[0002] Pre-splitting blasting technology is one of the common blasting methods in mining blasting technology. The working mechanism of this technology is to use the explosion of the uncoupled charge double-energy-gathering slot charge roll, the blasting stress wave, the expansion of high-pressure gas, and the air blade of the energy-gathering jet to accurately follow the line connecting the two adjacent holes, and organically combine at the moment when the rock mass forms cracks, so that the pre-cracks are formed, and fully expand and extend to achieve blasting on the slope. The advantages of this technology are obvious. It can effectively reduce ground vibration, reduce blasting noise, and reduce the damage to rocks or soil, thereby greatly improving the safety and efficiency of the project.

[0003] In the prior art, when pre-splitting and concentrated energy blasting is carried out on mine slopes, the setting of pre-splitting blasting points often lacks precise calculation and evaluation, resulting in unstable blasting effects, and sometimes even having a negative impact on the stability of the slope. In addition, due to the lack of effective data support, the optimization and adjustment of pre-splitting blasting points often rely on empirical judgment, which not only increases the project cost, but also may delay the construction period. Based on this, this scheme proposes a method for setting pre-splitting and concentrated energy blasting points on mine slopes to solve the above problems. Summary of the invention

[0045] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0047] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0048] See also Figure 1 As shown, the present invention provides a method for arranging pre-splitting and concentrated energy blasting points on a mine slope, comprising:

[0049] S1. Obtaining geographic structural parameters of the mine slope, where the geographic structural parameters include slope length and slope height;

[0050] S2. Setting a plurality of pre-splitting blasting points with different blasting parameters on the mine slope, and carrying out blasting treatment on each pre-splitting blasting point;

[0051] S3, collecting the rock crushing data of the mine slope at each pre-splitting blasting point, and summarizing them with the blasting parameters at the pre-splitting blasting point to obtain an evaluation data group of the pre-splitting effect of the mine slope, wherein the rock crushing data includes a standard blasting length and a standard blasting depth;

[0052] S4, obtaining safe blasting parameters, and calculating blasting length and blasting depth matching the safe blasting parameters according to the evaluation data group;

[0053] S5. Record the blasting length and blasting depth that match the safety blasting parameters as the first condition parameter and the second condition parameter respectively, and then determine the energy-concentrating blasting point on the mine slope in combination with the slope length and slope height.

[0054] As shown in the above steps S1-S5, the pre-splitting blasting technology is one of the common blasting methods in mining blasting technology. After the explosion of the uncoupled charge double-energy-gathering groove charge roll, the blasting stress wave, the expansion of the high-pressure gas, and the air blade of the energy-gathering jet accurately form cracks in the rock mass along the line connecting the two adjacent holes. In this embodiment, it is first necessary to obtain the geographical structure parameters of the mine slope, specifically including the area and height of the slope, and then it is necessary to set a plurality of pre-splitting blasting points on the slope. The blasting parameters designed for different pre-splitting blasting points are incremental designs, that is, the first The blasting parameters of one group are smaller than those of the second group. The blasting parameters include blasthole depth, blasthole spacing, blasthole caliber and blasthole charge. Each group of blasting parameters is set to 3 to 5 pre-splitting blasting points on the mine slope. After the pre-splitting blasting points are set, blasting treatment needs to be implemented on each pre-splitting blasting point to achieve the purpose of the test. After the blasting treatment is implemented, the rock crushing data of the mine slope under each pre-splitting blasting point needs to be collected. The rock crushing data includes standard blasting length and standard blasting depth, which is used as a basis to evaluate the blasting effect. , the rock crushing data and the blasting parameters under the pre-splitting blasting point are summarized to obtain the evaluation data group of the pre-splitting effect of the mine slope. By analyzing the rock crushing data, the blasting effect can be evaluated, thereby providing a corresponding basis for the subsequent adjustment of the blasting parameters. After obtaining the evaluation data group, it is necessary to obtain the safe blasting parameters. The safe blasting parameters are set based on safety considerations to ensure the safety of personnel and equipment during the blasting process. The blasting length and blasting depth that match the safe blasting parameters are calculated based on the evaluation data group. The purpose is to ensure the blasting effect while minimizing the damage to the stability of the slope. Finally, the blasting length and blasting depth that match the safe blasting parameters are recorded as the first condition parameter and the second condition parameter respectively. Combined with the slope length and slope height obtained previously, the energy-gathering blasting point is determined on the mine slope. The determination of the energy-gathering blasting point comprehensively considers the first condition parameter and the second condition parameter to ensure the blasting effect and safety. In this way, the pre-splitting energy-gathering blasting point can be effectively arranged on the mine slope, thereby achieving the expected blasting effect.

[0055] In a preferred embodiment, when collecting the rock crushing data of the mine slope under each pre-splitting blasting point, the blasting lengths of the pre-splitting blasting points under the same blasting parameters are compared one by one, and the blasting depths of the pre-splitting blasting points under the same blasting parameters are compared one by one to obtain a first crushing deviation amount and a second crushing deviation amount;

[0056] Acquiring a length tolerance, and comparing the length tolerance with a first crushing deviation;

[0057] If the first crushing deviation is greater than or equal to the length allowable deviation, it indicates that the setting method of the pre-splitting blasting point does not meet the requirements, and the pre-splitting blasting point is readjusted for blasting treatment;

[0058] If the first crushing deviation is less than the length allowable deviation, it indicates that the setting method of the pre-splitting blasting point meets the requirements, and the blasting length of the pre-splitting blasting point under the same blasting parameters is retained;

[0059] Acquiring a depth tolerance, and comparing the depth tolerance with a second crushing deviation;

[0060] If the second crushing deviation is greater than or equal to the depth tolerance, it indicates that the setting method of the pre-splitting blasting point does not meet the requirements, and the pre-splitting blasting point is readjusted for blasting treatment;

[0061] If the second crushing deviation is less than the allowable depth deviation, it indicates that the setting method of the pre-splitting blasting point meets the requirements and the blasting depth of the pre-splitting blasting point under the same blasting parameters is retained.

[0062] In this embodiment, when performing rock crushing operations on the mine slope, it is necessary to perform detailed measurements and data collection on each pre-splitting blasting point. Specifically, the blasting lengths of the pre-splitting blasting points under the same blasting parameter conditions will be measured and recorded one by one, and the blasting depths will be measured and recorded one by one, and the blasting lengths under the same blasting parameter conditions will be subtracted in pairs. Similarly, the blasting depths under the same blasting parameter conditions will also be subjected to corresponding pairwise subtraction processing, so that the crushing deviation of each pre-splitting blasting point can be calculated, and then a preset allowable deviation is introduced. The allowable deviation is a threshold value set according to engineering requirements and safety standards. The crushing deviation actually measured is compared with the allowable deviation to determine whether the setting of the pre-splitting blasting point is reasonable. If, after comparison, it is found that the crushing deviation is greater than or equal to the allowable deviation, it means that the current The setting method of the pre-splitting blasting points cannot meet the engineering requirements and there is a large deviation. In this case, it is necessary to readjust the setting of the pre-splitting blasting points, including adjusting the blasting parameters, blasting position, etc., and then perform blasting again until the crushing deviation is less than the allowable deviation. On the contrary, if the crushing deviation is less than the allowable deviation, this indicates that the current setting method of the pre-splitting blasting points is reasonable and can meet the engineering requirements. In this case, these pre-splitting blasting points can be retained, and their blasting lengths and blasting depths under the same blasting parameters can be recorded as a reference for subsequent operations. In addition, when the setting method of the pre-splitting blasting points meets the requirements, the blasting lengths of the pre-splitting blasting points under the same blasting parameters are summed and averaged to obtain the standard blasting length, and then the blasting depths of the pre-splitting blasting points under the same blasting parameters are summed and averaged to obtain the standard blasting depth.

[0063] In a preferred embodiment, the step of calculating the blasting length and blasting depth matching the safe blasting parameters based on the evaluation data set comprises:

[0064] S401, obtaining a data set for evaluating the effect of pre-splitting blasting of a mine slope;

[0065] S402, sorting the evaluation data groups according to the values ​​of blasting depth and blasting length, wherein the evaluation data groups are arranged in ascending order;

[0066] S403, obtaining the increment of the blasting parameter in each evaluation data group, and recording it as a precondition parameter;

[0067] S404, obtaining the difference of blasting length and the difference of blasting depth in the evaluation data group, and recording the difference of blasting length as the first post-condition parameter, and recording the difference of blasting depth as the second post-condition parameter;

[0068] S405, calculating the correlation coefficient between the blasting length and the increment of the blasting parameter, and the correlation coefficient between the blasting depth and the increment of the blasting parameter according to the precondition parameter, the first postcondition parameter and the second postcondition parameter;

[0069] S406. Construct a correlation function based on the correlation coefficient, and calculate the blasting length under the safe blasting parameters based on the correlation function, and record it as the first condition parameter, and the blasting depth under the safe blasting parameters, and record it as the second condition parameter.

[0070] As described in the above steps S401-S406, in order to ensure that the effect of the pre-splitting blasting of the mine slope reaches the expected goal, first, it is necessary to collect an evaluation data group reflecting the effect of the pre-splitting blasting of the mine slope, and then extract the incremental amount of the blasting parameter from each evaluation data group and record it as a pre-condition parameter. After that, the difference in the blasting lengths in adjacent evaluation data groups is recorded as the first post-condition parameter, and the difference in the blasting depths in adjacent evaluation data groups is recorded as the second post-condition parameter. On this basis, the correlation between the blasting effect and the blasting parameters is analyzed. The correlation coefficient between the blasting length and the incremental amount of the blasting parameter = the first post-condition parameter / pre-condition parameter, and the correlation coefficient between the blasting depth and the incremental amount of the blasting parameter = the second post-condition parameter / pre-condition parameter. Since the correlation between the blasting length and the incremental amount of the blasting parameter The calculation results of the correlation coefficient between the blasting depth and the increment of the blasting parameter are not absolute integer values. In order to increase their accuracy, the quotient values ​​in the calculation results of the correlation coefficient between the blasting length and the increment of the blasting parameter, and the correlation coefficient between the blasting depth and the increment of the blasting parameter are recorded as the pre-main coefficient, and the remainder is used as the pre-subordinate coefficient to ensure that the subsequent construction of the correlation function is more accurate. Since there are multiple groups of evaluation data groups, there are also multiple groups of corresponding pre-condition parameters, first post-condition parameters and second post-condition parameters. When determining the main coefficient between the blasting length and the increment of the blasting parameter, and the main coefficient between the blasting depth and the increment of the blasting parameter, the standard function of the main coefficient between the blasting length and the increment of the blasting parameter is: In the formula, a1 represents the main coefficient between the blasting length and the increment of the blasting parameter, n1 represents the number of quotients between the blasting length and the increment of the blasting parameter, m1 represents the total increment of the blasting parameter, and C i and C i-1 represents the quotient between the adjacent blasting length and the increment of the blasting parameter, n2 represents the number of quotients between the blasting depth and the increment of the blasting parameter, and the standard function of the main coefficient between the blasting depth and the increment of the blasting parameter is: a2 represents the main coefficient between blasting depth and the increment of blasting parameters, m2 represents the total increment of blasting parameters, h i and h i-1It represents the quotient between adjacent blasting depths and the increments of blasting parameters. When determining the subordinate coefficient, the remainders calculated between each group of blasting lengths and the increments of blasting parameters are directly summed and averaged, and the output is the subordinate coefficient between the blasting length and the increments of blasting parameters. Similarly, the calculation process of the subordinate coefficient between the blasting depth and the increments of blasting parameters is consistent with the calculation process of the subordinate coefficient between the blasting length and the increments of blasting parameters, and will not be repeated here. Finally, the correlation function between the blasting length and the blasting parameters, as well as the correlation function between the blasting depth and the blasting parameters are constructed based on the obtained correlation coefficients. , the correlation function between blasting length and blasting parameters is: R1 = a1x1 + b1, where R1 is the increment (difference) of blasting parameters, a1 represents the main coefficient between blasting length and the increment of blasting parameters, b1 is the subordinate coefficient between blasting length and the increment of blasting parameters, x1 represents the difference between blasting lengths, and the correlation function between blasting depth and blasting parameters is: R2 = a2x2 + b2, where R2 is the increment (difference) of blasting parameters, a2 represents the main coefficient between blasting depth and the increment of blasting parameters, b2 is the subordinate coefficient between blasting depth and the increment of blasting parameters, and x2 represents the difference between blasting depths. , then the known safe blasting parameters and the blasting parameters in the evaluation data set are subjected to difference processing, and R1 used in the correlation function between the input blasting length and the blasting parameters, and R2 used in the correlation function between the input blasting depth and the blasting parameters can be obtained. The difference between the blasting length under the safe blasting parameters and the blasting length in the known evaluation data set can be calculated by the formula R1=a1x1+b1, and recorded as the length difference parameter (length difference parameter=blasting length under safe blasting parameters-blasting length in the known evaluation data set). Since the blasting length in the evaluation data set is a known quantity, the blasting length under the safe blasting parameters=the known evaluation length. The blasting length in the data group + the length difference parameter, and the blasting length under the safe blasting parameters will also be recorded as the first condition parameter. Similarly, the difference between the blasting depth under the safe blasting parameters and the blasting depth in the known evaluation data group can be calculated through the formula R2=a2x2+b2, and recorded as the depth difference parameter (depth difference parameter=blasting depth under safe blasting parameters-blasting depth in the known evaluation data group). Since the blasting depth in the evaluation data group is a known quantity, the blasting depth under the safe blasting parameters=blasting depth in the known evaluation data group + depth difference parameter. At the same time, the blasting depth under the safe blasting parameters will be recorded as the second condition parameter.

[0071] In a preferred embodiment, the step of determining the concentrated blasting point on the mine slope in combination with the slope length and slope height includes:

[0072] Obtain the slope length and slope height of the mine slope;

[0073] Obtaining a first condition parameter and a second condition parameter, and combining the first condition parameter with the slope length, and combining the second condition parameter with the slope height, to obtain the number of concentrated energy blasting points;

[0074] Starting from the edge of the mine slope, concentrated energy blasting points are arranged on the mine slope according to the number of concentrated energy blasting points.

[0075] As mentioned above, in order to accurately determine the position of the concentrated blasting points on the mine slope, it is first necessary to obtain the specific size parameters of the mine slope, including the length and height of the slope, and then it is necessary to obtain the first condition parameter and the second condition parameter, and determine the number of concentrated blasting points in combination with the length and height of the mine slope. The length of the mine slope corresponds to the first condition parameter, and the height of the mine slope corresponds to the second condition parameter. Finally, taking the edge of the mine slope as the starting point, according to the calculated number of concentrated blasting points, they can be arranged on the mine slope. The calculation formula for the number of concentrated blasting points is: the number of concentrated blasting points arranged in the length direction = slope length / first condition parameter. First, concentrated blasting is performed based on the number of concentrated blasting points arranged in the length direction. In order to ensure the uniformity and safety of the blasting effect, the spacing between the concentrated blasting points can be appropriately adjusted to adapt to different geological conditions and blasting requirements. For example, in the length direction of the slope, if the first condition parameter is small , it means that more concentrated blasting points are needed to ensure the blasting effect. At this time, the spacing between the concentrated blasting points can be appropriately reduced to ensure the uniformity of the blasting effect. On the contrary, if the first condition parameter is large, it means that fewer concentrated blasting points are needed. At this time, the spacing between the concentrated blasting points can be appropriately increased to avoid slope damage caused by excessive concentrated blasting. In the height direction of the slope, it is also necessary to arrange the concentrated blasting points according to the second condition parameter. The number of concentrated blasting points arranged in the depth direction = slope height / second condition parameter. Since the slope height in different areas of the slope may be inconsistent, the change of slope height needs to be considered when arranging the concentrated blasting points to ensure the uniformity and safety of the blasting effect. The specific needs are adjusted according to the actual situation of the slope. The arrangement method of the concentrated blasting points is one of linear arrangement and circular arrangement. In this way, the concentrated blasting technology can be effectively utilized to improve the efficiency and safety of mining.

By accurately measuring and analyzing these data, the system can provide a reliable basis for subsequent blasting design. The pre-test module is responsible for conducting a series of pre-splitting blasting tests on the mine slope. During the test, the system will set up multiple pre-splitting blasting points at different locations on the slope and apply different blasting parameters to these points, such as charge amount, hole spacing, etc. Through these tests, the blasting effects under different parameters can be observed and recorded to provide experimental data for subsequent optimization. The task of the data summary module is to collect the various The system collects the rock crushing data of the pre-splitting blasting point and summarizes and analyzes these data with the corresponding blasting parameters. Through comparative analysis, the system can evaluate the influence of different blasting parameters on the pre-splitting effect of the mine slope, thereby obtaining a set of evaluation data groups that can reflect the pre-splitting effect of the mine slope. The rock crushing data includes but is not limited to the standard blasting length and standard blasting depth. The main function of the measurement module is to calculate the blasting length and blasting depth that match the safe blasting parameters based on the evaluation data group. The safe blasting parameters refer to the maximum blasting parameters that meet the safety regulations. The blasting point layout module is responsible for recording the blasting length and blasting depth that match the safe blasting parameters calculated by the measurement module as the first condition parameter and the second condition parameter, respectively. Then, combined with the length and height of the slope, the system can accurately determine the location of the energy-gathering blasting point on the mine slope. In this way, the system can ensure the efficiency and safety of blasting operations while minimizing the negative impact on the environment.
