Background Art

[0002] Throwing blasting and loosening blasting are two common forms of rock crushing in open-pit coal mines. Loosening blasting can crush rocks in situ and is generally used in conjunction with the electric shovel-truck process. While throwing blasting can crush rocks and throw part of the rocks directly into the spoil dump at the same time, reducing the amount of subsequent mining, transportation and disposal operations. It is generally used in conjunction with the dragline shovel dumping process.

[0037] In this embodiment, a method for determining perforation and casting blasting parameters running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0038] Figure 2 FIG. 1 is a flow chart of a method for determining perforation and blasting parameters according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0039] Step S201, using the throwing blasting design software to design the throwing blasting process, and obtaining initial design parameters, the initial design parameters including blasting parameters, charge structure, geological conditions of the throwing blasting area, step height, slope angle, coal seam height, and throwing range;

[0040] Specifically, the throw blasting design software is used to design the throw blasting process to obtain scientific and reasonable initial design parameters. These parameters provide data basis for subsequent throw blasting construction operations, ensure that the blasting effect meets the expectations, comprehensively consider the actual environmental conditions, and realize the simulation of the throw blasting effect.

[0041] Step S202, using a throwing effect simulation software to simulate blasting based on the above initial design parameters to obtain a simulation result of the throwing blasting;

[0042] Specifically, the blasting simulation software is used to obtain the simulation results and conduct equipotential line analysis and safety inspection to fully adjust the above initial design parameters, so as to achieve better blasting effect and provide a more accurate basis for the final construction work.

[0043] Furthermore, equipotential line analysis and safety inspections can predict the effect of the throw blasting design and the degree of compliance with construction requirements. When the effect is not ideal or does not meet the construction requirements, the throw blasting parameters, charging structure, connection method and other design indicators are repeatedly modified and adjusted until the ideal blasting effect is obtained and the construction requirements are met. The design data is then exported through the throw blasting design software, and the construction team performs construction work according to the design requirements.

[0044] Step S203, obtaining the actual test results of the above-mentioned throwing blasting, and performing vibration detection analysis on the above-mentioned throwing blasting based on the above-mentioned actual test results to obtain vibration analysis results, wherein the actual test results of the above-mentioned throwing blasting are obtained by performing actual field tests using the above-mentioned initial design parameters;

[0045] Specifically, field tests of throw blasting are carried out, and the test results are analyzed. The vibration, noise and effects of throw blasting are detected and analyzed. The construction is further adjusted based on the analysis results obtained from the field tests, which can better smooth out the differences between simulated blasting and actual blasting, thereby ensuring that the blasting project has less pollution.

[0046] The vibration detection and analysis of the above-mentioned throwing blasting is performed based on the above-mentioned real test results to obtain the vibration analysis results, including the following steps:

[0047] Step S301, setting a plurality of measuring points in the above-mentioned throwing blasting area, and determining the maximum particle vibration velocity of each of the above-mentioned measuring points according to the vertical, radial and lateral three-dimensional blasting particle vibration velocity of the ground surface at each of the above-mentioned measuring points, so as to obtain the blasting data of each of the above-mentioned measuring points when conducting the above-mentioned real field test;

[0048] Step S302, according to the above-mentioned blasting data of each of the above-mentioned measuring points when conducting the above-mentioned real field test, the blasting seismic wave analysis, blasting seismic spectrum analysis, blasting seismic duration analysis and blasting vibration intensity analysis of the above-mentioned throwing blasting are carried out in sequence, and the blasting seismic waveform diagram, blasting seismic spectrum diagram, blasting seismic duration analysis and blasting vibration intensity of the above-mentioned throwing blasting are obtained respectively, wherein the frequency corresponding to the maximum vibration speed on the above-mentioned blasting seismic waveform diagram is the main shock frequency, and the frequency corresponding to the highest amplitude in the above-mentioned blasting seismic spectrum diagram is the main frequency.

[0049] Specifically, the maximum particle vibration velocity represents the intensity of the blasting earthquake at the measuring point. The spectrum analysis of blasting earthquakes includes three aspects: the first is the frequency corresponding to the maximum vibration velocity on the waveform, which is called the main shock frequency; the second is the frequency corresponding to the highest amplitude in the spectrum analysis diagram, which is called the dominant frequency; and the third is the frequency range. Vibration detection analysis can effectively smooth out the deviation between simulated blasting and actual blasting, thereby achieving the function of less pollution in blasting engineering.

[0050] Furthermore, the frequency of the blasting seismic wave changes with time and is not a simple harmonic wave of a single frequency. Generally, the time interval between two adjacent peaks or two valleys at the maximum amplitude is taken as the period T, and its reciprocal is the main vibration frequency of the vibration waveform, that is, the frequency of the wave corresponding to the point where the maximum vibration intensity occurs on the test vibration waveform.

[0051] Frequency is also one of the main factors affecting vibration damage. Under the same vibration intensity conditions, the lower the frequency, the greater the destructive energy. At the same time, the natural frequency of the building is very low, generally around a few Hz. Low frequency is more likely to form resonance with the building, causing greater destructive energy. On the spectrum analysis chart, the frequency with the largest amplitude is the main frequency, which reflects the main component in the signal, also known as the fundamental frequency.

[0052] Among them, setting multiple measuring points in the above-mentioned throwing blasting area includes the following steps:

[0053] Step S401, arranging a plurality of first measuring points on the same step of the above-mentioned throwing blasting area, wherein the plurality of the first measuring points are located in a straight line in the east area of ​​the above-mentioned throwing blasting area, and the above-mentioned first measuring points are used to monitor the lateral blasting seismic intensity of the above-mentioned throwing blasting area and the change law of the above-mentioned blasting seismic intensity;

[0054] Step S402, arranging two second measuring points outside the fault within a preset range from the above-mentioned throwing blasting area, the above-mentioned second measuring points are used to monitor the influence of the above-mentioned fault on the blasting earthquake;

[0055] Step S403, arranging a plurality of third measuring points on the same line in the preset direction of the above-mentioned throwing blasting zone, and the above-mentioned third measuring points are used to monitor the influence of pre-cracks on blasting vibration under the condition of pre-cracks, the above-mentioned blasting seismic intensity and the changing law of the above-mentioned blasting seismic intensity.

[0056] Specifically, Figure 3 and Figure 4As shown, 12 measuring points are set in the throwing blasting area, and they are arranged in three parts: in order to determine the propagation law of the blasting seismic wave in the lateral direction of the blasting area, four measuring points are arranged on the same step on the southeast side of the blasting area. The four measuring points are in a straight line and are located lateral to the detonation direction of the blasting area. The measuring points are numbered 1#, 2#, 3#, and 4# respectively; in order to monitor the influence of faults on blasting seismic waves, two measuring points are arranged outside a fault at the rear side of the blasting area (west side of the blasting area), and the measuring points are numbered 5# and 6# respectively; in order to detect the influence of pre-cracks on blasting seismic waves and their propagation law, six measuring points are arranged on the same straight line at the rear of the blasting area, and the measuring points are numbered 7#, 8#, 9#, 10#, 11#, and 12# respectively. These measuring points are arranged on different steps respectively.

[0057] The center position data of the 12 measuring points are shown in Table 1, where the throwing blasting area is the center of the blasting area:

[0058] Table 1. Measurement point center position

[0059]

[0060]

[0061] The method of determining the maximum particle vibration velocity of each of the above-mentioned measuring points according to the vertical, radial and lateral three-dimensional blasting particle vibration velocity of the ground surface at each of the above-mentioned measuring points comprises the following steps:

[0062] Step S501, using a blasting vibration recorder to detect the orthogonal components of the above-mentioned measuring point at each time in the first period in the vertical, radial and lateral directions of the above-mentioned surface, and obtain the vertical component, radial component and lateral component of the above-mentioned measuring point corresponding to each time;

[0063] Step S502, according to the vector sum of the maximum vertical component, the maximum radial component and the maximum transverse component in the first time period, the maximum particle vibration velocity of the measuring point is calculated, or the vertical component, the radial component and the transverse component of the measuring point in the first time period are respectively vector synthesized to obtain the vertical component vector sum, the radial component vector sum and the transverse component vector sum, and the maximum value among the vertical component vector sum, the radial component vector sum and the transverse component vector sum is determined as the maximum particle vibration velocity of the measuring point.

[0064] Specifically, the intensity of the blasting seismic wave changes with time and is a function of time. The same measuring point needs to test three orthogonal components, and the maximum value of their vector sum, that is, the maximum particle vibration velocity, represents the intensity of the blasting earthquake at the measuring point, thereby obtaining the influence of the intensity of the blasting seismic wave on the blasting effect.

[0065] The maximum particle vibration velocity is calculated by the vector sum of the maximum values ​​of the three components, which is called the maximum resultant velocity. However, since the maximum values ​​of the three components at the same measuring point do not occur at the same time, the calculated value obtained by the above method is higher than the actual value, which is safer from a safety perspective, but it more or less restricts the selection of the maximum charge volume for a blasting project.

[0066] Another method is to perform vector synthesis on the three components of the same measuring point point by point, and take the largest value to represent the maximum particle vibration velocity. This calculation is accurate and reasonable, and the vector resultant velocity is close to the axial maximum value, and the time of occurrence of the two is basically close. It can be seen from Table 2 that in the first throwing blasting, the vector resultant velocity of the blasting earthquake at the 1# measuring point at 574.9m lateral is 30.3mm / s, and the maximum resultant velocity is 43.0mm / s, which is equivalent to a Richter magnitude of 4.9; similarly, the vector resultant velocity of the blasting earthquake at the 4# measuring point is 10.3mm / s, and the maximum resultant velocity is 12.4mm / s, which is equivalent to a Richter magnitude of 3.7.

[0068]

[0069] According to the blasting data of each of the measuring points during the real field test, the blasting earthquake duration analysis of the throw blasting is performed to obtain the blasting earthquake duration of the throw blasting, including the following steps:

[0070] Step S601, determining the maximum amplitude of the waveform in the blasting seismic waveform diagram of the throw blasting according to the blasting data of each of the measuring points when the real field test is performed;

[0071] Step S602, according to the maximum amplitude of the waveform in the blasting seismic waveform diagram of the above-mentioned throwing blasting, determine the second time period as the duration of the blasting seismic of the above-mentioned throwing blasting, wherein the starting time of the above-mentioned second time period is the time corresponding to the amplitude μA, and the end time of the above-mentioned second time period is the time corresponding to the amplitude -μA, A is the maximum amplitude of the waveform in the blasting seismic waveform diagram of the above-mentioned throwing blasting, and μ is the coefficient.

[0072] Specifically, the duration of blasting earthquake refers to the time interval from the start to the stop of vibration at the measuring point. Since the sensitivity of the test system has a certain influence on the duration, a test system with high sensitivity will record a longer time, and vice versa. The duration of blasting earthquake can be used as a damage criterion to judge the size of the public nuisance of the blasting project.

[0073] Furthermore, the starting time of the second period is the time corresponding to the amplitude μA, and the ending time of the second period is the time corresponding to the amplitude -μA. This time interval is the duration of the blasting vibration, where the coefficient μ is usually taken as μ = (1 / 5 ~ 1 / 3). According to basic theory, under the same vibration intensity, the longer the duration, the greater the destructive power. Therefore, when evaluating the hazards of blasting vibration to buildings, in addition to using vibration intensity (displacement, velocity or acceleration) as a damage criterion, the cumulative destructive effect of the duration of blasting vibration on buildings should also be considered. This is also one of the main differences between blasting earthquakes and natural earthquakes. Natural earthquakes last longer, generally more than ten seconds, while blasting earthquakes last shorter, generally a few seconds. In the first throwing blasting test, the duration of blasting vibrations at some measuring points calculated according to μ = 1 / 5 is given in Table 3:

[0074] Table 3. Duration of blasting vibration at some measuring points during the first throwing blast

[0075]

[0076]

[0077] The duration of the blasting earthquake was close to 3 seconds, among which the average axial duration was relatively short at 2.662 seconds; the vertical and lateral durations were relatively close, the former was 2.974 seconds and the latter was 2.976 seconds.

[0078] According to the blasting data of each of the above-mentioned measuring points during the real field test, the blasting vibration intensity analysis of the above-mentioned throwing blasting is performed to obtain the blasting vibration intensity of the above-mentioned throwing blasting, including: according to the blasting data of each of the above-mentioned measuring points during the real field test, the first formula and the second formula The blasting vibration intensity of the above-mentioned throwing blasting is analyzed to obtain the blasting vibration intensity of the above-mentioned throwing blasting, wherein v is the particle vibration velocity, Q is the amount of explosives, R is the center distance from the measuring point to the blasting source, K is the blasting vibration attenuation coefficient, a is the attenuation index, and X is the equivalent distance that characterizes the relative relationship between the amount of explosives and the distance from the blasting source.

[0079] Specifically, the blasting vibration intensity reflects the attenuation law of blasting vibration and can be used to measure the blasting effect and the public hazards of blasting projects.

[0080] Furthermore, the blasting vibration detection data was processed and regressed. The regression analysis method used the least square method, and the obtained fitting curve had a good correlation. Figure 5 and Figure 6 The regression curves of blasting vibration attenuation law at the rear and right sides of the blasting area are given respectively. Figure 5 and Figure 6The blasting vibration velocity attenuation formula is obtained, where the blasting vibration attenuation law at the rear side of the blasting area is as follows: The attenuation law of blasting vibration on the right side of the blasting area is as follows:

[0081] From the above blasting vibration attenuation law formula, it can be seen that the blasting vibration attenuation coefficient k at the rear side of the blasting area is 后 =91.5, attenuation index α 后 =1.33; blasting vibration attenuation coefficient k on the right side of the blasting area 右 =200.7, attenuation index α 右 =1.40. This characteristic parameter is obtained under the conditions of deep hole throwing blasting with a distance range of 100m to 1800m and a maximum explosive charge of 15000kg within 8ms.

[0082] In addition, there is a pre-splitting blasting zone on the back of the blasting area, and there is no pre-splitting blasting zone on the right side of the blasting area, and the terrain is flat. The above formula is generally applicable to the vibration evaluation of large-scale blasting in all directions in the Jungar open-pit mine area.

[0083] In an optional solution, the blasting seismic wave is a random signal, and its frequency analysis adopts Fourier transform. By Fourier transforming the test signal, the frequency range-spectrum diagram of the vibration signal is obtained. Figure 7 , Figure 8 , Fig. 9 , Fig.10 The spectrum analysis diagrams of the three orthogonal components of measuring points 2, 4, 9 and 10 in the first blasting test are given respectively, and the spectrum analysis results can be obtained: the vibration frequency of the throwing blasting is low, the frequency range is narrow, it is a low-frequency vibration, and there is basically no high-frequency component.

[0084] Step S204, predicting the data of the above-mentioned throwing blasting according to the above-mentioned simulation results and the above-mentioned vibration analysis results to obtain predicted blasting data, and adjusting the above-mentioned initial design parameters according to the above-mentioned predicted blasting data to obtain target blasting parameters, so that the above-mentioned predicted blasting data is within a preset range, and the above-mentioned predicted blasting data at least includes the vibration and noise of the above-mentioned throwing blasting.

[0085] Specifically, the initial design parameters are finally adjusted in combination with the simulation results and the vibration analysis results to obtain blasting design parameters that can achieve less pollution in blasting engineering, less vibration impact and higher blasting efficiency, so as to effectively carry out cast blasting mining operations.

[0086] Among them, the sound frequency range that the human ear can hear is 20Hz to 20000Hz. The sound below 20Hz is called infrasound, and the sound above 20000Hz is called ultrasonic wave, which enables the human ear to analyze the explosion noise.

[0087] Among them, the data of the above-mentioned throwing blasting are predicted according to the above-mentioned simulation results and the above-mentioned vibration analysis results to obtain predicted blasting data, including: calculating the data of the above-mentioned throwing blasting according to the above-mentioned simulation results and the above-mentioned vibration analysis results to obtain the effective throwing rate, unit consumption of explosives, inclination of blastholes and explosive performance of the above-mentioned throwing blasting, wherein the above-mentioned effective throwing rate is the ratio of the blasting volume of the part of the stripping step that is thrown into the goaf after the above-mentioned throwing blasting and does not need to be dumped during the dragline shovel dumping stripping and coal mining operations to the total explosive volume.

[0088] Specifically, the predicted blasting data include effective throwing rate, explosive consumption per unit, blasthole inclination and explosive performance. Obtaining these data can adjust the initial design parameters more comprehensively.

[0089] In addition, before the formal blasting construction, the present application also has a pre-splitting blasting step, specifically, a row of pre-splitting holes arranged on the excavation edge line are detonated before the main gun hole is blasted. The result of the blasting is that cracks are formed between adjacent holes of the pre-splitting holes, and the entire pre-splitting hole arrangement plane forms a fracture surface to weaken the propagation of seismic waves to the slope rock mass during the blasting of the main blasting area and block the cracks that develop outside the slope, making the slope neat and increasing the stability of the slope. Based on the results of the above blasting vibration data analysis, it can be known that the vibration intensity of the blasting vibration wave is actually halved when passing through the pre-splitting blasting belt, indicating that the pre-splitting blasting belt plays an important shock-absorbing role. From this, the blasting vibration velocity values ​​in different directions can be calculated in reverse, or when calculating the maximum amount of explosives at one time, it is appropriate to divide it by a certain safety factor. In addition, the data of the measuring points on both sides of the fault show that the fault fracture zone has a significant attenuation effect on the blasting vibration.
