[0028] In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular architectures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application can be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known methods, devices, circuits, and

[0029] It is to be understood that the terminology "including", when used in the present specification and in the following claims, indicates the presence of the described features, integers, steps, operations, elements, and / or components but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0030] At present, both underground mining and open-pit mining cannot do without blasting work. The blasting work is to blast the ore rock into a certain size and a blasting pile according to the engineering requirements, so as to strip the ore rock from the whole, and create working conditions for subsequent mining and transportation.

[0031] However, the amount of explosive required for blasting the ore rock is usually set according to artificial experience at present, which leads to unreasonable setting of the amount of blasting explosive and often cannot achieve good blasting effect. When the amount of blasting explosive is too much, the ore rock may be overblasted, and thus the ore rock or the construction environment that does not need to be blasted is damaged, which affects the safety production.

[0032] For example, when the amount of blasting explosive is too much, a well blocking accident may occur, which brings great hidden dangers to transportation. Moreover, when a large-section roadway in a mine is blasted, the vibration wave generated by too much explosive amount may damage other stable roadway surrounding rocks, so that the roadway roof is disturbed and a roof falling accident occurs, causing personnel casualties.

[0033] Based on this, the embodiments of the present application provide a method for determining the amount of blasting explosive, which can be applied to terminal devices such as tablet computers, notebook computers, ultra-mobile personal computers (UMPC), etc. The embodiments of the present application do not make any limitation on the specific type of terminal device.

[0034] Please refer to Figure 1 , Figure 1 An implementation flowchart of a method for determining the amount of blasting explosive provided by the embodiments of the present application is shown, and the method comprises the following steps:

[0035] S101, determining a first vibration intensity required by explosive to be generated when blasting a to-be-blasted region according to a first geological parameter of the to-be-blasted region.

[0036] In applications, the first geological parameter can be determined according to a geological detector. The first geological parameter includes, but is not limited to, the composition of the ore rock, the rock dip angle, the principal stress when the ore rock is destroyed, and the compressive strength, without limitation.

[0037] In applications, the first vibration intensity includes, but is not limited to, the vibration speed, the vibration acceleration, the vibration frequency, and the vibration time of the vibration waveform caused by blasting, without limitation. In this embodiment, the vibration frequency can be used as the first vibration intensity to represent the attenuation law of the first vibration intensity caused by the vibration under the action of blasting at different first explosive amounts and different first distances.

[0038] In applications, the blasting explosive amount determination device can be preconfigured with an association relationship between the preset geological parameter and the preset vibration intensity. The preset vibration intensity can be considered as the vibration intensity required by the explosive when blasting the ore rock composed of the preset geological parameter. For example, the vibration intensity required to destroy the rock mass with different geological parameters can be determined according to the known failure criterion of jointed rock mass.

[0039] Based on this, the blasting explosive amount determination device can determine the first vibration intensity required by the explosive when blasting the to-be-blasted region according to the association relationship after determining the first geological parameter of the to-be-blasted region.

[0040] S102, determining a first region with an interval distance less than a preset distance from the to-be-blasted region; the second vibration intensity corresponding to the first region is less than the first vibration intensity.

[0041] In applications, the preset distance can be set according to actual conditions, without limitation. It should be noted that if the interval distance between the first region and the to-be-blasted region is less than the preset distance, it can be considered that the vibration wave generated by the explosive when blasting the to-be-blasted region can have a strong impact on the first region.

[0042] In applications, the way to determine the second vibration intensity corresponding to the first region is similar to the way to determine the first vibration intensity in S101, which will not be described in detail.

[0043] It can be understood that when blasting the to-be-blasted region, the explosive amount needs to generate a vibration wave greater than or equal to the second vibration intensity. However, since the second vibration intensity corresponding to the first region is less than the first vibration intensity, the vibration wave may also destroy the first region when it is transmitted to the first region.

[0044] In addition, when the corresponding vibration intensity of other regions is less than the first vibration intensity, and the interval distance from the region to be blasted is greater than the preset distance, it can be considered that the vibration intensity of the vibration wave generated by the explosive in the region to be blasted after transmitting the interval distance is far from enough to damage any region. Therefore, in the embodiment, the region with the interval distance greater than the preset distance does not need to be considered.

[0045] S103, predicting a first target explosive amount required for blasting the region to be blasted according to the first vibration intensity, the first geological parameter, and a pre-designed calculation model, wherein the pre-designed calculation model is used to represent the factor relationship between the vibration intensity, the geological parameter, and the explosive amount.

[0046] In application, the pre-designed calculation model is a model obtained by analyzing the actual situation in advance, and is used to represent the factor relationship between the vibration intensity, the geological parameter, and the explosive amount. When the pre-designed calculation model is generated, a social science statistical software (Statistical Package for the Social Sciences SPSS) can be used to perform a multi-factor nonlinear regression analysis, and details are not described herein.

[0047] Specifically, the blasting explosive amount determination apparatus can first determine a first monitoring parameter between the blasting vibration instrument and each blasting point; the first monitoring parameter includes a first distance between the blasting vibration instrument and the blasting point and a target geological parameter of the blasting point; then, target vibration parameters of each blasting point collected by the blasting vibration instrument are acquired; the target vibration parameters include a target vibration intensity generated by the explosive blasting; the first explosive amount of the explosive set at each blasting point is different. Finally, a pre-designed calculation model is generated according to the first monitoring parameter and the target vibration parameter.

[0048] In an embodiment, the blasting vibration instrument is used to collect various vibration waveforms generated during blasting to obtain the vibration parameters. The blasting vibration instrument can be a TC-4850 type blasting vibration recorder or a Beipiao blasting vibration recorder, and details are not limited herein. In the embodiment, the blasting vibration instrument can be a TC-4850 type blasting vibration recorder.

[0049] The target geological parameter can be determined in a manner similar to the determination of the first geological parameter in S101, and details are not described herein.

[0050] In an embodiment, the target vibration parameters of each blasting point can be collected by multiple blasting vibration instruments, and the first distance between each blasting vibration instrument and the blasting point is different. Specifically, in the embodiment, two blasting vibration instruments can be set at each blasting point.

[0051] And, in order to accurately obtain the attenuation law of the target vibration intensity under different target geological parameters, different first explosive amounts and different first distances, the positions of the blasting points can be set at the working face with large blasting operations in the mine as much as possible.

[0052] The target vibration parameters and the first monitoring parameters can be as shown in Table 1:

[0053] Table 1:

[0054]

[0055] In Table 1, there are four blasting points S1, S2, S3 and S4, each of which has two monitoring points with different first distances from the blasting points. Table 1 above shows the target vibration parameters detected at different blasting points under different first explosive amounts, different first distances and different geological parameters. The vibration velocity is the maximum value of the measured multiple velocities.

[0056] Specifically, referring to Figure 2 , Figure 2 A1 monitoring point vibration waveform diagram provided by an embodiment of the present application. After obtaining the vibration waveform diagram, the vibration frequency, vibration velocity, vibration time, vibration acceleration and vibration frequency, etc. can be obtained according to the preset waveform analysis tool.

[0057] The waveform analysis tool can be a blasting vibration analysis software, which can process the collected vibration waveform. For example, the first derivative function in the waveform analysis tool can be clicked to differentiate the vibration velocity and obtain the vibration acceleration waveform diagram of the vibration waveform.

[0058] In an embodiment, the pre-designed calculation model can be a model generated by multi-factor nonlinear regression analysis with the target vibration intensity as the dependent variable and the target geological parameter, the first explosive amount and the first distance from the explosive as the independent variable. Specifically, the pre-designed calculation model can be represented as follows:

[0059] A=KQ m R n ;

[0060] Wherein, A is a physical quantity of the target vibration intensity (for example, one of the vibration frequency, the vibration velocity and the vibration acceleration), K is the target geological parameter; Q is the first explosive amount; R is the first distance from the blasting point; m, n are index coefficients.

[0061] It should be noted that the above formula is only an example of the target vibration intensity, and the physical quantity of different target vibration intensity is usually different from the corresponding pre-design calculation model. In this embodiment, the target vibration intensity is taken as an example of vibration frequency, and the pre-design calculation model thereof can be:

[0062]

[0063] wherein f is the vibration frequency; k is a preset blasting method coefficient; K is the target geological parameter; Q is the first explosive amount; and R is the first distance.

[0064] When the target vibration intensity is the vibration frequency, the pre-design calculation model thereof can be:

[0065]

[0066] wherein N is the vibration frequency, and z is a constant greater than 1.

[0067] When the target vibration intensity is the vibration acceleration, the pre-design calculation model thereof can be:

[0068]

[0069] wherein a is the vibration acceleration.

[0070] Based on the pre-design calculation model corresponding to each of the above target vibration intensities, it can be determined that the vibration frequency generated during blasting is positively correlated with the first explosive amount and negatively correlated with the first distance. In addition, when the first distance increases, the vibration acceleration generated during blasting of different first explosive amounts all shows a decreasing trend, with a relatively fast decay in the early stage and a slow decay in the later stage. Moreover, with the increase of the explosive amount, the vibration acceleration under the same first distance increases. In addition, when the first distance increases, the vibration frequency generated during blasting of the same target explosive amount decreases, and the vibration frequency generated during blasting of different target explosive amounts shows a decreasing trend.

[0071] Based on the above explanation of the pre-design calculation model, after the first vibration intensity and the first geological parameter are determined, the first vibration intensity and the first geological parameter can be introduced into the pre-design calculation model to obtain the first target explosive amount required for blasting the to-be-blasted area.

[0072] It should be noted that the explosion point of the explosive is usually set in the to-be-blasted area, so when the blasting area is smaller than the preset area, the R value (first distance) in the formula corresponding to each of the above pre-design calculation models is 0. The preset area can be set according to the actual situation, and no limitation is made herein.

[0073] Therefore, the first target explosive amount can be determined according to the first vibration intensity and the first geological parameter.

[0074] However, the range of the blasting area is usually larger than the preset area, i.e., larger than the preset area. Therefore, if the first distance is determined as 0, the first target explosive amount obtained by the first distance may not be able to effectively blast the blasting area.

[0075] Therefore, in order to reasonably determine the first target explosive amount and optimize the blasting effect of the blasting area, the blasting explosive amount determination device can first determine a critical point in the blasting area that is farthest from the preset blasting point, and then obtain a target distance between the preset blasting point and the critical point. Then, the first vibration intensity, the first geological parameter and the target distance are introduced into the target calculation model to obtain the first target explosive amount.

[0076] In an embodiment, the preset blasting point can be set according to actual conditions, which is not limited. For example, in order to improve the blasting effect, the preset blasting point can be set as the center point of the blasting area.

[0077] Since the critical point is farthest from the preset blasting point, when the first target explosive amount is blasted at the preset blasting point, the target vibration intensity generated by the blasting can be sufficient to destroy the ore rock at the critical point, so as to avoid repeated blasting of the blasting area.

[0078] S104, determining an actual distance between the first area and the blasting area.

[0079] In application, the actual distance can be the distance between the preset blasting point in the blasting area and the boundary of the first area.

[0080] Specifically, the blasting explosive amount determination device can determine the distance between the preset blasting point in the blasting area and each boundary critical point in the first area, and then determine the minimum value of all distances as the actual distance.

[0081] In application, the preset blasting point can be the center point of the blasting area, or can be set according to actual conditions, which is not limited. The blasting explosive amount determination device can determine the distance between the preset blasting point and each boundary point according to the existing ranging sensor.

[0082] S105, predicting a third vibration intensity generated by the first target explosive amount on the first area according to the first target explosive amount, the actual distance and the preset calculation model.

[0083] In the application, based on the above S103, the explanation of the pre-designed calculation model can be known, and according to the pre-designed calculation model, the attenuation law of the first vibration intensity of the vibration caused by the blasting under the different first explosive quantity and the different first distance can be determined. Therefore, based on the first target explosive quantity, the actual distance and the pre-designed calculation model, the third vibration intensity generated by the first target explosive quantity of the explosive when the explosive is blasted at the preset blasting point can be back calculated.

[0084] S106, if the third vibration intensity is less than the second vibration intensity, it is determined that the explosive quantity required for blasting the region to be blasted is the first target explosive quantity.

[0085] In an embodiment, when the third vibration intensity is less than the second vibration intensity, it can be considered that after the blasting of the region to be blasted with the explosive of the first target explosive quantity, the vibration intensity of the vibration wave has been reduced to the third vibration intensity when the vibration wave is transmitted to the first region. However, the third vibration intensity is less than the second vibration intensity corresponding to the first region. Therefore, it can be considered that after the blasting of the region to be blasted with the explosive of the first target explosive quantity, the first region will not be damaged.

[0086] It can be understood that if the third vibration intensity is greater than or equal to the second vibration intensity, it can be considered that after the blasting of the region to be blasted with the explosive of the first target explosive quantity, the first region will be damaged. Therefore, the blasting explosive quantity determination device can predict the second target explosive quantity required for blasting the region to be blasted according to the second vibration intensity, the pre-designed calculation model and the first geological parameter. It should be added that when the explosive of the second target explosive quantity is blasted, the vibration intensity generated by the explosive on the first region should be less than the second vibration intensity.

[0087] Wherein, the way to predict the second target explosive quantity is similar to the way to predict the first target explosive quantity, which will not be described again.

[0088] It should be added that because the vibration intensity generated by the blasting of the explosive needs to be reduced, the above-mentioned second target explosive quantity is usually less than the above-mentioned first target explosive quantity. However, this will result in that the blasting effect of the region to be blasted may not achieve the expected effect. Therefore, the blasting explosive quantity determination device can also control the blasting of the region to be blasted with the explosive of the second target explosive quantity first, and determine the second region in the region to be blasted which is not blasted successfully. Finally, the second region is determined as a new region to be blasted, and the second target explosive quantity for blasting the new region to be blasted is predicted again.

[0089] It can be understood that after the blasting of the region to be blasted with the second target explosive quantity, the second region which has not been blasted is usually less. Therefore, it can be considered that at this time, the blasting of the second region with more blasting explosive quantity is not needed.

[0090] Based on this, the blasting explosive quantity determination apparatus can determine the second region as a new blasting region, and re-predict a second target explosive quantity for blasting the new blasting region. It should be noted that when re-determining the second target explosive quantity for the new blasting region, steps S101-S104 need to be performed again to avoid damaging the first region.

[0091] In this embodiment, when determining the first vibration intensity that the explosive needs to generate when blasting the blasting region according to the first geological parameter of the blasting region, a first region with a second vibration intensity smaller than the first vibration intensity is determined within a preset range that can be affected by blasting. Then, a first target explosive quantity for blasting the blasting region is predicted according to the first vibration intensity, the first geological parameter, and a pre-designed calculation model for representing the relationship between the vibration intensity and the geological parameter and the explosive quantity. Then, a separation distance between the first region and the blasting region is determined to predict a third vibration intensity generated on the first region when blasting with the first target explosive quantity according to the first target explosive quantity, the separation distance, and the pre-designed calculation model. Finally, when the third vibration intensity is smaller than the second vibration intensity, the explosive quantity required for blasting the blasting region can be determined as the first target explosive quantity. Based on this, not only can a reasonable first target explosive quantity be determined according to the actual first geological parameter of the blasting region and the pre-designed calculation model to optimize the blasting effect on the blasting region, but also the first region that does not need to be blasted and has a smaller vibration intensity can be avoided from being affected to maintain the construction environment.
