However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0071] This embodiment provides a method for detecting static loads in mines, such as... Figure 1 As shown, the method includes:

[0072] Step 110: Obtain the detonation time of the blasting device deployed in the target area and the start-up time of the vibration acquisition device;

[0073] The detonation time is used to control the activation of the detonator of the blasting device, and the activation period is used to control the data acquisition by the vibration acquisition device. The activation period includes the start time and the end time. The detonation time and activation period can be manually entered by the user or configured automatically by the program.

[0074] In practical applications, step 110, which involves obtaining the detonation time of the blasting device deployed in the target area and the start-up time of the vibration acquisition device, specifically includes the following steps:

[0075] Step 111: Obtain the start-up time of the blasting device, the buffer time of the detonation component, the detonation delay time of the detonation component, the pre-start-up time of the vibration acquisition device, and the acquisition time of the vibration acquisition device.

[0076] The activation time refers to the time when the user initiates the detonation of the blasting device, such as the moment the user clicks the detonation button. The buffer time is the time required for information transmission between the detonation component and the computer equipment. The buffer time of the detonation component can be reasonably set according to network parameters and communication parameters between the computer equipment and the detonation component. For example, the more severe the network latency, the longer the buffer time. The detonation delay time is the delayed detonation time of the blasting device required by the user. For example, the detonation delay time can be set to 0s, 60s, 200s, etc. When the detonation delay time is 0, the blasting device does not perform delayed detonation. When the detonation delay time is not 0, the blasting device explodes after the initial detonation time, which is the buffer time and the detonation delay time.

[0077] Step 112: Determine the detonation time of the blasting device according to the activation time, buffer time, and detonation delay time;

[0078] In this embodiment, considering the data output delay problem that exists during the information interaction between the computer equipment used for remote control and the detonation component, in order to accurately determine the detonation time of the blasting device, the activation time is adjusted according to the buffer time and the detonation delay time to obtain the final detonation time of the blasting device.

[0079] Step 113: Determine the start time of the vibration acquisition device according to the detonation time and pre-start duration;

[0080] The pre-start time is used to indicate the time when the vibration acquisition device is detonated before the blasting device.

[0081] Step 114: Determine the end time of the vibration acquisition device according to the detonation time and the acquisition duration.

[0082] For example, T 开启 =Tt s T 关闭 =T+t f In the formula, T 开启 Indicates the start time, T 关闭 The time of termination is indicated by T, and the time of detonation is indicated by t. s Indicates the pre-startup duration, t f This indicates the data collection duration. Therefore, the start time period is [T].开启 ,T 关闭 ].

[0083] The pre-start duration can be reasonably set according to the equipment parameters of the vibration acquisition device, and the acquisition duration can be reasonably set according to the historical vibration duration of the blasting device. When there are multiple blasting devices, the buffer duration of different blasting devices can be the same or different. Similarly, the detonation delay duration of different blasting devices can also be the same or different.

[0084] Understandably, to achieve more comprehensive vibration data collection, multiple vibration acquisition devices can be used, and their activation times can be the same or different. For example, before a blasting device explodes, all vibration acquisition devices are activated simultaneously to collect vibration data from that device. After collection, the devices are simultaneously deactivated until the next blasting device explodes. Alternatively, after the first blasting device explodes, the vibration acquisition device closest to it is activated to collect its vibration data, while the device farther away remains inactive. After collection, the device is deactivated. After the third blasting device explodes, the device closest to it begins collecting vibration data, while the device farther away remains inactive.

[0085] In this embodiment, the final detonation time of the blasting device is used as the basis for determining the start-up time of the vibration acquisition device. This ensures that the vibration acquisition device can collect vibration information precisely during the period when the blasting device generates vibration, avoiding the lifespan loss and resource waste caused by the vibration acquisition device being in a working state for a long time, and helping to reduce the operating cost of the vibration acquisition device. Furthermore, since the vibration acquisition device may have sensitivity errors in the early stage of startup, a pre-start-up time is set for the vibration acquisition device. This allows the vibration acquisition device, controlled by the start-up time calculated by the pre-start-up time, to start before the blasting device. This avoids delay problems caused by poor downhole communication. Even if there is a delay in network communication, it will not affect the detonation time interval of each blasting device or the acquisition start-up time interval of each vibration acquisition device. This not only ensures that the vibration acquisition device can collect complete vibration information generated by the explosion of the blasting device, but also reserves sufficient start-up time for the vibration acquisition device, improving the data acquisition accuracy of the vibration acquisition device, and thus improving the accuracy of subsequent static load analysis.

[0086] In one possible embodiment, the number of explosive devices can be set to m, where m is a positive integer greater than 1. Then step 112 specifically includes the following steps:

[0087] Step 112-1: Determine the spacing between two adjacent blasting devices among the m blasting devices based on their location information;

[0088] Step 112-2: Determine the detonation interval between two adjacent blasting devices according to the spacing.

[0089] Step 112-3: Determine the detonation time of the first explosive device according to the activation time, buffer time, and detonation delay time of the first explosive device;

[0090] Step 112-4: Calculate the detonation time of the nth blasting device based on the detonation time and detonation interval of the first blasting device.

[0091] Where n is greater than 1 and less than or equal to m.

[0092] In this embodiment, the distance between two adjacent explosive devices is pre-determined using the location information uploaded by m explosive devices. This distance is then used to match a suitable detonation interval between the two adjacent explosive devices. The detonation time of the first explosive device (the first explosive device) is determined by its activation time, buffer time, and detonation delay time. Based on the detonation time of the first explosive device, the detonation time of the nth explosive device is calculated as n times the detonation interval. This allows for automatic design of the detonation time and data collection period based on the location information of the explosive devices, achieving automated parameter configuration while ensuring the accuracy of time settings. This facilitates the collection of vibration information, especially when there are a large number of explosive devices, effectively reducing manpower consumption and improving the efficiency of static load detection.

[0093] For a specific example, the computer equipment sets the detonation time for each blasting device based on its location information and transmits this information via the underground communication device. Specifically, there are m blasting devices, meaning m blasts are required. The detonation times for each blast are: T0 + Δt + Δt1, T0 + Δt + 2 × Δt1, ..., T0 + Δt + m × Δt1. Here, T0 is the activation time set by the ground computer equipment, Δt is the buffer time (buffer duration) after the detonating component receives the signal, and Δt1 is the detonation delay time of the blasting device. The detonation delay time is the same for all m blasts. After determining the detonation time, the computer equipment sends it to the detonating component of each blasting device. Once the detonating component successfully assigns the detonation time, it sends a success message back to the ground computer equipment. Thus, the computer equipment knows that the detonation time of the blasting device has been successfully set.

[0094] Similarly, the ground-based computer equipment sets the acquisition time period for each vibration acquisition device based on the detonation time of each blasting device. Specifically, vibration information needs to be acquired for each blast, meaning that vibration information acquisition is divided into m times. The acquisition time period is divided into acquisition start time and acquisition end time. The acquisition start time for each acquisition is: T0 + Δt + Δt1 - ts T0+Δt+2×Δt1-t s ..., T0+Δt+m×Δt1-t s The end time of each data collection is: T0 + Δt + Δt1 + t f ,T0+Δt+2×Δt1+t f , ...,

[0095] T0+Δt+m×Δt1+t f ; where t s To collect data advance time (pre-startup duration), t f The duration of data collection (collection time).

[0096] Step 120: Detonate the blasting device by controlling the detonation component of the blasting device according to the detonation time;

[0097] Step 130: Control the vibration acquisition device to collect vibration information generated by the blasting device according to the start-up time period;

[0098] The vibration information includes vibration waveforms, which can display information such as vibration speed, vibration frequency, and vibration duration.

[0099] In this embodiment, after acquiring the detonation time of the blasting device and the activation period of the vibration acquisition device, the computer device sends the detonation time and activation period to the blasting device and the vibration acquisition device, respectively. Upon receiving the detonation time indicated by the computer device, the detonation component of the blasting device ignites the blasting structure within the device, causing it to explode. The vibration acquisition device activates according to the activation period to collect vibration information generated by the blasting device. Thus, through real-time information interaction between the computer device and the blasting device and vibration acquisition device, remote control and data acquisition of both devices are achieved, eliminating the need for manual underground detection, significantly reducing labor costs, and ensuring data acquisition security.

[0100] It should be noted that before controlling the detonation of the blasting device and the data acquisition of the vibration monitoring device, the computer equipment can send detection signals to both the blasting device and the vibration monitoring device to determine whether they are connected to the communication network. If it is determined that the blasting device and the vibration monitoring device can communicate with the computer equipment, the detonation time and activation period are sent to the detonating component and the vibration monitoring device respectively to trigger their activation, thereby ensuring the reliability of subsequent remote control.

[0101] Step 140: Process the vibration information to determine the static load distribution information of the target area.

[0102] In this embodiment, the static load distribution information of the target area is determined by analyzing the intensity of vibration information. This allows users to intuitively understand the static load situation of the target area, enabling the elimination of static loads that induce rockbursts in coal mines from the source and fundamentally. By carrying out targeted static load relief construction methods, the efficiency of hazard mitigation work at the working face can be improved, ensuring that the coal and rock mass in the area is in a low-stress environment, effectively improving the safety and work efficiency of on-site personnel.

[0103] For a specific example, after the computer equipment determines the start-up time period, it sends the start-up time period to each vibration acquisition device via the underground communication device. The vibration acquisition devices, after successfully assigning the start-up time period, send a feedback message of successful assignment to the computer equipment on the surface. Upon receiving the successful assignment signals from all the blasting devices and vibration acquisition devices, the computer equipment issues a start command, simultaneously sending it to both the blasting devices and vibration acquisition devices via the underground communication device. Upon receiving the start command, the blasting device detonates the explosive according to the assigned detonation time. Upon receiving the start command, the vibration acquisition device begins acquiring vibration information according to the assigned start time and stops acquiring according to the assigned end time, transmitting the vibration information to the computer equipment via the underground communication device. After receiving the vibration information, the computer equipment filters out the valid waveforms and automatically saves a file containing these valid waveforms, named after the detonation time of this blast. After receiving the vibration information from the last blasting device, the computer equipment analyzes all the received vibration information through the information processing and visualization module, and inverts the distribution and image of the static load of the coal and rock mass.

[0104] In some possible embodiments, step 140, namely processing the vibration information to determine the static load distribution information of the target area, specifically includes: truncating the vibration information to determine the vibration waveform in the vibration information; performing anomaly removal processing on the vibration waveform; and analyzing the vibration waveform after anomaly removal processing to determine the static load distribution information of the target area.

[0105] In this embodiment, considering that the vibration acquisition device starts before the detonation of the blasting device, some vibration information may not be valuable for analysis. To reduce the detection error of static load, after obtaining the vibration information, the vibration information can be automatically truncated, and intervals with blasting waveforms can be selected. Furthermore, the selected blasting waveforms are subjected to anomaly elimination processing to delete abnormal data, thereby ensuring the accuracy of subsequent static load distribution information detection. For example, as time progresses, the vibration intensity should gradually decrease. If a time point with a suddenly high vibration intensity appears during the decay process, it indicates that the data at that time point may be abnormal, and the data at that point is deleted.

[0106] 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 bears, and the higher the impact risk.

[0107] Furthermore, as a refinement and extension of the specific implementation of the above embodiments, in order to fully explain the specific implementation process of this embodiment, step 140, that is, processing the vibration information, specifically includes: detecting the blasting state of the blasting device; if it is determined that the blasting device is in the blasted state, processing the vibration information of the blasting device in the blasted state.

[0108] In this embodiment, the detonation time of the blasting device is reached at the current moment, that is, after the blasting device is detonated, and the detonation status of the blasting device is detected. If it is detected that the blasting device has not been detonated, its corresponding vibration information cannot accurately reflect the static load distribution. Therefore, the vibration information of the blasting device is deleted, and only the vibration information of the successfully detonated blasting device is used as the basis for static load analysis. In this way, through data filtering, the error of static load analysis is reduced as much as possible, and the accuracy of static load detection is improved.

[0109] It is understandable that the vibration information of a single explosive device can be processed after it has been detonated, or the vibration information of all explosive devices in their detonated state can be processed uniformly after all explosive devices have been detonated.

[0110] It is worth mentioning that after the computer equipment detects the blasting status of the blasting device, it can display the blasting status so that users can intuitively perceive whether the blasting device has detonated.

[0111] Furthermore, as a refinement and extension of the specific implementation of the above embodiments, in order to fully illustrate the specific implementation process of this embodiment, when the blasting state of the blasting device is detected, the mining static load detection method further includes: if it is determined that the blasting device is in an unblasted state, outputting the position information of the blasting device in the unblasted state.

[0112] In this embodiment, if the blasting device is detected to be in an unexploded state, it indicates that the blasting device has failed to detonate, and the blasting device is determined to be a dud. The location information of the blasting device is then output to facilitate manual removal of the dud, thereby preventing residual blasting devices from causing harm to subsequent construction personnel and improving the safety of mine development.

[0113] In practical applications, the detection of the blasting status of a blasting device can be achieved by sending a detection signal to the device via a communication device. Since the explosion causes structural damage, if no feedback is received from the device after a preset time, it indicates successful detonation. Alternatively, the magnitude of vibration data can be used to determine successful detonation; if no obvious vibration waveform is observed, the device has failed to detonate. Understandably, the blasting status can be further analyzed to determine the cause of failure. For example, if feedback is received but no obvious vibration waveform is observed, the failure may be due to a malfunction in the detonator. If no feedback is received after a preset time and no obvious vibration waveform is observed, the failure may be due to a communication interruption, i.e., a communication failure. This helps users quickly locate the cause of the anomaly and facilitates the deployment of subsequent blasting devices.

[0114] Furthermore, as a refinement and extension of the specific implementation of the above embodiments, and in order to fully illustrate the specific implementation process of this embodiment, before step 120, the mine static load detection method further includes:

[0115] Step 210: Receive position information sent by the blasting device and the vibration acquisition device;

[0116] Step 220: Verify the location information of the blasting device and the location information of the vibration acquisition device;

[0117] Step 230: Output the position verification results of the blasting device and the vibration acquisition device.

[0118] In this embodiment, before blasting, the positions of the blasting device and the vibration acquisition device are compared with their preset placement positions to perform position verification, and the verification results are output. If the position information matches the placement positions, i.e., the verification is successful, subsequent blasting and acquisition operations can continue; otherwise, the user can adjust the blasting device and the vibration acquisition device in a timely manner, thereby improving the control accuracy of the blasting.

[0119] Furthermore, as a refinement and extension of the specific implementation of the above embodiments, and in order to fully illustrate the specific implementation process of this embodiment, the mine static load detection method further includes:

[0120] Step 310: Determine the first-time information;

[0121] Step 320: Receive second time information sent by the blasting device and / or vibration acquisition device;

[0122] The first time information refers to the time information recorded by the computer equipment at the control end, and the second time information refers to the time information recorded by the blasting device and / or vibration acquisition device. The first or second time information includes information used for timing, such as the current time and time zone.

[0123] Step 330: If the time difference between the first time information and the second time information is greater than the preset time difference, the first time information is sent to the blasting device and / or the vibration acquisition device.

[0124] In this embodiment, the computer device records first time information in real time. Before the blasting device is activated, the blasting device and the vibration acquisition device send the recorded second time information to the computer device. The computer device compares the first time information and the second time information to determine whether the computer device, the blasting device, and the vibration acquisition device are synchronized. If the time difference between the first time information and the second time information is detected to be greater than a preset time difference, it indicates that there is a time discrepancy between the computer device and the blasting device and / or the vibration acquisition device, which is detrimental to time accuracy control. In this case, the first time information is sent 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. This achieves time synchronization, helps improve the accuracy of remote control of the blasting device and the vibration acquisition device, and effectively improves the efficiency of static load detection while ensuring the safety and accuracy of static load detection, providing reliable data support for subsequent coal mining in the target area.

[0125] For example, the computer equipment sends a time verification signal, which is transmitted to each blasting device and each vibration acquisition device via the underground communication device. Each blasting device and vibration acquisition device feeds back the current second time information to the computer equipment through its clock unit. If there is a large time difference, the computer equipment can send the first time information to a specific blasting device or vibration acquisition device. After receiving the first time information, the specific blasting device or vibration acquisition device assigns the first time information to its own clock unit and feeds it back to the computer equipment. If the time difference is still large, repeated adjustments are required until the time is synchronized.

[0126] Furthermore, such as Figure 2 As shown, as a specific implementation of the above-mentioned mining static load detection method, this application provides a mining static load detection device 400, which includes: an acquisition module 401, a control module 402, and an analysis module 403.

[0130] In this embodiment, a blasting device and a vibration acquisition device with communication capabilities are pre-deployed at designated locations within the roadway of the target area. After acquiring the detonation time of the blasting device and the activation time of the vibration acquisition device, the computer equipment sends these times to the blasting device and the vibration acquisition device, respectively. Upon receiving the detonation time indicated by the computer equipment, the detonating component of the blasting device ignites the blasting structure within the device, causing it to explode. The vibration acquisition device activates according to the activation time to collect vibration information generated by the blasting device. The computer equipment can then analyze the static load distribution information of the target area using the vibration information sent by the vibration acquisition device. Thus, through real-time information interaction between the computer equipment and the blasting device and vibration acquisition device, remote control of both devices is achieved, eliminating the need for manual underground detection. This significantly reduces labor costs and, while ensuring the safety and accuracy of static load detection, effectively improves detection efficiency, providing reliable data support for subsequent coal mining in the target area.

[0132] Furthermore, the acquisition module 401 is specifically used to determine the distance between two adjacent blasting devices among the m blasting devices based on the position information of the m blasting devices, where m is a positive integer greater than 1; determine the detonation interval between two adjacent blasting devices according to the distance; determine the detonation time of the first blasting device according to the detonation time and buffer time of the first blasting device; and calculate the detonation time of the nth blasting device according to the detonation time and detonation interval of the first blasting device, where n is greater than 1 and less than or equal to m.

[0135] Furthermore, the mining static load detection device 400 also includes: a first communication module (not shown in the figure), which is used to receive position information sent by the blasting device and the vibration acquisition device; a verification module (not shown in the figure), which is used to verify the position information of the blasting device and the position information of the vibration acquisition device; and a second output module (not shown in the figure), which is used to output the position verification results of the blasting device and the vibration acquisition device.

[0136] Furthermore, the mining static load detection device 400 also includes: a timing module (not shown in the figure) for determining first time information; a second communication module (not shown in the figure) for receiving second time information sent by the blasting device and / or the vibration acquisition device; and, if the time difference between the first time information and the second time information is greater than a preset time difference, 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 replaces the second time information with the first time information.
