It is to be understood that these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of these exemplary embodiments to those skilled in the art.
In this embodiment, a static load detection method for a mine is provided, as shown in fig. 1, the method includes:
110, acquiring the detonation time of a blasting device and the starting time period of a vibration acquisition device which are arranged in a target area;
the detonation moment is used for controlling the starting of the detonation device of the blasting device, the starting time period is used for controlling the vibration acquisition device to acquire data, and the starting time period comprises the starting moment and the ending moment. The initiation time and the initiation period may be manually entered by the user or may be automatically configured by a program.
In an actual application scenario, step 110, namely acquiring the detonation time of the blasting device arranged in the target area and the starting time period of the vibration acquisition device, specifically includes the following steps:
step 111, acquiring the starting time of the blasting device, the buffering time of the detonation component, the detonation delay time of the detonation component, the pre-starting time of the vibration acquisition device and the acquisition time of the vibration acquisition device;
the starting time is the time for the user to detonate the blasting device, for example, the time for the user to click the detonation button, the buffering time is the time required for information transmission between the detonation component and the computer device, and the buffering time of the detonation component can be set reasonably according to network parameters and communication parameters of the computer device and the detonation component, for example, the more serious the network delay, the longer the buffering time. The detonation delay time length is a delayed detonation time length of the blasting device required by a user, for example, the detonation delay time length is set to 0s, 60s, 200s and the like, when the detonation delay time length is 0, the blasting device does not perform delayed detonation, and when the detonation delay time length is not 0, the blasting device explodes after the buffering time length and the detonation delay time length by taking the detonation time as an initial time.
Step 112, determining the detonation moment of the blasting device according to the starting moment, the buffering duration and the detonation delay duration;
in the embodiment, in order to accurately determine the detonation time of the blasting device in consideration of the delay problem of data output in the information interaction process between the computer device for remote control and the detonation component, the starting time is adjusted according to the buffering time length and the detonation delay time length to obtain the final detonation time of the blasting device.
Step 113, determining the starting time of the vibration acquisition device according to the detonation time and the pre-starting time;
the pre-starting duration is used for indicating the time that the vibration acquisition device is ahead of the detonation of the blasting device.
And step 114, determining the ending time of the vibration acquisition device according to the detonation time and the acquisition time.
E.g. T Is opened ＝T-t s ，T Close off ＝T+t f In the formula, T Is opened Indicating the moment of opening, T Close off Indicating the end time, T the detonation time, T s Indicating a pre-start time period, t f Indicating the acquisition time period. The start-up period is T Is opened ,T Close off ]。
The pre-starting time length can be reasonably set according to the equipment parameters of the vibration acquisition device, and the acquisition time length can be reasonably set according to the historical vibration time length of the blasting device. In the case where the number of blasting devices is plural, the buffering time periods of different blasting devices may be the same or different, and similarly, the initiation delay time periods of different blasting devices may be the same or different.
It can be understood that, in order to achieve more comprehensive vibration information acquisition, the number of the vibration acquisition devices may also be multiple, and the starting time periods of the multiple vibration acquisition devices may be the same or different. For example, before one blasting device explodes, all the vibration acquisition devices are started simultaneously to acquire vibration information of the blasting device, and after the acquisition is finished, the vibration acquisition devices are closed simultaneously until the next blasting device explodes. Or after the first blasting device explodes, the vibration acquisition device close to the first blasting device is started to acquire vibration information of the first blasting device, the vibration acquisition device far away from the first blasting device maintains the shutdown state, the vibration acquisition device closes after the acquisition is finished, the vibration acquisition device close to the third blasting device starts to acquire the vibration information after the third blasting device explodes, and the vibration acquisition device far away from the third blasting device maintains the shutdown state.
In the embodiment, the final detonation moment of the blasting device is used as a basis for determining the starting time period of the vibration acquisition device, so that the vibration acquisition device can acquire vibration information just during the vibration generation of the blasting device, the service life loss and the resource waste caused by the long-time working state of the vibration acquisition device are avoided, and the reduction of the running cost of the vibration acquisition device is facilitated. Furthermore, because the vibration acquisition device may have a detection sensitivity error in the early stage of starting, the pre-starting time is set for the vibration acquisition device in advance, so that the vibration acquisition device controlled at the starting time obtained by calculating the pre-starting time can be started before the blasting device, the delay problem caused by unsmooth underground communication can be avoided, and the initiation time interval of each blasting device and the acquisition starting time interval of each vibration acquisition device cannot be influenced even if network communication delays. Not only guaranteed the complete vibrations information that produces when the explosion of the explosive device that vibrations collection system can gather, reserved sufficient start-up time for vibrations collection system moreover, improved vibrations collection system's the data acquisition degree of accuracy, and then improved follow-up static load analysis's accuracy.
In a possible embodiment, the number of the blasting devices may be m, where m is a positive integer greater than 1, and step 112 specifically includes the following steps:
112-1, determining the distance between two adjacent blasting devices in the m blasting devices according to the position information of the m blasting devices;
112-2, determining the detonation interval duration between two adjacent blasting devices according to the distance;
112-3, determining the detonation moment of the first blasting device according to the starting moment, the buffering duration and the detonation delay duration of the first blasting device;
and 112-4, calculating the detonation time of the nth blasting device according to the detonation time and the detonation interval duration of the first blasting device.
Wherein n is greater than 1 and less than or equal to m.
In this embodiment, the distance between two adjacent blasting devices is determined in advance by the position information uploaded by the m blasting devices. The detonation interval duration suitable for two adjacent blasting devices is matched through the distance. And determining the initiation time of the first blasting device to be initiated (the first blasting device), the buffering time and the initiation delay time. And calculating the detonation time of the nth blasting device according to n times of the detonation interval time length on the basis of the detonation time of the first blasting device. Thereby can carry out the design of blasting moment and collection period according to blasting unit's positional information is automatic, when having realized automatic parameter configuration, the accuracy of assurance time setting to in gather vibrations information, especially under the more condition of blasting unit quantity, effectively reduce the human consumption, help promoting dead load detection efficiency.
Specifically, for example, the computer device sets the detonation time of each blasting device according to the position information of each blasting device, and communicates with the downhole communication device, specifically, the number of the blasting devices is m, that is, m times of blasting needs to be performed, and the detonation time of each time is: t is 0 +Δt+Δt 1 ，T 0 +Δt+2×Δt 1 ，…，T 0 +Δt+m×Δt 1 . Wherein, T 0 Setting the starting time for the ground computer equipment, wherein delta t is the buffering time (buffering duration) after the detonation component receives the signal, and delta t 1 The initiation delay time of the blasting device is the same for the m times of blasting. And after determining the detonation moment, the computer equipment sends the detonation moment to the detonation components of the blasting devices, and after the detonation component successfully assigns the detonation moment, the computer equipment feeds back information of successful assignment to the computer equipment on the ground, so that the computer equipment can know that the detonation moment of the blasting devices is successfully set.
Similarly, the computer equipment on ground sets for the collection period of each vibration acquisition device according to the detonation moment of each blasting device, specifically, each blasting all needs to collect vibration information, that is, vibration information collection is divided into m times to be carried out, the collection period is divided into collection opening time and collection ending time, and the collection starting time of each collection is respectively: t is 0 +Δt+Δt 1 -t s ，T 0 +Δt+2×Δt 1 -t s ，…，T 0 +Δt+m×Δt 1 -t s (ii) a At each acquisitionThe collection end time is respectively as follows: t is 0 +Δt+Δt 1 +t f ，T 0 +Δt+2×Δt 1 +t f ，…，
T 0 +Δt+m×Δt 1 +t f (ii) a Wherein, t s To acquire the advance time (pre-start duration), t f Is the acquisition duration (acquisition duration).
the vibration information comprises a vibration waveform, and the vibration waveform can show information such as vibration speed, vibration frequency, vibration duration and the like.
In this embodiment, after acquiring the detonation time of the blasting device and the start time period of the vibration acquisition device, the computer device sends the detonation time and the start time period to the blasting device and the vibration acquisition device, respectively. And after the detonation component of the blasting device receives the detonation moment indicated by the computer equipment, igniting a blasting structure in the blasting device according to the detonation moment so as to explode the blasting device. And the vibration acquisition device is started according to the starting time interval to acquire vibration information generated by the blasting device. Thereby through computer equipment and blasting unit and vibrations collection system's information real-time interaction, realized blasting unit and vibrations collection system's remote control and data acquisition, need not artifical borehole and survey, can greatly reduced human cost to data acquisition's security has been compromise.
It should be noted that, before controlling the detonation of the blasting device and the collection of the vibration collection device, the computer device may send detection signals to the vibration collection device and the blasting device to determine whether the blasting device and the vibration collection device have been connected to the communication network, and in the case of determining that the blasting device and the vibration collection device can be in communication connection with the computer device. The detonation component and the vibration acquisition device are triggered to start by respectively sending the detonation moment and the starting time period to the detonation component and the vibration acquisition device, and then the reliability of subsequent remote control is ensured.
And 140, processing the vibration information to determine static load distribution information of the target area.
In this embodiment, the static load distribution information of the target area is determined by intensity analysis of the vibration information. The static load condition of a target area can be intuitively known by a user, so that the static load of coal mine induced rock burst can be eliminated from the source and fundamentally, the dangerous work efficiency of a working face is improved by developing a targeted static load pressure relief construction mode, the whole coal and rock mass of the area is in a stress environment with a low level, and the safety and the work efficiency of field personnel are effectively improved.
Specifically, for example, after the computer device determines the starting time period, the starting time period is sent to each vibration acquisition device through the underground communication device, and the vibration acquisition devices feed back information of successful assignment to the ground computer device after successful assignment of the starting time period. And after receiving the signals of successful assignment fed back by all the blasting devices and the vibration acquisition devices, the computer equipment sends a starting instruction to the blasting devices and the vibration acquisition devices through the underground communication device. And after receiving the starting instruction, the blasting device indexes the blasting explosive through detonating according to the assigned detonation moment. And the vibration acquisition device starts to acquire vibration information according to the starting time of the assignment after receiving the starting instruction, stops acquiring according to the finishing time of the assignment and transmits the vibration information to the computer equipment through the underground communication device. After receiving the vibration information, the computer device screens the effective waveforms in the vibration information and automatically stores files of the effective waveforms, and the file names can be the detonation time of the current detonation. After the computer equipment receives the vibration information of the last blasting device, all the received vibration information is analyzed through the information processing and visualization module, and the distribution state and the image of the coal rock mass static load can be obtained through inversion.
In some possible embodiments, step 140, namely, processing the vibration information to determine the static load distribution information of the target area, specifically includes: intercepting the vibration information, and determining a vibration waveform in the vibration information; carrying out exception elimination processing on the vibration waveform; and analyzing and processing the vibration waveform after the abnormality elimination processing to determine the static load distribution information of the target area.
In this embodiment, it is possible that some of the shock information may not be analytically valuable, considering that the shock-collecting device will be activated prior to the initiation moment of the blasting device. In order to reduce the detection error of the static load, after the vibration information is obtained, the vibration information can be automatically intercepted, and the section with the blasting waveform is screened. Further, exception eliminating processing is carried out on the screened blasting waveforms, so that exception data are deleted, and the detection accuracy of subsequent static load distribution information is guaranteed. For example, the vibration intensity should be gradually decreased with the passage of time, and if a time point with a high vibration intensity is suddenly appeared in the attenuation process, which indicates that there may be an abnormality in the time point data, the data is deleted.
It is worth mentioning that, taking the wave velocity of the vibration waveform as an example, the higher the wave velocity, the higher the static load level it is subjected to, the higher the impact risk.
Further, as a refinement and an extension of the specific implementation of the above embodiment, in order to fully describe the specific implementation process of the embodiment, step 140, that is, processing the vibration information, specifically includes: detecting the blasting state of the blasting device; and if the blasting device is determined to be in the blasted state, processing the vibration information of the blasting device in the blasted state.
In this embodiment, the blasting state of the blasting device is detected when the current moment reaches the blasting moment of the blasting device, that is, after the blasting device is detonated. If the fact that the blasting device is not detonated is detected, the corresponding vibration information cannot accurately reflect static load distribution, therefore, the vibration information of the blasting device is deleted, and only the vibration information of the blasting device which is successfully detonated is used as a static load analysis basis, so that static load analysis errors are reduced as much as possible through data screening, and the accuracy of static load detection is improved.
It is understood that the vibration information of the blasters in the blasted state may be processed after one blaster is detonated, or the vibration information of all blasters in the blasted state may be processed uniformly after all blasters are detonated.
It is worth mentioning that the computer device can display the blasting state after detecting the blasting state of the blasting device, so that the user can intuitively perceive whether the blasting device detonates.
Further, as a refinement and an extension of the specific implementation of the above embodiment, in order to fully describe the specific implementation process of the embodiment, in the case that the blasting state of the blasting device is detected, the mining static load detection method further includes: and if the blasting device is determined to be in the non-blasting state, outputting the position information of the blasting device in the non-blasting state.
In this embodiment, if it is detected that the blasting device is in an unexploded state, which indicates that the blasting device fails to detonate, the blasting device is determined to be a dummy gun, and the position information of the blasting device is output, so that the dummy gun is manually removed, damage to subsequent constructors by the residual blasting device is avoided, and safety of mine development is improved.
In an actual application scene, the detection mode for detecting the blasting state of the blasting device can be that a detection signal is sent to the blasting device through the communication device, the structure of the blasting device is damaged due to the explosion of the blasting device, and if information fed back by the blasting device is not received after a preset time length, the blasting device is indicated to be successfully detonated; whether the blasting device is successfully detonated or not can be judged according to the magnitude of the vibration information, and if no obvious vibration waveform exists in the vibration information, the detonation failure of the blasting device is indicated. It can be understood that the reason why the blasting device is not blasted can be further analyzed according to the blasting state of the blasting device. For example, if the information fed back by the blasting device is received and no obvious vibration waveform exists in the vibration information, the failure caused by the failure of the blasting device can be caused; if the information fed back by the blasting device is not received after the preset time length and no obvious vibration waveform exists in the vibration information, communication interruption of the blasting device may occur, that is, failure caused by communication failure of the blasting device may occur. Therefore, the method assists a user to quickly locate the abnormal reason and is convenient for deploying and controlling the subsequent blasting device.

step 210, receiving position information sent by a blasting device and a vibration acquisition device;
220, checking the position information of the blasting device and the position information of the vibration acquisition device;
and 230, outputting the position verification results of the blasting device and the vibration acquisition device.
In this embodiment, between blasting, through comparing the positional information of the blasting device and the vibration acquisition device and the arrangement positions of the preset blasting device and the vibration acquisition device, the position of the blasting device and the position of the vibration acquisition device are checked, and a position checking result is output. If the position information is consistent with the arrangement position, namely the verification is successful, the subsequent blasting and acquisition operation can be continuously carried out; otherwise, the user can in time adjust blasting unit and vibrations collection system to improve this control accuracy of blasting.
Further, as a refinement and an extension of the specific implementation of the above embodiment, in order to fully describe the specific implementation process of the embodiment, the mining static load detection method further includes:
step 310, determining first time information;
step 320, receiving second time information sent by the blasting device and/or the vibration acquisition device;
the first time information is time information recorded by computer equipment of the control end, and the second time information is time information recorded by the blasting device and/or the vibration acquisition device. The first time information or the second time information includes information for time measurement such as the current time, the time zone in which the time is located, and the like.
And 330, if the time difference between the first time information and the second time information is greater than the preset time difference, transmitting the first time information to the blasting device and/or the vibration acquisition device.
In this embodiment, the computer device records the first time information in real time. Before the blasting device is started, the second recorded time information is sent to the computer equipment by the blasting device and the vibration acquisition device. And the computer equipment judges whether the time of the computer equipment, the blasting device and the vibration acquisition device is synchronous or not by comparing the first time information with the second time information. If the time difference between the first time information and the second time information is detected to be larger than the preset time difference, the fact that the computer equipment is timely different from the blasting device and/or the vibration collecting device is indicated, and time advance control is not facilitated. And sending the first time information to the blasting device and/or the vibration acquisition device so that the blasting device and/or the vibration acquisition device replace the second time information with the first time information. Therefore, the time synchronization effect is achieved, the remote control accuracy of the blasting device and the vibration acquisition device is improved, the static load detection efficiency is effectively improved while the safety and the accuracy of the static load detection are ensured, and reliable data support is provided for the coal mining of a follow-up target area.
For example, the computer device sends out a time check signal, the time check signal is sent to each blasting device and each vibration acquisition device through the downhole communication device, each blasting device and each vibration acquisition device feed back current second time information to the computer device through the clock unit, if the time difference is large, the computer device can send out first time information to a specific blasting device or each vibration acquisition device, after the specific blasting device or each vibration acquisition device receives the first time information, the specific blasting device or each vibration acquisition device assigns the first time information to the clock unit of the computer device and feeds the first time information back to the computer device, and if the time difference is still large, the computer device needs to be debugged repeatedly until the time is synchronous.
