Description

Technical Field

[0001] The invention relates to the technical field of electrical data processing, and in particular to an explosive point design method based on half-hole qualified rate. Background Art

[0002] At present, in the field of engineering blasting, the reasonable design of explosive points plays a vital role in the quality of blasting. As one of the important indicators for measuring blasting quality, the half-hole qualified rate directly reflects the integrity and stability of the rock mass retained after blasting. With the continuous expansion of engineering construction, blasting operations are facing more and more complex geological conditions and higher construction requirements.

[0003] Under existing technical conditions, the design of explosive points often relies on the experience of engineering technicians and limited theoretical calculations. However, this method has great limitations. The physical and mechanical properties of rocks under different geological conditions vary significantly, and traditional empirical design is difficult to accurately adapt to various complex geological environments. At the same time, due to the lack of effective integration and analysis of a large amount of blasting operation data, it is difficult to summarize laws and patterns with universal applicability, resulting in the design of explosive points being inaccurate and not optimized.

[0004] Therefore, the present invention proposes an explosive point design method based on the half-hole qualified rate. Summary of the invention

The best blasting scheme is generated according to the geological conditions within the range to be blasted, which improves the pertinence and adaptability of the scheme and ensures that the blasting effect is optimal. The explosive point design scheme in the best blasting scheme is determined as the best explosive point design scheme, which provides accurate operational guidance for actual blasting operations.

[0058] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0059] Embodiment 1:

[0060] The present invention provides a method for designing explosive points based on the half-hole qualified rate. Figure 1 ,include:

[0061] S1: obtaining a large number of available blasting operation instances, wherein the available blasting operation instances include geological conditions within the corresponding target blasting range, blasting schemes, half-hole qualified rate after blasting operation, and post-blasting status information;

[0062] S2: Build a blasting scheme generation model based on all available blasting operation instances;

[0063] S3: Generate the best blasting plan based on the geological conditions within the blasting range and the blasting plan generation model;

[0064] S4: All explosive point location designs in the best blasting plan are regarded as the best explosive point location design plan.

[0065] In this embodiment, the available blasting operation examples include blasting operation cases that are complete and meet specific requirements (such as the half-hole qualified rate is not less than a threshold) including geological conditions within the target blasting range, blasting schemes, half-hole qualified rate after blasting, and post-blasting status information. For example, a blasting operation in a mine, whose relevant data and information are complete and meet the conditions, can be used as an available blasting operation example.

[0066] In this embodiment, the target blasting range is a pre-set area where blasting is expected to be performed. For example, in a building demolition project, the area where the building to be demolished by blasting is located is designated.

[0067] In this embodiment, the geological conditions within the target blasting range refer to the geological conditions within the specific area of ​​the target blasting range, such as the stratum structure, geological composition, geological structure, etc. For example, the rock hardness, soil layer thickness, and the presence or absence of faults, etc.

[0068] In this embodiment, the blasting plan refers to the specific planning and arrangement of the blasting operation, including the type of explosives, the amount of explosives, the location of explosives, the detonation method, etc. For example, emulsion explosives are used, the total amount of explosives is several kilograms, and segmented detonation is adopted.

[0069] In this embodiment, the half-hole qualified rate after blasting operation is the ratio of the number of holes that meet the half-hole requirements (such as the half-hole shape is complete and the size meets the standard, etc.) to the total number of holes after blasting. For example, after a blast, 80 out of 100 holes meet the half-hole standard, and the half-hole qualified rate is 80%.

[0070] In this embodiment, the post-blasting status information includes relevant conditions after the blasting operation is completed, such as the actual blasting range, the number of flying rocks, the flying rock distance, the vibration sensing area, etc. For example, the actual blasting range exceeds the target range, 5 flying rocks are generated, and the maximum flying rock distance is 100 meters.

[0071] In this embodiment, the blasting scheme generation model: by learning and analyzing a large number of available blasting operation examples, a model can generate the best blasting scheme according to the input geological condition characteristics. For example: a model based on a neural network algorithm that can output the best blasting scheme according to the input geological characteristics.

[0072] In this embodiment, the best blasting plan is the best blasting plan output by the blasting plan generation model. For example, the plan that performs best in terms of safety, blasting effect, etc.

[0073] In this embodiment, the explosive point design plan: determines the specific plan of the explosive placement location. For example: in the target blasting area, mark the coordinates of each explosive placement point.

[0074] The beneficial effects of the above technology are: by obtaining a large number of available blasting operation examples containing rich information, sufficient data support is provided for subsequent model building and plan generation. By building a blasting plan generation model based on many examples, the relationship and rules between different geological conditions and blasting plans can be fully learned and summarized. The best blasting plan is generated according to the geological conditions within the range to be blasted, which improves the pertinence and adaptability of the plan and ensures that the blasting effect is optimal. The explosive point design plan in the best blasting plan is determined as the best explosive point design plan, which provides precise operational guidance for actual blasting operations. This method can improve the scientificity and accuracy of the blasting plan, reduce blasting risks, and improve blasting efficiency and quality.

[0075] Embodiment 2:

[0076] Based on Example 1, the explosive point design method based on the half-hole qualified rate, S1: obtain a large number of available blasting operation examples, refer to Figure 2 ,include:

[0077] S101: Acquire a large number of blasting operation instances, wherein the blasting operation instances include geological conditions within a corresponding target blasting range, blasting plans, half-hole qualified rate after blasting operation, and post-blasting status information;

[0078] S102: All blasting operation instances whose half-hole qualified rates after all blasting operations are not less than a half-hole qualified rate threshold are regarded as all available blasting operation instances.

[0079] In this embodiment, the half-hole qualified rate threshold is a pre-set standard value used to screen available blasting operation instances. Only blasting operation instances whose half-hole qualified rate after blasting is not less than this threshold will be regarded as available blasting operation instances for subsequent analysis and model training and other operations. For example: Assuming that the half-hole qualified rate threshold is set to 70%, then the blasting operation instances whose half-hole qualified rate reaches or exceeds 70% will be included in the available range.

[0080] The beneficial effects of the above technologies include: by obtaining a large number of blasting operation examples, the data source is broadened, providing rich samples for subsequent screening. The threshold of the half-hole qualified rate is set to screen out the available blasting operation examples with half-hole qualified rates, ensuring the quality and reliability of the selected data. Only selecting examples that meet the half-hole qualified rate requirements will help improve the accuracy and effectiveness of subsequent model building and solution generation. It can focus on successful and high-quality blasting operation cases, providing more valuable references for generating the best blasting solutions. It improves the quality and effectiveness of the data, laying a solid foundation for the subsequent blasting solution design.

[0081] Embodiment 3:

[0082] On the basis of Example 1, the explosive point design method based on the half-hole qualified rate, S2: Build a blasting plan generation model based on all available blasting operation examples, refer to Figure 3 ,include:

[0083] S201: extracting features of geological conditions within a corresponding target blasting range contained in each available blasting operation instance to obtain geological condition features of each available blasting operation instance;

[0084] S202: Analyze the post-blasting state information contained in each available blasting operation instance, and combine the corresponding half-hole qualified rate after the blasting operation to obtain the actual blasting effect evaluation value of each available blasting operation instance;

[0085] S203: The geological condition characteristics of each available blasting operation instance are used as the model input of a single training sample. At the same time, the blasting plan of each available blasting operation instance is used as the model output of the corresponding training sample, and the actual blasting effect evaluation value of each available blasting operation instance is used as the confidence of the corresponding training sample. In combination with the neural network algorithm, a blasting plan generation model is built.

[0086] In this embodiment, the actual blasting effect evaluation value of the available blasting operation instance is: a value calculated by a specific formula to measure the blasting effect of each available blasting operation instance. This value takes into account factors such as blasting range, flying stone situation, vibration sensing area, and half-hole qualified rate. For example: According to the formula, the actual blasting effect evaluation value of a certain available blasting operation instance is calculated to be 0.85, and the higher the value, the better the blasting effect.

[0087] In this embodiment, the geological condition characteristics of each available blasting operation instance are used as the model input of a single training sample, and the blasting scheme of each available blasting operation instance is used as the model output of the corresponding training sample, and the actual blasting effect evaluation value of each available blasting operation instance is used as the confidence of the corresponding training sample, and the blasting scheme generation model is built in combination with the neural network algorithm: This describes the process of building a blasting scheme generation model. The geological condition characteristics of each available blasting operation instance are used as the input data for model learning, the corresponding blasting scheme is used as the result that the model should output, and the actual blasting effect evaluation value is used to indicate the reliability of the training sample. These data are used, and the neural network algorithm is combined for training and adjustment, so as to build a model that can generate blasting schemes according to geological conditions. For example: For example, there are multiple available blasting operation instances, and their geological condition characteristics are input into the model one by one, and the model is expected to output the corresponding blasting scheme. At the same time, the effect and reliability of model learning are judged according to the actual blasting effect evaluation value, and the model is continuously optimized, and finally an effective blasting scheme generation model is built.

[0088] The beneficial effects of the above technology include: by extracting features from geological conditions, the key information of geological conditions can be accurately converted into features that can be used for model training. By analyzing the status information after blasting in combination with the half-hole qualified rate, the actual blasting effect evaluation value is obtained, providing more comprehensive feedback for model training. Taking geological condition characteristics as input, blasting scheme as output, and introducing the actual blasting effect evaluation value as confidence, the model training is more scientific and accurate. Building a blasting scheme generation model based on a neural network algorithm can fully learn and fit the complex relationship between geological conditions and blasting schemes. The accuracy and reliability of the blasting scheme generation model are improved, providing strong technical support for generating better blasting schemes.

For example: if the target three-dimensional blasting area is a rectangular parallelepiped, it is divided into 5 parts at equal intervals horizontally, then 5 target sub-blasting areas are obtained.

[0098] In this embodiment, the vertical stratum structural characteristic parameters of the target sub-blasting area are parameters describing the composition, structure and physical characteristics of the geological layer in the target sub-blasting area in the vertical direction, for example, including parameters such as rock type, rock thickness and rock hardness of the stratum.

[0099] In this embodiment, the stratigraphic structural characteristic matrix of the target sub-blasting area is a matrix constructed based on the longitudinal stratigraphic structural characteristic parameters of the target sub-blasting area, which is used to characterize the stratigraphic structural characteristics of the area. For example, the elements in the matrix may correspond to different stratigraphic structural characteristic values, and the stratigraphic characteristics of the area can be more intuitively and systematically represented through the matrix.

For example: a vector composed of a group of values ​​is used to represent various parameters in the geological structure feature.

[0102] The beneficial effects of the above technology include: dividing the target blasting area into equally spaced areas horizontally, which enables a more detailed analysis of the geological conditions of different sub-areas. Extracting the geological conditions of each sub-blasting area ensures a comprehensive consideration of the geological information. Determining the vertical stratigraphic structure characteristic parameters and generating a stratigraphic structure characteristic matrix can accurately describe the stratigraphic structure in matrix form. Sorting the stratigraphic structure characteristic matrix to obtain a matrix sequence is convenient for subsequent processing and analysis. Extracting geological structural features and generating characteristic vectors further enriches the description of geological conditions. Combining the stratigraphic structure characteristic matrix sequence and the geological structure characteristic vector to generate geological condition features makes the expression of geological conditions more comprehensive and accurate.

[0118] In this embodiment, all joint-like structural characteristic parameters and all fissure-like structural characteristic parameters of the available blasting operation instances are: in the available blasting operation instances, specific parameters of various characteristics of joints (such as density, strike, spacing, etc. of joints) and fissures (such as length, width, depth, etc. of fissures). For example: joint structural characteristic parameters may include that the average spacing of joints is 20 cm and the strike is 30 degrees north-east; fissure structural characteristic parameters may include that the maximum length of the fissure is 5 meters and the average width is 3 cm.

[0119] In this embodiment, based on all the joint-like structural characteristic parameters and all the fissure-like structural characteristic parameters contained in the geological structural characteristics of each available blasting operation instance, a geological structural characteristic vector of each available blasting operation instance is generated: the various characteristic parameters of the joints and fissures mentioned above are converted into a vector form through a certain mathematical method or model to facilitate subsequent analysis and processing. For example: Assuming that there are 10 characteristic parameters of joints and fissures, and the values ​​are 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 respectively, then the generated geological structural characteristic vector may be

[0123] On the basis of Example 4, the explosive point design method based on the half-hole qualified rate generates the geological condition characteristics of each available blasting operation instance based on the stratigraphic structure characteristic matrix sequence and geological structure characteristic vector of each available blasting operation instance, including:

[0124] Based on the stratigraphic structure characteristic matrix sequence and geological structure characteristic vector of each available blasting operation instance, the blasting energy priority propagation path in the target blasting area of ​​each available blasting operation instance is fitted;

[0125] Extract the characteristics of the stratigraphic structure characteristic matrix sequence and geological structure characteristic vector of each available blasting operation instance to obtain the basic geological condition characteristics of each available blasting operation instance;

[0126] The basic geological condition characteristics and the preferred propagation path of blasting energy of each available blasting operation instance are regarded as the geological condition characteristics of each available blasting operation instance.

[0127] In this embodiment, the preferred propagation path of the blasting energy in the target blasting area is: in the target blasting area, the route that the blasting energy is more inclined to propagate is analyzed based on factors such as geological conditions and structural characteristics. For example: For example, in a target blasting area with a specific stratum structure and geological structure, the blasting energy may preferentially propagate along a weak interface of a rock layer or along a specific crack direction.

[0128] In this embodiment, the stratigraphic structure feature matrix sequence and geological structure feature vector of each available blasting operation instance are feature extracted to obtain the basic geological condition features of each available blasting operation instance: by extracting and summarizing the key information in the stratigraphic structure feature matrix sequence and geological structure feature vector, features that can reflect the essential characteristics of the geological conditions in each available blasting operation instance are obtained. For example: from complex matrix and vector data, key features such as the main stratigraphic type and significant geological structure features are extracted as basic geological condition features.

[0129] In this embodiment, the basic geological condition characteristics of the available blasting operation instance are the characteristics that are extracted and can concisely and effectively describe the core and key aspects of the geological conditions in the available blasting operation instance. For example, they may include the main rock types, the approximate stratification of the strata, and the significant geological structure trends.

[0130] The beneficial effects of the above technology include: by fitting the priority propagation path of blasting energy, we can better understand the propagation law of blasting energy in geological conditions. The stratigraphic structure feature matrix sequence and geological structure feature vector are feature extracted to obtain basic geological condition characteristics, which effectively simplifies and extracts key information of complex geological information. The basic geological condition characteristics and the priority propagation path of blasting energy are used as geological condition characteristics to comprehensively and accurately describe the geological conditions, providing richer and more accurate input for the generation of blasting schemes. It helps to improve the matching degree between blasting schemes and actual geological conditions, optimize blasting effects, and reduce blasting risks.

[0132] On the basis of Example 7, the explosive point design method based on the half-hole qualified rate is based on the stratigraphic structure characteristic matrix sequence and geological structure characteristic vector of each available blasting operation instance, and the blasting energy priority propagation path in the target blasting area of ​​each available blasting operation instance is fitted, including:

[0133] Based on the multi-dimensional feature fusion method, all the stratigraphic structure feature matrices in the stratigraphic structure feature matrix sequence of each available blasting operation instance are simultaneously merged to obtain a stratigraphic structure feature dimension simplified matrix sequence of each available blasting operation instance;

[0134] All row vectors with the same row number in all the simplified matrices of the stratigraphic structure characteristic dimension in the stratigraphic structure characteristic dimension simplified matrix sequence of each available blasting operation instance are summarized as all single stratigraphic structure characteristic vectors of all target sub-blasting areas of each available blasting operation instance;

[0135] Input all single stratum structure feature vectors and geological structure feature vectors of the same longitudinal component ranking value of each available blasting operation instance into the blasting energy priority propagation area screening model, and screen out the blasting energy priority propagation area corresponding to the longitudinal component ranking value in all target sub-blasting areas within the target blasting area of ​​each available blasting operation instance;

[0136] Based on the blasting energy priority propagation area of ​​all longitudinal component ranking values, the blasting energy priority propagation path is roughly fitted in the target blasting area corresponding to the available blasting operation instance.

[0137] In this embodiment, based on the multi-dimensional feature fusion method, the row data of all stratigraphic structure feature matrices in the stratigraphic structure feature matrix sequence of each available blasting operation instance are merged at the same time to obtain a stratigraphic structure feature dimension simplified matrix sequence of each available blasting operation instance: a method capable of integrating multiple dimensional features is used to merge the row data of each matrix in the stratigraphic structure feature matrix sequence, thereby obtaining a set of simplified matrix sequences. For example: assuming that each stratigraphic structure feature matrix originally has 5 rows of data, the data at the same row position may be fused to perform some calculation (such as summing, averaging, etc.) to obtain new row data, form a new matrix, and form a stratigraphic structure feature dimension simplified matrix sequence.

[0138] In this embodiment, the simplified matrix sequence of stratigraphic structural feature dimensions is a sorted set of a series of simplified stratigraphic structural feature matrices obtained after the above-mentioned row data merging operation. For example, after processing, the originally complex matrices become a simpler matrix sequence that still reflects certain stratigraphic structural features.

[0139] In this embodiment, all row vectors with the same row number in all simplified matrices of the stratigraphic structural feature dimension in the stratigraphic structural feature dimension simplified matrix sequence of each available blasting operation instance are aggregated as all single stratigraphic structural feature vectors of all target sub-blasting areas of each available blasting operation instance: the row vectors with the same row number in the simplified matrix sequence are collected together to form a vector that can characterize the specific stratigraphic structural features of the target sub-blasting area. For example: For example, the first row vectors of all simplified matrices are aggregated into one vector as a single vector that describes a certain aspect of stratigraphic structural features.

[0140] In this embodiment, all single stratigraphic structural feature vectors of the target sub-blasting area are: specifically for the target sub-blasting area, a single vector that can reflect its specific stratigraphic structural characteristics obtained through the above-mentioned aggregation operation. For example, this vector can reflect the comprehensive stratigraphic structural situation of the sub-blasting area in a certain dimension.

[0141] In this embodiment, the blasting energy priority propagation area screening model is a model used to identify areas where blasting energy is more likely to be preferentially propagated from the target blasting area. For example, it may be constructed based on a machine learning algorithm, inputting relevant geological and structural feature data and outputting prediction results of blasting energy priority propagation areas.

[0142] In this embodiment, the longitudinal component ranking value is a serial number or identifier assigned after the longitudinal stratum components of the target blasting area are ranked. For example, in the order from shallow to deep, the longitudinal component ranking value of the first stratum component is 1, the second is 2, and so on.

[0143] In this embodiment, the blasting energy priority propagation area of ​​the longitudinal component ranking value is the area where the blasting energy is more easily propagated, which is selected from all the target sub-blasting areas corresponding to the longitudinal component ranking value. For example, when the longitudinal component ranking value is 3, the corresponding area determined to be the blasting energy priority propagation area may be the second target sub-blasting area of ​​all the target sub-blasting areas with the longitudinal component ranking value of 3, which is the blasting energy priority propagation area with the longitudinal component ranking value of 3.

[0144] In this embodiment, based on the blasting energy priority propagation areas of all longitudinal component ranking values, a blasting energy priority propagation path is roughly fitted in the target blasting area corresponding to the available blasting operation instance: the blasting energy priority propagation areas corresponding to each longitudinal component ranking value are comprehensively considered, and the propagation route of the blasting energy in the entire target blasting area is roughly inferred. For example: the areas corresponding to different ranking values ​​are connected to form a rough path as a preliminary estimated blasting energy priority propagation path.

[0145] The beneficial effects of the above technology include: merging row data through multi-dimensional feature fusion to obtain a simplified matrix sequence of stratigraphic structural feature dimensions, reducing data dimensions and improving processing efficiency. Summarizing row vectors with the same row sequence number to obtain a single stratigraphic structural feature vector facilitates unified analysis of the characteristics of different sub-blasting areas. The blasting energy priority propagation area screening model is used to screen out propagation areas with different longitudinal components, thereby improving the accuracy of propagation area determination. Based on the screening results, the blasting energy priority propagation path is roughly fitted, providing an important reference for the design of explosive points. The scientificity and effectiveness of the blasting energy propagation path fitting are improved, which helps to optimize the blasting plan and improve the blasting effect.
