[0024] In the following description, specific details such as specific system structures, techniques, etc. are presented in order to thoroughly understand the embodiments of the present application. However, it should be clear for those skilled in the art that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits and methods are omitted in order not to obscure the description of the present application with unnecessary details.

[0025] It should be understood that when used in the specification and the appended claims of the present application, the term "comprising" indicates the presence of the described features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or sets thereof.

[0026] In addition, in the description of the specification and the appended claims of the present application, the terms "first", "second", "third" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0027] At present, both underground mining and open-pit mining cannot do without blasting work. Blasting work is to blast the ore rock into a certain size and blast 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.

[0028] However, the amount of explosive currently required for blasting of the ore rock is usually set according to artificial experience, resulting in unreasonable setting of the amount of explosive for blasting, which often cannot achieve good blasting effect. For example, when the amount of explosive for blasting is too small, repeated blasting is required, wasting manpower and resources; when the amount of explosive for blasting is too large, the ore rock may be excessively blasted, affecting safety production.

[0029] For example, when the amount of explosive for blasting is too large, well plugging accidents may occur, bringing great hidden dangers to transportation. Moreover, when large-section roadways in a mine are blasted, excessive explosive may generate vibration waves that damage the surrounding rock of the roadway, causing the roof of the roadway to be disturbed and leading to roof falling accidents, causing casualties.

[0030] Based on this, the embodiment of the present application provides a method for determining the amount of explosive for blasting, which can be applied to terminal devices such as tablet computers, notebook computers, ultra-mobile personal computers (UMPC), etc. The specific type of the terminal device is not limited in the embodiment of the present application.

[0031] Please refer to Figure 1 , Figure 1 The implementation flowchart of the method for determining the amount of explosive for blasting provided by the embodiment of the present application is shown, which includes the following steps:

[0032] S101, determining 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 first geological parameter of the blasting point.

[0033] In an embodiment, the blasting vibration instrument is used to collect various vibration waveforms generated during blasting to obtain vibration parameters. The blasting vibration instrument can be a TC-4850 type blasting vibration recorder or a Beipiao blasting vibration recorder, which is not limited. In the embodiment, the blasting vibration instrument can be a TC-4850 type blasting vibration recorder.

[0034] In an embodiment, the first monitoring parameter includes the first distance between the blasting vibration instrument and the blasting point and the first geological parameter of the blasting point. 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 damaged, and the compressive strength, which is not limited.

[0035] S102, obtaining a first vibration parameter of each blasting point collected by the blasting vibration instrument; the first vibration parameter includes a first vibration intensity generated by explosive blasting; the first amount of explosive set for each blasting point is different.

[0036] In an embodiment, the first vibration intensity includes, but is not limited to, vibration velocity, vibration acceleration, vibration frequency and vibration time of the vibration waveform caused by blasting, without limitation. In this embodiment, the vibration frequency can be taken as the first vibration intensity to represent the attenuation law of the first vibration intensity caused by blasting under different first explosive amounts and different first distances.

[0037] In an embodiment, each blasting point can collect the first vibration parameters by a plurality of blasting vibration instruments, and the first distance between each blasting vibration instrument and the blasting point is different. Specifically, in this embodiment, two blasting vibration instruments can be arranged at each blasting point.

[0038] In addition, in order to accurately obtain the attenuation law of the first vibration intensity under different first geological parameters, different first explosive amounts and different first distances, the position of the blasting point can be arranged at a working face with large blasting operation in the mine as much as possible.

[0039] In the table 1, the first vibration parameters and the first monitoring parameters can be as follows:

[0040] Table 1:

[0041]

[0042] In the 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 point. The table 1 shows the first vibration parameters detected under different first explosive amounts, different first distances and different corresponding geological parameters of the blasting points. The vibration velocity is the maximum value of the measured multiple velocities.

[0043] Specifically, referring to Figure 2 , Figure 2 A vibration waveform diagram of the A1 monitoring point in a blasting explosive amount determination method 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 and other first vibration parameters can be obtained according to the preset waveform analysis tool.

[0044] In the 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 point. The table 1 shows the first vibration parameters detected under different first explosive amounts, different first distances and different corresponding geological parameters of the blasting points. The vibration velocity is the maximum value of the measured multiple velocities.

[0045] S103, generating a target calculation model according to the first monitoring parameter and the first vibration parameter; the target calculation model is used to represent a factor relationship between the first vibration intensity and the first geological parameter and the first explosive quantity.

[0046] In an embodiment, the target calculation model is generated according to the first detection parameter and the first vibration parameter, and a multi-factor nonlinear regression analysis is performed with the first vibration intensity as a dependent variable and the first geological parameter, the first explosive quantity and the first distance as independent variables to generate the target calculation model.

[0047] In the generation of the target calculation model, a multi-factor nonlinear regression analysis can be performed by using a statistical package for social sciences (Statistical Package for the Social Sciences, SPSS), and no detailed description is given.

[0048] In an embodiment, the target calculation model can be expressed as follows:

[0049] A=KQ m R n ;

[0050] Wherein, A is a physical quantity of the first vibration intensity (for example, one of vibration frequency, vibration speed and vibration acceleration), K is the first geological parameter, Q is the first explosive quantity, R is the distance from the blasting point, and m and n are index coefficients.

[0051] It should be noted that the above formula is only an example of the first vibration intensity, and the corresponding target calculation model of different physical quantities of the first vibration intensity is usually different. In this embodiment, the first vibration intensity is taken as an example of vibration frequency, and the target calculation model thereof can be:

[0052]

[0053] Wherein, f is the vibration frequency, k is a preset blasting method coefficient, K is the first geological parameter, Q is the first explosive quantity, and R is the first distance.

[0054] When the first vibration intensity is the vibration frequency, the target calculation model thereof can be:

[0055]

[0056] Wherein, N is the vibration frequency, and z is a constant greater than 1.

[0057] And when the first vibration intensity is the vibration acceleration, the target calculation model thereof can be:

[0058]

[0059] wherein a is the vibration acceleration.

[0060] Based on the target calculation model corresponding to each of the various first 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 presents a decreasing trend, with relatively fast decay in the early stage and slow decay in the later stage tending to be flat. Moreover, with the increase of the first explosive amount, the vibration acceleration under the same first distance all increases. In addition, when the first distance increases, the vibration frequency generated during blasting of the same first explosive amount decreases, and the vibration frequency generated during blasting of different first explosive amounts presents a decreasing trend.

[0061] In S104, the target explosive amount required for blasting the target region is predicted according to the correlation between the preset geological parameter and the preset vibration intensity, the target calculation model, and the target region parameter of the region to be blasted. The target region parameter at least includes the target geological parameter of the region to be blasted.

[0062] In an embodiment, the correlation between the preset geological parameter and the preset vibration intensity can be set in advance according to actual conditions, and no detailed description is made. The preset vibration intensity can be considered as the vibration intensity required for the explosive to generate when blasting the ore rock composed of the preset geological parameter. For example, the vibration intensity required for blasting the rock body with different geological parameters can be determined according to the known failure criterion of jointed rock mass.

[0063] It should be noted that the explosion point of the explosive is usually set in the region to be blasted. Therefore, when the blasting region is smaller than the preset region area, the R value (the first distance) in the formula corresponding to each of the various first vibration intensities can be considered as 0. The preset region area can be set according to actual conditions, and no limitation is made.

[0064] Therefore, after the target geological parameter of the region to be blasted and the target vibration intensity corresponding to the target geological parameter are determined according to the correlation between the preset geological parameter and the preset vibration intensity, the target geological parameter and the target vibration intensity can be introduced into the above formula to obtain the target explosive amount.

[0065] However, the range of the region to be blasted is usually larger than the preset region area. Therefore, if the first distance is determined as 0, the target explosive amount obtained may not have a good blasting effect on the region to be blasted.

[0066] Therefore, in order to reasonably determine the target explosive quantity, the blasting explosive quantity determination device can determine a critical point farthest from the preset blasting point in the blasting area, and then obtain a target distance between the preset blasting point and the critical point. Then, according to the correlation between the preset geological parameters and the preset vibration intensity, a target vibration intensity corresponding to a target geological parameter of the blasting area is determined, so as to introduce the target geological parameter, the target vibration intensity and the target distance into the target calculation model to obtain the target explosive quantity.

[0067] 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.

[0068] In this embodiment, because the critical point is farthest from the preset blasting point, when the predicted target explosive quantity is blasted at the preset blasting point, the target vibration intensity generated thereby will be sufficient to destroy the ore rock at the critical point, so as to avoid repeated blasting of the blasting area.

[0069] In this embodiment, after the first distance between the blasting vibration instrument and each blasting point and the first geological parameter of each blasting point are determined, the first vibration intensity generated when each blasting point is blasted with different first explosive quantity is collected. Then, according to the first monitoring parameter and the first vibration parameter, a target calculation model for representing the factor relationship between the first vibration intensity and the first geological parameter and the first explosive quantity is generated. Then, according to the correlation between the preset geological parameters and the preset vibration intensity, the target calculation model and the target area parameter of the blasting area, the target explosive quantity required for blasting the blasting area is determined. In this way, according to the actual target geological parameter of the blasting area and the target calculation model obtained by theoretical calculation, a reasonable target explosive quantity can be determined, and the blasting effect of the blasting area can be optimized.

[0070] In another embodiment, in order to improve the accuracy of the determined target explosive quantity, when the first vibration parameter of each blasting point is collected by the blasting vibration instrument, the blasting vibration instrument needs to be processed, and the waveform collected by the blasting vibration instrument needs to be processed, so as to obtain a first vibration parameter with higher accuracy.

[0071] Specifically, the blasting explosive quantity determination device can determine the monitoring position of the blasting vibration instrument, and then determine the vibration source direction generated when the explosive is blasted according to the monitoring position and the position of the blasting point. Then, the target detection direction of the sensor in the blasting vibration instrument is set according to the vibration source direction.

[0072] In an embodiment, the sensor includes, but is not limited to, a vibration acceleration and a vibration speed of a vibration wave at a monitoring position, and an instrument for monitoring parameters such as pressure, temperature and humidity at the monitoring position.

[0073] The target detection direction of the sensor is generally one of the preset x, y, z and the like in the sensor. In the prior art, the detected data may be different when the sensor is located at different azimuth angles of the object to be detected, which may be caused by the difference in the azimuth between the sensing surface of the sensor and the object.

[0074] Therefore, in order to obtain the first vibration parameter with higher precision, the transmission direction of the vibration wave generated by the explosive blasting can be determined first, i.e., the vibration source azimuth from the blasting point to the monitoring position. Then, any one of the x, y and z coordinate axes in the detection direction of the sensor is set to be the same as the vibration source direction. In this embodiment, the x coordinate axis in the sensor can be set as the target detection direction.

[0075] The vibration source direction can be considered as the transmission direction of the vibration wave generated by the explosive blasting (from the blasting point to the monitoring position).

[0076] In another embodiment, in order to further obtain the first vibration parameter with higher precision, after the target detection direction of the sensor in the blasting vibration instrument is set according to the vibration source azimuth, the blasting explosive quantity determination device can first obtain the vibration waveform generated by the blasting at each blasting point collected by the blasting vibration instrument. Then, for any vibration waveform, the waveform in the target detection direction in the vibration waveform is separated to obtain the first vibration parameter.

[0077] It can be understood that the target detection direction of the sensor includes the x, y and z coordinate axes. Therefore, the vibration waveform finally collected by the sensor is also combined by the vibration waves in the three coordinate axes. However, since the x coordinate axis in the sensor is the target detection direction, it is the same as the transmission direction of the vibration wave generated by the explosive blasting, so it can be considered that the waveform in the x direction in the vibration waveform collected by the sensor can more accurately represent the first vibration parameter. That is, the waveform in the target detection direction in the vibration waveform is separated by the waveform analysis tool to obtain the first vibration parameter.
