurement data and uniquely assigned post-blast formation evaluation data in the same data structure, so that step S2 can align the blasting design data and construction measurement data within the same borehole segment relationship.
[0038] Detailed implementation of step S2: Step S1 has already aligned the blasting design data, actual construction data, and post-blast shaping evaluation data into the same borehole segment relationship. Step S2 reads the blasting design data and actual construction data from the same borehole segment relationship. The goal is to compare the design parameters with the actual construction parameters on site under the same slope design profile benchmark. However, different parameters are expressed in different ways. Numerical parameters can be used to calculate deviations, while charge structure and filling status need to be recorded as replacement relationships. Therefore, step S2 first classifies the parameters, then performs deviation calculations and writes the data.
[0039] S201. Extract the design parameters and actual on-site construction parameters for the same borehole segment relationship from the sample records: Read the sample records generated in step S1, maintaining the order of borehole segment relationships within the sample records. Each sample record corresponds to a borehole segment relationship. The blasting design data field stores design parameters, while the actual construction measurement data field stores on-site construction parameters. For the same borehole segment relationship, first read the design parameters from the blasting design data item by item, then search for the actual on-site construction parameters corresponding to the name and engineering meaning in the construction measurement data, forming the parameter correspondence under the same borehole segment relationship.
[0040] Parameter correspondence should be established primarily based on parameter names. If parameter names are not completely consistent, correspondence should be established based on the relationship of the borehole section, the unit of measurement, and the purpose of the parameter. If all three are consistent, they are considered as the corresponding design parameters and actual on-site construction parameters. If any one of them is inconsistent, parameter correspondence should not be established, and the missing measured content or the added construction content should be recorded as construction deviation data.
[0041] Parameter correspondences are categorized into numerical parameters and substitution parameters based on their expression method. Numerical parameters are those that can be expressed using location, length, interval, or angle, including actual on-site construction parameters whose magnitude or direction can be compared under the slope design profile reference. Substitution parameters are those that cannot be expressed through numerical differences but can reflect changes in on-site execution relative to the design content. Charge structure and filling status are treated as substitution parameters.
[0042] The filling length is treated as a length-type parameter, while the filling material, filling compaction record, and filling method are treated as filling status, which is a replacement-type parameter.
[0043] When a design parameter exists in the blasting design data but the corresponding actual construction parameter does not exist in the construction measurement data, it is marked as missing measured content in the construction deviation data, and the deviation is not calculated. When an actual construction parameter exists in the construction measurement data but the corresponding design parameter does not exist in the blasting design data, it is marked as newly added construction content in the construction deviation data, and the deviation is not calculated. When both the design parameter and the actual construction parameter exist and are numerical parameters, proceed to S202 for position alignment and deviation calculation; when both the design parameter and the actual construction parameter exist and are replacement parameters, proceed to S203 to establish a replacement relationship.
[0044] S202. Calculate the deviation and direction of change of numerical parameters based on the slope design profile: After establishing the parameter correspondence, positional alignment is performed for numerical parameters. Positional parameters are compared using the slope design profile as a reference. Design parameters and actual on-site construction parameters are read along a comparison direction perpendicular to the slope design profile. A comparison direction pointing towards the excavation side is recorded as positive, and a comparison direction pointing towards the retained slope side is recorded as negative. Length, interval, and angle parameters are compared using the same unit of measurement. Actual on-site construction parameters and design parameters must first be converted to the same unit. If the units are not consistent, deviations are not calculated, and the discrepancy is marked in the construction deviation data as a unit inconsistency.
[0045] When aligning positional parameters, the direction perpendicular to the slope design outline is taken as the comparison direction at the location where the design parameters or actual on-site construction parameters are projected onto the slope design outline; when the comparison direction points to the excavation side, it is recorded as positive, and when the comparison direction points to the retained slope side, it is recorded as negative.
[0046] The deviation of numerical parameters is obtained by subtracting the design parameters from the actual on-site construction parameters. For location parameters, a positive deviation indicates a shift towards the excavation side, a negative deviation indicates a shift towards the retained slope side, and a zero deviation indicates no change in direction. For length, interval, and angle parameters, a positive deviation indicates an increase, a negative deviation indicates a decrease, and a zero deviation indicates no change in direction.
[0047] The deviation of numerical parameters is expressed by the following formula: ; in, Indicates the first In the relationship between the positions of the borehole segments, the first... Deviation of each numerical parameter; This represents the actual construction parameters on site from the measured construction data; This refers to the design parameters in the blasting design data; the dimensions of the three are the same as those of the first. All numeric parameters are consistent.
[0048] For example, in a certain borehole section relationship, the designed borehole spacing is 1.2 meters, and the actual measured borehole spacing is 1.5 meters. Both are interval parameters and have the same unit of measurement. Subtracting the designed borehole spacing from the actual measured spacing yields a deviation of 0.3 meters, which is recorded as an increase. In another borehole section relationship, the designed borehole inclination angle is 53 degrees, and the actual measured borehole inclination angle is 55 degrees. Both are angle parameters and have the same unit of measurement. Subtracting the designed borehole inclination angle from the actual measured borehole inclination angle yields a deviation of 2 degrees, which is recorded as an increase. If the actual construction position of a certain location parameter deviates from the design position towards the side of the retained slope, the deviation is recorded in the opposite direction, and the change is recorded as a deviation towards the side of the retained slope.
[0049] After processing in this step, numerical parameters are converted from the original records into deviations and directions of change under the same borehole segment relationship. Unchanged deviations are still written into the construction deviation data to preserve complete on-site execution records, but unchanged deviations are not included in the judgment of opposite directions of change in step S3.
[0050] S203. Record the substitution relationships of substitution parameters and generate construction deviation data: Subtraction is not used for replacement parameters. For the charge structure and filling state within the same borehole segment relationship, the design parameter field in the blasting design data and the actual construction parameter field in the field measurement data are read. When the contents of the two fields are the same, the replacement relationship is recorded as no replacement; when the contents of the two fields are different, the replacement relationship is recorded in the manner that the design parameter field points to the actual construction parameter field.
[0051] Taking the charge structure as an example, the blasting design data for a certain borehole segment relationship is recorded as intermittently uncoupled, while the actual construction measurement data is recorded as continuously uncoupled. Since the charge structure cannot be expressed by length or position differences, the deviation is not calculated during processing. Instead, the charge structure, intermittent uncoupled, continuously uncoupled, and corresponding borehole segment relationships are written into the same substitution relationship. Taking the tamping state as an example, if the tamping state field in the blasting design data and the actual construction measurement data are different, a substitution relationship is also formed in the same way; if the contents of the two fields are the same, it is recorded as no substitution.
[0052] When generating construction deviation data, the processing results of numerical parameters and replacement parameters are written in the order of borehole segment relationships. Numerical parameters include parameter name, design parameter, actual on-site construction parameter, deviation content, and direction of change. Replacement parameters include parameter name, design parameter, actual on-site construction parameter, and replacement relationship. Missing measured content, newly added construction content, and inconsistent units are also recorded as construction deviation data and written to the corresponding borehole segment relationship. The direction of change in the construction deviation data originates only from numerical parameters; replacement relationships, as records of changes in on-site execution content, are not included in the comparison of the direction of change of adjacent deviation content in step S3.
[0053] After step S2 is completed, the blasting design data and construction measurement data in the sample record are organized into construction deviation data. The construction deviation data are arranged in the order of the borehole segment relationship, and the deviation content and change direction of numerical parameters and the replacement relationship of replacement parameters are stored respectively, so that step S3 can read the construction deviation data along the borehole segment relationship and compare the change direction of adjacent deviation content.
[0054] Detailed implementation of step S3: Step S2 has generated construction deviation data, which stores the borehole segment relationship, the deviation content and direction of change of numerical parameters, and the replacement relationship of replacement parameters. When reading the construction deviation data in step S3, it does not directly use all deviation content as the basis for splitting. Instead, it first looks for directional conflicts of the same numerical parameter in the relationship between adjacent borehole segments, and then uses the post-blasting formation evaluation data at the same location for confirmation, so that the splitting boundary comes from the common direction of the construction deviation data and the post-blasting formation evaluation data.
[0055] S301. Reading of adjacent change directions and recording of direction conflicts: Read the construction deviation data obtained in step S2, keep the order of the borehole segment relationships in the construction deviation data unchanged, and process them item by item according to the names of the numerical parameters. Numerical parameters are those that can be expressed by position, length, interval or angle in step S2. Replacement parameters only retain the replacement relationship and do not participate in the comparison of adjacent change directions in this sub-step.
[0056] For the same numerical parameter, the direction of change in the relationship between two adjacent borehole segments is read sequentially according to the borehole segment relationship. The relationship between two adjacent borehole segments is defined as the preceding borehole segment relationship and the following borehole segment relationship. If the direction of change in the preceding borehole segment relationship is biased towards the excavation side, and the direction of change in the following borehole segment relationship is biased towards the preserved slope side, it is recorded as the opposite direction of change; if the direction of change in the preceding borehole segment relationship is increasing, and the direction of change in the following borehole segment relationship is decreasing, it is recorded as the opposite direction of change; if the direction of change in the preceding borehole segment relationship is decreasing, and the direction of change in the following borehole segment relationship is increasing, it is recorded as the opposite direction of change.
[0057] If the direction of change in the previous or subsequent borehole segment relationship remains unchanged, it is not recorded as the opposite direction of change. When two adjacent borehole segment relationships belong to different numerical parameter classes, the direction of change is not compared. This sub-step generates candidate splitting information, which includes the name of the numerical parameter class, the previous borehole segment relationship, the subsequent borehole segment relationship, the previous direction of change, and the subsequent direction of change.
[0058] S302. Evaluation of State Transition Confirmation and Determination of Split Boundaries: The candidate splitting information only indicates that the construction deviation data has a directional conflict at the relationship between adjacent blast hole segments. It is also necessary to read the post-blast forming evaluation data in the same adjacent blast hole segment relationship to confirm whether the post-blast forming evaluation data has undergone an evaluation status transition at the same location. The evaluation status is the classification result of the post-blast forming evaluation data under the blast hole segment relationship. The evaluation status includes qualified records, unqualified records, and empty fields.
[0059] When the post-blast forming evaluation data already includes the acceptance conclusion, the acceptance conclusion is directly written into the evaluation status. When the post-blast forming evaluation data only includes the test value, the evaluation standard corresponding to the post-blast forming evaluation data is read, the test value is compared with the evaluation standard, and the record that meets the evaluation standard is written into the qualified record, and the record that does not meet the evaluation standard is written into the unqualified record. When there are multiple post-blast forming evaluation data within the same borehole segment relationship, if there is at least one unqualified record, the evaluation status of the borehole segment relationship is recorded as an unqualified record.
[0060] The evaluation criteria are derived from the forming quality requirements in the blasting design data, the acceptance records of completed construction sections, or the construction acceptance documents. The evaluation criteria include evaluation items, test value types, and allowable ranges. If the post-blast forming evaluation data lacks both acceptance conclusions and the corresponding evaluation criteria cannot be retrieved, the evaluation status of the borehole segment relationship is recorded as an empty field and is not included in the evaluation status transition judgment.
[0061] For the previous borehole segment relationship in the candidate splitting information, read the post-blast formation evaluation data from the corresponding sample record. If the post-blast formation evaluation data field is empty, the evaluation status of the previous borehole segment relationship is recorded as an empty field; if there is a non-compliant record in the post-blast formation evaluation data field, the evaluation status of the previous borehole segment relationship is recorded as a non-compliant record; if there are no non-compliant records and there are compliant records in the post-blast formation evaluation data field, the evaluation status of the previous borehole segment relationship is recorded as a compliant record. The evaluation status of the subsequent borehole segment relationship is obtained according to the same rules.
[0062] If both the evaluation status of the current borehole segment relationship and the evaluation status of the subsequent borehole segment relationship are not empty fields, and both are respectively a qualified record and an unqualified record, then the post-blast forming evaluation data is considered to have undergone an evaluation status transition at the same adjacent borehole segment relationship. If the evaluation status of either the current borehole segment relationship or the subsequent borehole segment relationship is an empty field, or both evaluation statuses are qualified records, or both evaluation statuses are unqualified records, then an evaluation status transition is not considered.
[0063] Candidate splitting information that simultaneously satisfies both opposite directions of change and evaluation state transition is used. The position between the previous and subsequent borehole segment relationships is determined as the splitting boundary, and the numerical parameter name, the previous direction of change, the subsequent direction of change, and the evaluation state transition are collectively recorded as the dominant deviation type. If multiple numerical parameters in the same adjacent borehole segment relationship satisfy the aforementioned conditions, the dominant deviation type is recorded separately according to the numerical parameter name, and multiple numerical parameters are not merged into a single dominant deviation type.
[0064] In one embodiment, construction deviation data are arranged sequentially according to the borehole segment relationships. For borehole spacing, the direction of change for the preceding borehole segment relationship is increasing, while the direction of change for the following borehole segment relationship is decreasing; both belong to the same numerical parameter class and have opposite directions of change. Continuing to read the post-blast forming evaluation data from the two borehole segment relationships, the evaluation status of the preceding borehole segment relationship is a qualified record, while the evaluation status of the following borehole segment relationship is an unqualified record, indicating a change in evaluation status. The processing result determines the position between the preceding and following borehole segment relationships as the split boundary, and identifies the record where the borehole spacing changes from increasing to decreasing and the evaluation status changes from qualified to unqualified as the dominant deviation type corresponding to the borehole spacing. If the evaluation status of both borehole segment relationships is qualified, the split boundary is not determined.
[0065] S303, Mutually Exclusive Subset Splitting and Bias Influence Rule Formation: After determining the split boundaries, the sample records are split according to the same dominant deviation type. For a single dominant deviation type, only the sample records under the corresponding numerical parameters are assigned. Sample records located before the split boundary and belonging to the same construction section are assigned to the first mutually exclusive subset, and sample records located after the split boundary and belonging to the same construction section are assigned to the second mutually exclusive subset. If there are multiple split boundaries for the same dominant deviation type, the split boundaries are first arranged according to the borehole segment relationship, and then the sample records between adjacent split boundaries are assigned to independent mutually exclusive subsets. Any sample record is assigned to only one mutually exclusive subset under the same dominant deviation type.
[0066] For numerical parameters that do not form a split boundary, if the construction deviation data does not show a reverse direction of change, or if the post-blast forming evaluation data does not show an evaluation state transition at the same adjacent borehole segment relationship, the corresponding sample record is marked as a continuous deviation type. The continuous deviation type is used to indicate that the same numerical parameter does not form a directional conflict position confirmed by the post-blast forming evaluation data along the borehole segment relationship.
[0067] After completing the mutual exclusion subset splitting, the splitting boundary, dominant deviation type, mutual exclusion subset, and continuous deviation type are written into the deviation influence rule. Each record in the deviation influence rule retains the numerical parameter name, borehole segment relationship, change direction, evaluation state transition, splitting boundary, and mutual exclusion subset affiliation, so that the discrimination results corresponding to different numerical parameters in the same construction segment are saved separately.
[0068] After step S3 is completed, the construction deviation data is organized into deviation influence rules. The deviation influence rules clearly record which adjacent borehole segment relationships form split boundaries, which sample records belong to mutually exclusive subsets corresponding to the dominant deviation type, and which sample records belong to the continuous deviation type. Step S4 can filter similar samples that are in the same deviation type as the initial field data according to the deviation influence rules.
[0069] Detailed implementation of step S4: Step S3 has already formed the deviation influence rules, which store the split boundary, dominant deviation type, mutually exclusive subsets, and continuous deviation type. Step S4 deals with the recommended construction section that has not yet been blasted. The available data is limited to the initial field data. Therefore, it is necessary to first convert the initial field data into the same expression as the construction deviation data, and then select similar samples within the range defined by the deviation influence rules to avoid mixing sample records under different deviation types for the same parameter recommendation result.
[0070] S401. Initial deviations for the proposed construction section: Read the initial on-site data of the section to be recommended for construction. The initial on-site data includes the design parameters of the section to be recommended for construction and the on-site conditions that can be obtained before blasting. The design parameters of the section to be recommended for construction represent the parameters to be used before blasting, and the on-site conditions that can be obtained before blasting represent the on-site conditions that have been confirmed before construction. Both are entered into the same comparison criteria as in step S2.
[0071] Read the borehole position relationships in the recommended construction section along the slope design outline, and organize the initial field data according to the borehole position relationship order. For numerical parameters in the initial field data, compare the field condition records obtainable before blasting of the recommended construction section with the design parameters of the recommended construction section within the same borehole position relationship. For positional parameters, determine the direction of change according to the deviation relative to the slope design outline. When the field condition record deviates from the excavation side relative to the design parameter, the direction of change is recorded as deviating from the excavation side; when the field condition record deviates from the design parameter from the retaining slope side, the direction of change is recorded as deviating from the retaining slope side. Length, interval, and angle parameters are compared using the same unit of measurement. When the field condition record is greater than the design parameter, the direction of change is recorded as increasing; when the field condition record is less than the design parameter, the direction of change is recorded as decreasing; when the field condition record is equal to the design parameter, the direction of change is recorded as no change.
[0072] For replacement parameters in the initial on-site data, the design parameter field and the on-site condition record field of the construction section to be recommended are read. If the contents of the two fields differ, a replacement relationship is established; if the contents are the same, no replacement is recorded. After this sub-step, the initial deviation content for the construction section to be recommended is generated. This initial deviation content includes borehole segment relationships, numerical parameter names, direction of change, and replacement relationships. The field names of the initial deviation content are consistent with the construction deviation data generated in step S2, enabling the deviation influence rules to be directly read and matched.
[0073] S402. Identify similar samples within the same deviation type: Read the deviation influence rules formed in step S3 and match the initial deviation content with the deviation influence rules. For numerical parameters in the initial deviation content, first search for the corresponding dominant deviation type and continuous deviation type in the deviation influence rules according to the numerical parameter name; if a dominant deviation type exists, determine the position of the borehole segment relationship of the construction section to be recommended relative to the split boundary, and determine the mutually exclusive subset located on the same split boundary side and with the same direction of change as the sample record range. If no dominant deviation type exists, or if the initial deviation content does not form a directional conflict with the dominant deviation type, determine the sample record corresponding to the continuous deviation type as the sample record range.
[0074] Similar samples are determined according to the sequential position of borehole segment relationships. When the number of borehole segment relationships in the recommended construction section and the completed construction section to which the sample record belongs is the same, the sequential distance is the number of intervals between their arrangement within their respective construction sections. The sample record with the fewest intervals is determined as a similar sample. When the number of borehole segment relationships in the recommended construction section and the completed construction section to which the sample record belongs is different, the sequential proportion of the recommended borehole segment relationships in the recommended construction section is calculated first, then the sequential proportion of the corresponding borehole segment relationships in the sample record is calculated, and the sample record with the smallest difference in sequential proportions is selected as a similar sample. The difference in sequential proportions is expressed by the following formula: ; in, Indicates the first section of the construction to be recommended. The relationship between the location of each borehole segment and the first segment in the completed construction section The sequential proportional difference between the positions of individual borehole segments; This indicates the order in which the recommended borehole sections are arranged within the recommended construction section; This indicates the total number of borehole segment relationships within the section to be recommended for construction; This indicates the order in which the corresponding borehole segment relationships of the sample records are arranged in the completed construction section; This indicates the total number of borehole segment relationships within the completed construction section to which the sample record belongs. When the construction section to be recommended or the completed construction section contains only one borehole segment relationship, the corresponding sequence ratio is recorded as zero. If the sequence distance or sequence ratio difference is the same, the sample record whose change direction is consistent with the initial deviation content is selected; if multiple sample records still exist, the sample record ranked first is selected according to the writing order in the blasting sample library.
[0075] When there are no qualified post-blast forming evaluation data records within the sample record range, the corresponding numerical parameters do not read the deviation content of similar samples. The parameter recommendation result retains the design parameters in the initial field data and records the unmatched state. For replacement parameters, the replacement parameters do not generate a dominant deviation type separately. When the sample record range for numerical parameters has been determined under the same borehole segment relationship, the replacement parameters read the qualified post-blast forming evaluation data records from the already determined sample record range and determine similar samples according to the sequential distance rule. When no sample record range for numerical parameters has been formed under the same borehole segment relationship, the replacement parameters determine similar samples from the qualified post-blast forming evaluation data records within the same construction section in the blasting sample library according to the sequential distance rule. When there are no qualified records, the parameter recommendation result retains the design parameter field content in the initial field data.
[0076] S403. Parameter recommendation results are generated from similar samples: After identifying similar samples, the blasting design data, actual construction data, and post-blast shaping evaluation data from these samples are read. For numerical parameters, the deviations between the actual construction data and the blasting design data in the similar samples are first read. Then, the deviations are applied to the design parameters of the section to be recommended, according to their positive or negative signs. When the deviation is positive, the recommended value is the result of adding the deviation to the design parameters of the section to be recommended; when the deviation is negative, the recommended value is the result of subtracting the absolute value of the deviation from the design parameters of the section to be recommended; when the deviation is zero, the recommended value is consistent with the design parameters of the section to be recommended. For location parameters, the deviations are applied to the design location of the section to be recommended, according to the recording direction biased towards the excavation side or the slope retention side.
[0077] Recommended values for numerical parameters are expressed using the following formula: ; in, Indicates the first section of the construction to be recommended. Recommended values for each numerical parameter; Indicates the first section of the construction to be recommended. Design parameters for a numerical class of parameters; Indicates the first among similar samples The deviation of each numerical parameter is obtained by subtracting the blasting design data of similar samples from the actual construction measurement data of similar samples.
[0078] For replacement parameters, the measured construction data field corresponding to the qualified record of the post-blast forming evaluation data in similar samples is read. When the measured construction data field differs from the blasting design data field, the measured construction data field is written into the parameter recommendation result as the recommended content; when the measured construction data field is the same as the blasting design data field, the design parameter field content of the construction section to be recommended is written into the parameter recommendation result. The parameter recommendation result saves the borehole segment relationship, numerical parameter name, recommended value, replacement parameter name, recommended content, similar sample source, and unmatched status.
[0079] In one embodiment, the hole spacing design parameter for the recommended construction section is 1.2 meters. The initial deviation matches the dominant deviation type corresponding to the hole spacing. Within the sample record range, there are similar samples with qualified post-blast forming evaluation data. The hole spacing blasting design data in the similar samples is 1.2 meters, while the actual measured hole spacing during construction is 1.5 meters. The actual measured data increases by 0.3 meters relative to the blasting design data, and the parameter change direction is increasing. During processing, the hole spacing design parameter for the recommended construction section is increased by 0.3 meters, resulting in a recommended hole spacing value of 1.5 meters. The charge structure blasting design data in the similar samples is intermittently decoupled, while the actual measured charge structure during construction is continuously decoupled, and the post-blast forming evaluation data is qualified. During processing, continuous decoupling is used as the recommended charge structure content for the recommended construction section.
[0080] After step S4 is completed, the initial on-site data of the construction section to be recommended is organized into initial deviation content. The deviation influence rule limits the sample recording range, and similar samples provide deviation content, parameter change direction and replacement relationship. Finally, a parameter recommendation result containing recommended value and recommended content is formed. Step S5 can reflect and verify the parameter recommendation result after the blasting of the construction section to be recommended is completed.
[0081] Detailed implementation of step S5: Step S4 has output the parameter recommendation results for the construction section to be recommended. The parameter recommendation results include the recommended values of numerical parameters and the recommended content of replacement parameters. After the blasting of the construction section is completed, the actual construction measurement data and the post-blast shaping evaluation data have been formed. Step S5 needs to put the actual execution content back into the same slope design outline benchmark and verify the deviation relationship between the parameter recommendation results and the on-site execution results.
[0082] S501. Generate recommendation verification results: The system receives the measured construction data and post-blast shaping evaluation data after blasting of the recommended construction section, reads the parameter recommendation results generated in step S4, and maintains the order of arrangement in the parameter recommendation results according to the borehole segment relationship. "Reflection" means placing the measured construction data, post-blast shaping evaluation data, and parameter recommendation results into the same slope design profile benchmark and the same borehole segment relationship, so that the recommended content, on-site execution content, and post-blast inspection content can correspond in the same record.
[0083] For numerical parameters, the recommended values are read from the parameter recommendation results, and then the actual construction parameters are read from the field measured data within the same borehole segment relationship. The actual construction parameters are subtracted from the recommended values to obtain the deviation of the construction measured data from the parameter recommendation results. For positional parameters, the direction of change is determined according to the deviation relationship relative to the slope design profile. When the construction measured data deviates from the parameter recommendation results towards the excavation side, the direction of change is recorded as deviating towards the excavation side; when the construction measured data deviates from the parameter recommendation results towards the retained slope side, the direction of change is recorded as deviating towards the retained slope side. For length, interval, and angle parameters, they are compared using the same unit of measurement. When the construction measured data is greater than the parameter recommendation results, the direction of change is recorded as increasing; when the construction measured data is less than the parameter recommendation results, the direction of change is recorded as decreasing; when the construction measured data is equal to the parameter recommendation results, the direction of change is recorded as no change.
[0084] For replacement parameters, the recommended content is read from the parameter recommendation results, and then the actual on-site construction parameters are read from the measured construction data within the same borehole segment relationship. If the recommended content matches the actual on-site construction parameters, it is recorded as no replacement; if the recommended content does not match the actual on-site construction parameters, it is recorded as a replacement relationship. Replacement parameters do not generate a change direction and are not included in the split boundary translation judgment.
[0085] Post-blast formation evaluation data is bound to the corresponding borehole segment relationship according to the unique attribution method in step S1. A recommended verification result is generated within each borehole segment relationship. The recommended verification result includes the borehole segment relationship, numerical parameter name, deviation content, direction of change, replacement relationship, and post-blast formation evaluation data. If a borehole segment relationship lacks post-blast formation evaluation data, the post-blast formation evaluation data field in the recommended verification result is recorded as an empty field, and empty fields do not participate in the evaluation state transition judgment.
[0086] S502, Verify the candidate update boundary corresponding to the dominant deviation type: Read the deviation influence rules formed in step S3, and verify the recommended validation results item by item according to the dominant deviation types in the deviation influence rules. Each dominant deviation type corresponds to a numerical parameter name, the original split boundary, the direction of change on both sides of the original split boundary, and the evaluation state transition record. During validation, only the recommended validation results with the same numerical parameter names as the dominant deviation types are read; other numerical parameters and replacement parameters are not read.
[0087] Compare the direction of change in the positional relationships of adjacent boreholes sequentially. For the same numerical parameter, if the direction of change in the previous borehole positional relationship is biased towards the excavation side, and the direction of change in the subsequent borehole positional relationship is biased towards the slope preservation side, record it as the opposite direction of change; if the direction of change in the previous borehole positional relationship is biased towards the slope preservation side, and the direction of change in the subsequent borehole positional relationship is biased towards the excavation side, record it as the opposite direction of change; if the direction of change in the previous borehole positional relationship is increasing, and the direction of change in the subsequent borehole positional relationship is decreasing, record it as the opposite direction of change; if the direction of change in the previous borehole positional relationship is decreasing, and the direction of change in the subsequent borehole positional relationship is increasing, record it as the opposite direction of change. If the direction of change in the previous or subsequent borehole positional relationship remains unchanged, it is not recorded as the opposite direction of change.
[0088] Post-blast formation evaluation data is read from the segment relationships of two adjacent boreholes at positions with opposite directions of change. An evaluation state transition is considered to have occurred when the two adjacent borehole segment relationships correspond to a qualified record and an unqualified record, respectively. An evaluation state transition is not considered to have occurred if either post-blast formation evaluation data field is empty, or if both adjacent borehole segment relationships are qualified records, or if both adjacent borehole segment relationships are unqualified records. Adjacent borehole segment relationships that simultaneously satisfy both opposite directions of change and evaluation state transition are recorded as candidate update boundaries.
[0089] The post-blast forming evaluation data in the recommended verification results are classified as qualified, unqualified, or empty fields according to the evaluation status acquisition rules in step S302. If a post-blast forming evaluation data field is empty, or the corresponding evaluation standard cannot be read, the evaluation status of the corresponding borehole segment relationship is recorded as an empty field.
[0090] In one embodiment, in the dominant deviation type corresponding to the hole spacing, the original split boundary is located between the third and fourth hole segment relationships. After the recommended construction section is blasted, the recommended verification results show that the hole spacing of the fourth hole segment relationship is increasing, while the hole spacing of the fifth hole segment relationship is decreasing. Simultaneously, the post-blast forming evaluation data for the fourth hole segment relationship is a qualified record, while the post-blast forming evaluation data for the fifth hole segment relationship is an unqualified record. Since the fourth and fifth hole segment relationships simultaneously exhibit opposite directions of change and evaluation state transitions, the processing result records the position between the fourth and fifth hole segment relationships as a candidate update boundary. If the post-blast forming evaluation data in both the fourth and fifth hole segment relationships are qualified records, no candidate update boundary is formed.
[0091] S503, Update the rules affecting deviations or stop updating: After the candidate update boundary is formed, it is compared with the original split boundary in the deviation influence rule. If the candidate update boundary is inconsistent with the original split boundary, the split boundary is shifted to the candidate update boundary. Before redetermining the mutually exclusive subsets, the recommendation verification results of the construction section to be recommended are converted into new sample records. The new sample records follow the method of writing the borehole segment relationship in step S1 and save the blasting design data, construction measurement data, post-blast forming evaluation data, deviation content, change direction, and replacement relationship of the construction section to be recommended. The new sample records and the existing sample records in the blasting sample library participate in the mutually exclusive subset division according to the updated split boundary. Then, the mutually exclusive subsets corresponding to the dominant deviation type are redetermined. Sample records located before the shifted split boundary and belonging to the same dominant deviation type are assigned to one side of the mutually exclusive subset, and sample records located after the shifted split boundary and belonging to the same dominant deviation type are assigned to the other side of the mutually exclusive subset. The updated bias impact rules retain the names of numerical parameters in the dominant bias type, replace the original split boundary positions, and write the shifted split boundary, the newly determined mutually exclusive subsets, and the evaluation state transition records in the recommendation verification results.
[0092] When multiple candidate update boundaries exist simultaneously, the candidate update boundary with the fewest intervals from the original split boundary is selected according to the borehole segment relationship. If two candidate update boundaries have the same number of intervals from the original split boundary, the candidate update boundary that is located after the original split boundary in the borehole segment relationship is selected. The above selection rule ensures that a dominant deviation type corresponds to only one translated split boundary in one update.
[0093] The deviation influence rule is stopped when no candidate update boundary exists in the recommended verification results, or when the candidate update boundary is consistent with the original split boundary. The deviation influence rule is stopped when the deviation content in the recommended verification results no longer shows opposite directions of change on both sides of the original split boundary. The deviation influence rule is stopped when the post-explosion forming evaluation data in the recommended verification results does not undergo an evaluation state transition on both sides of the original split boundary. Replacement relationships formed by replacement parameters are only written into the recommended verification results and do not change the split boundary in the deviation influence rule.
[0094] After completing or stopping the update of the deviation impact rules, the newly added sample records will be officially written into the blasting sample library. When the newly added sample records have already participated in the mutual exclusion subset partitioning after translation, the write status of the newly added sample records in the blasting sample library will be maintained. The newly added sample records save the blasting design data, actual construction measurement data, post-blast forming evaluation data, deviation content, change direction, replacement relationship, and evaluation status transition records of the construction section to be recommended, so that the blasting sample library saves the field execution results corresponding to the parameter recommendation results of this time.
[0095] After step S5 is completed, the actual construction data and post-blasting forming evaluation data of the construction section to be recommended are compiled into the recommended verification results. The recommended verification results are used to verify the split boundary position corresponding to the dominant deviation type. The deviation influence rule completes the split boundary translation when there is a candidate update boundary, and stops updating when there is no candidate update boundary.
[0096] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

When the detection range covers a borehole segment relationship, the post-blast formation evaluation data will be included in the covered borehole segment relationship. When the detection range covers multiple borehole segment relationships, the post-blast formation evaluation data will be assigned to the borehole segment relationship with the largest projection overlap length. When the projection overlap lengths are the same, the affiliation is determined according to the location of the detection center. If the detection center location falls on the dividing position, it is assigned to the blast hole segment relationship that is ranked earlier.
4. The method for recommending parameters for smooth blasting of fractured rock mass according to claim 1, characterized in that, The evaluation state during the evaluation state transition is formed in the following way: When the post-explosion molding evaluation data includes the acceptance conclusion, the acceptance conclusion will be written into the evaluation status. When the post-blast forming evaluation data includes test values, the evaluation standards are read from the forming quality requirements in the blasting design data, the acceptance records of the completed construction sections, and the construction acceptance documents. Test values that meet the evaluation standards are written into the qualified record, and test values that do not meet the evaluation standards are written into the unqualified record. When the evaluation criteria cannot be read, the evaluation status will be recorded as an empty field; When there are multiple post-blast formation evaluation data for the same borehole segment relationship, if there is an unqualified record, the evaluation status will be recorded as an unqualified record; if there is no unqualified record and there is a qualified record, the evaluation status will be recorded as a qualified record.
5. The method for recommending parameters for smooth blasting of fractured rock mass according to claim 1, characterized in that, Alignment blasting design data and actual construction measurement data include: For the same borehole section relationship, first establish the parameter correspondence between the design parameters and the actual construction parameters on site according to the parameter names; When parameter names are inconsistent, a parameter correspondence relationship shall be established according to the relationship of the borehole section, the unit of measurement and the purpose of the parameter. If the three are consistent, they shall be identified as the corresponding design parameters and actual on-site construction parameters. If any one of them is inconsistent, no parameter correspondence relationship shall be established. When the blasting design data contains design parameters but the actual construction measurement data does not contain corresponding on-site construction parameters, mark the missing measurement content in the construction deviation data; When the actual construction parameters exist in the construction measurement data but the corresponding design parameters do not exist in the blasting design data, the newly added construction content is marked in the construction deviation data.
6. The method for recommending parameters for smooth blasting of fractured rock mass according to claim 1, characterized in that, Replacement parameters in the parameter recommendation results are formed in the following way: Replacement parameters do not generate a dominant deviation type separately; When the sample record range for numerical parameters has been determined under the same borehole segment relationship, the sample record of the post-blast formation evaluation data that is qualified is read from the sample record range, and the similar sample is determined according to the similar sample determination method. When no sample record range of numerical parameters is formed under the same borehole segment relationship, similar samples are determined from the sample records of qualified post-blast formation evaluation data of the same construction section in the blasting sample library; when no qualified records exist, the parameter recommendation results retain the design parameter field content in the initial field data.
7. The method for recommending parameters for smooth blasting of fractured rock mass according to claim 1, characterized in that: The sample records are written into the borehole segment relationship field, blasting design data field, construction measured data field, and post-blast forming evaluation data field; Construction deviation data is written into the numerical parameter name, design parameter, actual on-site construction parameter, deviation content, direction of change, and replacement relationship; The deviation impact rules are written into the numerical parameter name, borehole segment relationship, change direction, evaluation state transition, split boundary, mutual exclusion subset affiliation, and continuous deviation type.
8. The method for recommending parameters for smooth blasting of fractured rock mass according to claim 1, characterized in that: The parameter recommendation results are written into the borehole segment relationship, numerical parameter name, recommended value, replacement parameter name, recommended content, similar sample source and unmatched status; It is recommended that the verification results be written into the borehole segment relationship, numerical parameter name, deviation content, change direction, replacement relationship and post-blast formation evaluation data; When the post-blast formation evaluation data field in the recommended verification results is empty, the corresponding borehole segment relationship will not be included in the evaluation state transition judgment.
9. The method for recommending parameters for smooth blasting of fractured rock mass according to claim 8, characterized in that, The rules for updating split boundaries and bias effects include: Before redetermining mutually exclusive subsets, the recommendation verification results of the construction sections to be recommended are converted into new sample records; New sample records are written in the order of borehole segment relationship, and the blasting design data, construction measurement data, post-blast forming evaluation data, deviation content, change direction and replacement relationship of the construction segment to be recommended are saved; Newly added sample records, together with existing sample records in the blasting sample library, participate in the mutual exclusion subset partitioning after translation. Regardless of whether the deviation affects the rule to complete the update or stop updating, the newly added sample records are written into the blasting sample library.
