Description

Technical Field

[0001] The present invention relates to the technical field of water control in coal mines, and specifically to an intelligent monitoring and control method for geological survey and water control in coal mines. Background Technique

[0002] As an important energy source in China, coal occupies a key position in industrial production and economic development. However, coal mine exploitation operations often face complex hydrogeological conditions, and mine water hazards have always been major hidden dangers threatening the safety of coal mine production. In the past few decades, although the coal mine industry in China has made certain progress in water control technology, there are still many problems in traditional geological survey and water control work in coal mines.

[0003] On the one hand, the scheduling and regulation of drainage devices lack intelligence. In the face of sudden water hazards, errors and delays are likely to occur in the process of manually judging the location of water hazards and starting drainage devices, resulting in the inability to control water hazards in a timely manner. At the same time, drainage devices usually operate according to preset fixed parameters. After detecting water inrush, they immediately carry out operations according to the established drainage flow rate and duration, without dynamically adjusting the operating parameters of drainage devices in combination with actual situations such as the scale of water inrush, water pressure, and underground water level. If the drainage parameters are set too small, the accumulated water cannot be drained in time, which may lead to water accumulation and flooding in roadways, exacerbating the harm of water hazards; if the drainage parameters are set too large, it will not only cause excessive energy consumption and additional wear of equipment, but also increase the operating costs of coal mines. This lack of flexibility and intelligence in the control method is difficult to adapt to complex and changeable water hazard scenarios.

[0004] On the other hand, the current water control work seriously lacks a real-time monitoring and evaluation mechanism for drainage effects. It is impossible to grasp the actual drainage flow rate of drainage devices, the changes in accumulated water levels, and water quality conditions in real time, resulting in the inability to discover and take effective countermeasures in a timely manner when the drainage effect fails to meet expectations or drainage in some areas is not timely. This greatly weakens the reliability of water control work and cannot provide absolute safety guarantee for underground operations in coal mines.

[0005] To solve the above defects, a technical solution is provided now. Summary of the Invention

[0006] The purpose of the present invention is to provide an intelligent monitoring and control method for geological survey and water control in coal mines to solve the problems raised in the above background.

[0007] The purpose of the present invention can be achieved through the following technical solutions: An intelligent monitoring and control method for geological survey and water control in coal mines includes the following steps:

[0008] Step 1. Roadway area division and drainage device deployment: Divide the underground coal mine roadways according to the preset equal-area principle to obtain each underground coal mine roadway area, and set drainage devices on both sides of each underground coal mine roadway area.

[0009] Step 2. Hydrogeological disaster monitoring and identification: Obtain the geological structure information within each underground coal mine roadway area to get the distribution ranges of aquifers, aquicludes, and fault fracture zones within each underground coal mine roadway area, and obtain the hydrogeological disaster correlation information corresponding to each underground coal mine roadway area at each monitoring time point during the monitoring period. Then analyze the hydrogeological disaster risk situations of each underground coal mine roadway area, judge whether there are hydrogeological disaster risks in each underground coal mine roadway area, and locate the positions of each hydrogeological disaster source in the underground coal mine roadways.

[0010] Step 3. Operation drainage device scheduling: Obtain the drainage devices closest to the hydrogeological disaster sources on both sides of each hydrogeological disaster source area in the underground coal mine roadways, mark them as the left-side operation drainage device and the right-side operation drainage device for each hydrogeological disaster source area in the underground coal mine roadways, and control them to start.

[0011] Step 4. Operation drainage device regulation: Obtain the prevention and control parameters of the hydrogeological disaster sources detected by the left-side operation drainage device and the right-side operation drainage device during the prevention and control of each hydrogeological disaster source in the underground coal mine roadways, where the prevention and control parameters include water inflow rate, water pressure, water level, and water velocity. Analyze the reference drainage parameters of the left-side operation drainage device and the right-side operation drainage device for each hydrogeological disaster source, where the drainage parameters include drainage flow rate and drainage duration, and control the left-side operation drainage device and the right-side operation drainage device for each hydrogeological disaster source.

[0012] Step 5. Judgment of the drainage effect of the operation drainage device: Analyze the drainage effect coefficient of the operation drainage device corresponding to each hydrogeological disaster source to judge whether the drainage effect of the operation drainage device corresponding to each hydrogeological disaster source meets the requirements.

[0013] Step 6. Scheduling of auxiliary operation drainage device: When it is determined that the drainage effect of the left-side operation drainage device or the right-side operation drainage device corresponding to a certain hydrogeological disaster source does not meet the requirements, start the left-side auxiliary operation drainage device or the right-side auxiliary operation drainage device of each hydrogeological disaster source, and control it to start.

[0014] Step 7. Regulation of the auxiliary operation drainage device: Analyze the reference drainage parameters of the left-side auxiliary operation drainage device and the right-side auxiliary operation drainage device for each hydrogeological disaster source, and control the left-side auxiliary operation drainage device and the right-side auxiliary operation drainage device for each hydrogeological disaster source.

[0015] Preferably, the obtaining of the hydrological disaster correlation information of each coal mine underground roadway area corresponding to each monitoring time point within the monitoring period includes: obtaining the water-richness of the aquifer, the permeability of the aquifer, the thickness of the aquitard, and the water conductivity of the fault fracture zone in each coal mine underground roadway area corresponding to each monitoring time point within the monitoring period.

[0016] Preferably, the steps for analyzing the hydrological disaster risk situation of each coal mine underground roadway area are as follows:

[0017] According to the water-richness of the aquifer, the permeability of the aquifer, the thickness of the aquitard, and the water conductivity of the fault fracture zone in each coal mine underground roadway area corresponding to each monitoring time point within the monitoring period, obtain the maximum water-richness of the aquifer and the growth rate of the average water-richness of the aquifer, the maximum permeability of the aquifer and the growth rate of the average permeability of the aquifer, the minimum thickness of the aquitard, the maximum water conductivity of the fault fracture zone and the growth rate of the average water conductivity of the fault fracture zone within the monitoring period.

[0018] Extract the warning values of the water-richness of the aquifer, the permeability of the aquifer, the thickness of the aquitard, and the water conductivity of the fault fracture zone stored in the database, and accordingly analyze and obtain the influence index of the water-richness of the aquifer, the influence index of the permeability of the aquifer, the influence index of the thickness of the aquitard, and the influence index of the water conductivity of the fault fracture zone in each coal mine underground roadway.

[0019] Convert the influence index of the water-richness of the aquifer, the influence index of the permeability of the aquifer, and the influence index of the water conductivity of the fault fracture zone in each coal mine underground roadway into lengths according to a preset ratio. Respectively, take the length of the influence index of the water-richness of the aquifer as the length, the length of the influence index of the permeability of the aquifer as the width, and the length of the influence index of the water conductivity of the fault fracture zone as the height to construct a cuboid. Extract the numerical value of the volume of the cuboid as Result One, multiply it by the influence index of the thickness of the aquitard to obtain Result Two, and take Result Two as the hydrological disaster risk coefficient. Thus, statistically obtain the hydrological disaster risk coefficients of each coal mine underground roadway area.

[0020] Preferably, the steps for determining whether there is a hydrological disaster risk in each coal mine underground roadway area are as follows:

[0021] Compare the hydrological disaster risk coefficients of each coal mine underground roadway area with the preset hydrological disaster risk coefficient threshold. If the hydrological disaster risk coefficient of a certain coal mine underground roadway area is greater than or equal to the preset hydrological disaster risk coefficient threshold, it is determined that there is a hydrological disaster risk in that coal mine underground roadway area, and the coal mine underground roadway area with the hydrological disaster risk coefficient greater than or equal to the preset hydrological disaster risk coefficient threshold is recorded as an abnormal area.

[0022] If the hydrological disaster risk coefficient of a certain coal mine underground roadway area is less than the preset hydrological disaster risk coefficient threshold, it is determined that there is no hydrological disaster risk in that coal mine underground roadway area.

[0023] Preferably, the steps of locating the positions of various hydrogeological disaster sources in the coal mine underground roadway are as follows:

[0024] Number each coal mine underground roadway area, extract the hydrogeological disaster risk coefficients and corresponding numbers of each coal mine underground roadway area, count the number of abnormal areas, compare the numbers of each abnormal area, calculate the difference between the maximum number and the minimum number, compare the result of the difference calculation with the number of abnormal areas, and judge whether each abnormal area is a continuous area.

[0025] If it is judged to be a continuous area, then compare the hydrogeological disaster risk coefficients of each abnormal area, and select the abnormal area corresponding to the maximum hydrogeological disaster risk coefficient as the hydrogeological disaster source.

[0026] If it is judged not to be a continuous area, then obtain each continuous abnormal area and each discontinuous abnormal area, compare the hydrogeological disaster risk coefficients within each continuous abnormal area, select the abnormal area corresponding to the maximum hydrogeological disaster risk coefficient in each continuous abnormal area as the hydrogeological disaster source of this continuous abnormal area, and then count the numbers corresponding to the hydrogeological disaster sources of each continuous abnormal area. The coal mine underground roadway areas corresponding to the listed numbers are the hydrogeological disaster sources of the coal mine underground roadway. At the same time, for the numbers corresponding to the hydrogeological disaster sources of the discontinuous abnormal areas, the coal mine underground roadway areas corresponding to the listed numbers are the hydrogeological disaster sources of the coal mine underground roadway.

[0027] Thus, the positions of various hydrogeological disaster sources in the coal mine underground roadway are located.

[0028] Preferably, the steps of analyzing the reference drainage parameters of the drainage devices on the left and right sides of each hydrogeological disaster source are as follows:

[0029] Obtain the groundwater inflow rate, water pressure, water level and water velocity of the hydrogeological disaster sources detected by the drainage devices on the left and right sides of each hydrogeological disaster source in the coal mine underground roadway. Calculate the ratios of the groundwater inflow rate, water pressure, water level and water velocity of the hydrogeological disaster sources detected by the drainage devices on the left side of each hydrogeological disaster source in the coal mine underground roadway to their preset inflow rate threshold, water pressure threshold, water level threshold and water velocity threshold respectively to obtain the corresponding ratio results. Sum up the ratio results corresponding to the inflow rate, water pressure, water level and water velocity of the drainage devices on the left side of each hydrogeological disaster source in the coal mine underground roadway according to the weights to obtain the hydrogeological disaster severity coefficient detected by the drainage devices on the left side of each hydrogeological disaster source in the coal mine underground roadway.

[0030] Similarly, obtain the hydrogeological disaster severity coefficient detected by the drainage devices on the right side of each hydrogeological disaster source in the coal mine underground roadway.

[0031] Match the coefficients of the severity of hydrological disasters detected by the drainage devices for left-side operations of each hydrological disaster source in the underground roadway of the coal mine and the coefficients of the severity of hydrological disasters detected by the drainage devices for right-side operations with the reference drainage parameters of the drainage devices corresponding to the set coefficients of the severity of each hydrological disaster to obtain the reference drainage parameters of the drainage devices for left-side operations and the reference drainage parameters of the drainage devices for right-side operations of each hydrological disaster source in the underground roadway of the coal mine. Herein, the drainage parameters refer to the drainage flow rate and the drainage duration.

[0032] Preferably, the steps for analyzing the drainage effect coefficients of the drainage devices corresponding to each hydrological disaster source are as follows:

[0033] Extract the reference drainage parameters of the drainage devices for left-side operations and the reference drainage parameters of the drainage devices for right-side operations corresponding to each hydrological disaster source, and match them respectively with the standard groundwater level drop values corresponding to the reference drainage parameters of each drainage device stored in the database to obtain the standard groundwater level drop values of the drainage devices for left-side operations and the standard groundwater level drop values of the drainage devices for right-side operations corresponding to each hydrological disaster source.

[0034] Obtain the actual groundwater level drop value of the drainage device for left-side operations corresponding to each hydrological disaster source, calculate the ratio of it to the standard groundwater level drop value of the drainage device for left-side operations corresponding to each hydrological disaster source to obtain the drainage effect coefficient of the drainage device for left-side operations corresponding to each hydrological disaster source.

[0035] Similarly, obtain the drainage effect coefficients of the drainage devices for right-side operations corresponding to each hydrological disaster source.

[0036] Compare the drainage effect coefficients of the drainage devices for left-side operations corresponding to each hydrological disaster source with the preset drainage effect coefficient threshold. If the drainage effect coefficient of the drainage device for left-side operations corresponding to a certain hydrological disaster source is greater than or equal to the preset drainage effect coefficient threshold, it is determined that the drainage effect of the drainage device for left-side operations corresponding to this hydrological disaster source meets the requirements. If the drainage effect coefficient of the drainage device for left-side operations corresponding to a certain hydrological disaster source is less than the preset drainage effect coefficient threshold, it is determined that the drainage effect of the drainage device for left-side operations corresponding to this hydrological disaster source does not meet the requirements.

[0037] Similarly, determine whether the drainage effects of the drainage devices for right-side operations corresponding to each hydrological disaster source meet the requirements.

[0038] Preferably, the steps for analyzing the reference drainage parameters of the left-side auxiliary drainage devices and the right-side auxiliary drainage devices of each hydrological disaster source are as follows:

[0039] Calculate the difference between the drainage effect coefficient of the left-side operation drainage device of each hydro-hazard source and the preset drainage effect coefficient threshold to obtain the drainage effect coefficient difference of the left-side operation drainage device of each hydro-hazard source, and match it with the reference drainage parameters of the left-side auxiliary operation drainage device corresponding to the preset drainage effect coefficient difference of each left-side operation drainage device to obtain the reference drainage parameters of the left-side auxiliary operation drainage device of each hydro-hazard source.

[0040] Similarly, according to the analysis method of the reference drainage parameters of the left-side auxiliary operation drainage device of each hydro-hazard source, obtain the reference drainage parameters of the right-side auxiliary operation drainage device of each hydro-hazard source.

[0041] Advantages of the present invention:

[0042] By monitoring the water-richness of the aquifer, the permeability of the aquifer, the thickness of the aquitard, and the water conductivity of the fault fracture zone in the coal mine underground roadway, the present invention intelligently identifies the location of the hydro-hazard source in the coal mine underground roadway and activates the drainage device near the hydro-hazard source, reducing the error caused by human intervention, accurately judging the location where a hydro-hazard may occur and activating the corresponding drainage device, thereby avoiding or reducing the losses caused by hydro-hazards to a certain extent and ensuring the safety of coal mine underground operations.

[0043] By monitoring the groundwater inflow rate, water pressure, water level, and water velocity of each hydro-hazard source in the coal mine underground roadway, analyzing the reference drainage parameters of the operation drainage device of each hydro-hazard source, and performing corresponding control based on the reference drainage parameters, the present invention can adaptively adjust the drainage parameters of the drainage device in combination with the severity of the hydro-hazard source, improving the pertinence and effectiveness of the water control work in the coal mine underground roadway to a certain extent.

[0044] By monitoring the drainage effect of the operation drainage devices on both sides of the hydro-hazard source to judge whether it meets the requirements, if it does not meet the requirements, the auxiliary operation drainage devices on both sides of the hydro-hazard source are activated and adjusted, and their reference drainage parameters are analyzed and adjusted according to the actual situation, further enhancing the drainage capacity and ensuring effective drainage operations under various complex hydro-hazard conditions and guaranteeing the safety of the coal mine underground.

Detailed implementation manners

[0050] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0051] Please refer to Figures 1 - 3 As shown in the figure, the present invention is an intelligent monitoring and control method for geological survey and water prevention and control in coal mines, including the following steps:

[0052] Step 1. Division of roadway areas and deployment of drainage devices: The underground roadways in coal mines are divided into each underground roadway area in coal mines according to the preset equal-area principle, and drainage devices are arranged on both sides of each underground roadway area in coal mines.

[0053] Step 2. Monitoring and identification of hydrogeological disasters: Obtain the geological structure information in each underground roadway area in coal mines to obtain the distribution ranges of aquifers, aquitards and fault fracture zones in each underground roadway area in coal mines, and obtain the hydrogeological disaster correlation information corresponding to each monitoring time point in the monitoring period for each underground roadway area in coal mines, and then analyze the hydrogeological disaster risk situations in each underground roadway area in coal mines, and judge whether there are hydrogeological disaster risks in each underground roadway area in coal mines, and locate the positions of each hydrogeological disaster source in the underground roadways in coal mines.

[0054] As a preferred feasible embodiment, the obtaining of the hydrogeological disaster correlation information corresponding to each monitoring time point in the monitoring period for each underground roadway area in coal mines includes: obtaining the water richness of the aquifer, the permeability of the aquifer, the thickness of the aquitard, and the water conductivity of the fault fracture zone corresponding to each monitoring time point in the monitoring period for each underground roadway area in coal mines.

[0055] It should be noted that the obtaining methods of the water richness of the aquifer, the permeability of the aquifer, the thickness of the aquitard, and the water conductivity of the fault fracture zone are as follows:

[0056] Utilize the differences in the geophysical properties of different lithologies and water-bearing strata, measure the resistivity, spontaneous potential and acoustic velocity of the corresponding aquifer in the underground roadway of the coal mine through logging instruments, and then obtain the water richness of the aquifer according to the relationship function between the resistivity, spontaneous potential and acoustic velocity of the aquifer and the water richness of the aquifer.

[0057] The porosity distribution of the aquifer is obtained through nuclear magnetic resonance logging, and then the aquifer permeability is obtained according to the relationship function between porosity and aquifer permeability.

[0058] Through the geological structure profile in the geological structure information in the underground roadway area of the coal mine, the water - resisting layer interface is identified on the profile according to the characteristics of the reflected wave (such as the amplitude, frequency and phase of the reflected wave), and then the thickness of the water - resisting layer is determined by analyzing the continuity and distribution range of the reflected wave.

[0059] A pulsed current is emitted into the underground roadway area of the coal mine through the transmitting coil of the variometer. An alternating electromagnetic field is formed underground. When the electromagnetic field encounters geological bodies with different electromagnetic characteristics, a secondary induced electromagnetic field will be generated. The receiving coil receives these secondary field signals. The instrument records the electromagnetic signal intensity and characteristics at different times and positions. The collected electromagnetic data is processed and inverted to draw an electromagnetic response image of the underground geological body, and then the location of the fault fracture zone is determined. Then, according to the abnormal characteristics of the electromagnetic response (such as abnormal intensity, range, shape, etc.), the water - conducting property of the fault fracture zone is determined.

[0060] As a preferred feasible embodiment, the steps of analyzing the hydro - geological disaster risk situation in each underground roadway area of the coal mine are as follows:

[0061] According to the water - richness of the aquifer, the aquifer permeability, the thickness of the water - resisting layer, and the water - conducting property of the fault fracture zone in each underground roadway area of the coal mine corresponding to each monitoring time point within the monitoring period, the maximum water - richness of the aquifer and the growth rate of the average water - richness of the aquifer, the maximum aquifer permeability and the growth rate of the average aquifer permeability, the minimum thickness of the water - resisting layer, the maximum water - conducting property of the fault fracture zone and the growth rate of the average water - conducting property of the fault fracture zone within the monitoring period are obtained.

[0062] It should be noted that the reasons for selecting the water abundance of the aquifer, the permeability of the aquifer, the thickness of the aquitard, and the water conductivity of the fault fracture zone as the risk coefficients of the hydrogeological disasters in the underground coal mine roadways are as follows: 1. An aquifer with strong water abundance contains a large amount of water. Once there is a hydraulic connection with the roadway, there will be sufficient water sources flowing into the roadway, triggering water disasters. For example, in the case of a thick sandstone aquifer, if its water abundance is good, after the roadway excavation exposes it or the aquitard is damaged due to geological structures, a large amount of water will quickly flow in, resulting in the serious consequences of roadway waterlogging or even inundation. 2. Permeability determines the flow rate and ability of groundwater in the aquifer. In an aquifer with good permeability, water can quickly converge towards the roadway. Even if the water abundance of the aquifer is average, but with strong permeability, a large water inflow may be formed in a short time, increasing the possibility and degree of harm of hydrogeological disasters. 3. The aquitard plays a key role in blocking the infiltration of groundwater into the roadway. A thick aquitard can effectively prevent or slow down the flow of groundwater and reduce the risk of hydrogeological disasters. On the contrary, if the thickness of the aquitard is insufficient, it will be difficult to withstand the pressure of groundwater and is easily breached, leading to water disasters. 4. The fault fracture zone is often a channel for groundwater migration. If its water conductivity is strong, it will enhance the hydraulic connection between different aquifers and make it easier for groundwater to approach the roadway. Even if the roadway is far from the aquifer, it may still face the threat of water disasters due to the fault fracture zone with strong water conductivity.

[0063] It should be noted that the acquisition methods for the maximum water abundance of the aquifer and the growth rate of the average water abundance of the aquifer, the maximum permeability of the aquifer and the growth rate of the average permeability of the aquifer, the minimum thickness of the aquitard, the maximum water conductivity of the fault fracture zone and the growth rate of the average water conductivity of the fault fracture zone are as follows: Arrange the water abundances of the aquifers in each underground coal mine roadway area corresponding to each monitoring time point within the monitoring period from large to small, and extract the maximum value therefrom, thereby obtaining the maximum water abundance of the aquifers in each underground coal mine roadway area within the monitoring period.

[0064] Based on the water abundances of the aquifers in each underground coal mine roadway area corresponding to each monitoring time point within the monitoring period, obtain the growth amounts of the water abundances of the aquifers in each underground coal mine roadway area corresponding to each monitoring time point within the monitoring period, and extract the time intervals corresponding to each monitoring time point. Divide the growth amount of the water abundance of the aquifer by the time interval of the monitoring time point to obtain the growth rate of the water abundance of the aquifers in each underground coal mine roadway area corresponding to each monitoring time point within the monitoring period, and then perform a mean calculation to obtain the average growth rate of the water abundance of the aquifers in each underground coal mine roadway area within the monitoring period.

[0065] Similarly, obtain the maximum permeability of the aquifer and the growth rate of the average permeability of the aquifer, the maximum water conductivity of the fault fracture zone and the growth rate of the average water conductivity of the fault fracture zone.

[0066] Arrange the thicknesses of the water - resisting layers in each coal mine underground roadway area corresponding to each monitoring time point within the monitoring period in descending order, and extract the minimum value therefrom, thereby obtaining the minimum water - resisting layer thickness in each coal mine underground roadway area within the monitoring period.

[0067] Extract the warning values of the water - rich property, water permeability, water - resisting layer thickness, and water conductivity of the fault fracture zone stored in the database for the coal mine underground roadways, and analyze and obtain the influence indices of the water - rich property, water permeability, water - resisting layer thickness, and water conductivity of the fault fracture zone for each coal mine underground roadway accordingly.

[0068] It should be noted that the analysis processes of the influence indices of the water - rich property, water permeability, water - resisting layer thickness, and water conductivity of the fault fracture zone for each coal mine underground roadway are as follows:

[0069] Pass the maximum water - rich property and average water - rich property of each coal mine underground roadway through the influence index formula of the water - rich property of the aquifer Calculate the influence index of the water - rich property of the aquifer for each coal mine underground roadway.

[0070] Similarly, analyze and obtain the influence indices of the water permeability of the aquifer and the water conductivity of the fault fracture zone for each coal mine underground roadway.

[0071] Pass the water - resisting layer thickness of each coal mine underground roadway through the influence index formula of the water - resisting layer thickness Calculate the influence index of the water - resisting layer thickness of each coal mine underground roadway.

[0072] Convert the influence indices of the water - rich property, water permeability, and water conductivity of the fault fracture zone of each coal mine underground roadway into lengths according to a preset ratio. Respectively, take the length of the influence index of the water - rich property of the aquifer as the length, the length of the influence index of the water permeability of the aquifer as the width, and the length of the influence index of the water conductivity of the fault fracture zone as the height to construct a cuboid. Extract the numerical value of the volume of the cuboid as Result One, multiply Result One by the influence index of the water - resisting layer thickness to obtain Result Two, and take Result Two as the hydro - geological disaster risk coefficient. Thus, statistically obtain the hydro - geological disaster risk coefficients of each coal mine underground roadway area.

[0073] As a preferred feasible embodiment, the steps for determining whether there is a hydro - geological disaster risk in each coal mine underground roadway area are as follows:

[0074] Compare the hydrogeological disaster risk coefficients of each underground roadway area in the coal mines with the preset hydrogeological disaster risk coefficient threshold. If the hydrogeological disaster risk coefficient of an underground roadway area in a coal mine is greater than or equal to the preset hydrogeological disaster risk coefficient threshold, it is determined that there is a hydrogeological disaster risk in this underground roadway area of the coal mine, and the underground roadway areas in the coal mine where the hydrogeological disaster risk coefficient is greater than or equal to the preset hydrogeological disaster risk coefficient threshold are recorded as abnormal areas.

[0075] If the hydrogeological disaster risk coefficient of an underground roadway area in a coal mine is less than the preset hydrogeological disaster risk coefficient threshold, it is determined that there is no hydrogeological disaster risk in this underground roadway area of the coal mine.

[0076] As a preferred feasible embodiment, the steps of positioning the positions of each hydrogeological disaster source in the underground roadway of the coal mine are as follows:

[0077] Number each underground roadway area in the coal mine, extract the hydrogeological disaster risk coefficients and corresponding numbers of each underground roadway area in the coal mine, count the number of abnormal areas, compare the numbers of each abnormal area, calculate the difference between the maximum number and the minimum number, compare the result of the difference calculation with the number of abnormal areas, and judge whether each abnormal area is a continuous area.

[0078] It should be noted that the underground roadway areas in the coal mine are numbered sequentially starting from the entrance area of the underground roadway.

[0079] It should be noted that the method of judging whether each abnormal area is a continuous area is as follows: record the result of the difference calculation as the number difference, and then calculate the difference with the number of abnormal areas. When the difference between the number of abnormal areas and the number difference is 1, it is judged that each abnormal area is a continuous area; otherwise, it is judged that each abnormal area is not a continuous area.

[0080] If it is judged to be a continuous area, compare the hydrogeological disaster risk coefficients of each abnormal area, and select the abnormal area corresponding to the maximum hydrogeological disaster risk coefficient as the hydrogeological disaster source.

[0081] It should be noted that if it is judged to be a continuous area, it means that only one hydrogeological disaster source appears in the underground roadway of the coal mine during this monitoring period.

[0082] If it is determined that it is not a continuous area, each continuous abnormal area and each discontinuous abnormal area are obtained, and the hydrogeological disaster risk coefficients within each continuous abnormal area are compared. The abnormal area corresponding to the maximum hydrogeological disaster risk coefficient in each continuous abnormal area is selected as the hydrogeological disaster source of that continuous abnormal area. Then, the numbers of the hydrogeological disaster sources corresponding to each continuous abnormal area are counted, and the coal mine underground roadway areas corresponding to the listed numbers are the hydrogeological disaster sources of the coal mine underground roadway. At the same time, the numbers of the hydrogeological disaster sources corresponding to the discontinuous abnormal areas are listed, and the coal mine underground roadway areas corresponding to the listed numbers are the hydrogeological disaster sources of the coal mine underground roadway.

[0083] Thus, the locations of each hydrogeological disaster source in the coal mine underground roadway are determined.

[0084] It should be noted that if it is determined that it is not a continuous area, it means that there are multiple hydrogeological disaster sources in the coal mine underground roadway during this monitoring period.

[0085] Exemplarily, when the numbers of the abnormal areas are 3, 4, 5, 10, 16, 17, 18, 25, the continuous abnormal areas are 3, 4, 5 and 16, 17, 18, the discontinuous abnormal areas are 10 and 25, and the corresponding hydrogeological disaster risk coefficients are 0.62, 0.66, 0.61, 0.55, 0.63, 0.68, 0.64, 0.58, the hydrogeological disaster sources are determined to be the coal mine underground roadway areas numbered 4, 10, 17 and 25.

[0086] Step 3: Scheduling of operation drainage devices: Obtain the drainage devices closest to each hydrogeological disaster source area on the left side of the coal mine underground roadway, and mark them as the operation drainage devices on the left side and the right side of each hydrogeological disaster source area in the coal mine underground roadway, and control them to start.

[0087] It should be noted that the operation drainage devices on the left side and the right side of each hydrogeological disaster source in the coal mine underground roadway are controlled to start through the remote control center of the coal mine underground roadway drainage devices.

[0088] In a specific embodiment, the present invention intelligently identifies the locations of hydrogeological disaster sources in the coal mine underground roadway by monitoring the hydrogeological disaster-related information of the coal mine underground roadway, and starts the drainage devices near the hydrogeological disaster sources, reducing the errors caused by human intervention, accurately judging the locations where hydrogeological disasters may occur and starting the corresponding drainage devices, thereby avoiding or reducing the losses caused by hydrogeological disasters to a certain extent and ensuring the safety of coal mine underground operations.

[0089] Step 4: Regulation of the operation drainage device: Obtain the prevention and control parameters of the hydrological disaster sources detected by the left and right operation drainage devices during the prevention and control of various hydrological disaster sources in the coal mine roadway. The prevention and control parameters include water inrush flow rate, water pressure, water level, and water velocity. Analyze the reference drainage parameters of the left and right operation drainage devices for each hydrological disaster source. The drainage parameters include drainage flow rate and drainage duration, and control the left and right operation drainage devices for each hydrological disaster source.

[0090] As a preferred feasible embodiment, the steps of analyzing the reference drainage parameters of the left and right operation drainage devices for each hydrological disaster source are as follows:

[0091] Obtain the groundwater inrush flow rate, water pressure, water level, and water velocity of the hydrological disaster sources detected by the left and right operation drainage devices for each hydrological disaster source in the coal mine roadway. Calculate the ratios of the groundwater inrush flow rate, water pressure, water level, and water velocity of the hydrological disaster sources detected by the left operation drainage devices for each hydrological disaster source in the coal mine roadway to their preset inrush flow rate thresholds, water pressure thresholds, water level thresholds, and water velocity thresholds respectively, and obtain the corresponding ratio results. Sum up the ratio results corresponding to the inrush flow rate, water pressure, water level, and water velocity of the left operation drainage devices for each hydrological disaster source in the coal mine roadway according to the weights to obtain the hydrological disaster severity coefficient detected by the left operation drainage devices for each hydrological disaster source in the coal mine roadway.

[0092] It should be noted that the groundwater inrush flow rate, water pressure, water level, and water velocity of the hydrological disaster sources are collected by the flow sensors, water pressure sensors, water level sensors, and velocity sensors carried by the left and right operation drainage devices for each hydrological disaster source in the coal mine roadway.

[0093] Similarly, obtain the hydrological disaster severity coefficient detected by the right operation drainage devices for each hydrological disaster source in the coal mine roadway.

[0094] Match the hydrological disaster severity coefficients detected by the left operation drainage devices for each hydrological disaster source in the coal mine roadway and the hydrological disaster severity coefficients detected by the right operation drainage devices with the reference drainage parameters of the drainage devices corresponding to the set hydrological disaster severity coefficients to obtain the reference drainage parameters of the left operation drainage devices and the reference drainage parameters of the right operation drainage devices for each hydrological disaster source in the coal mine roadway. The drainage parameters refer to the drainage flow rate and drainage duration.

[0095] It should be noted that the remote control center of the drainage device in the coal mine underground roadway sends the reference drainage parameters of the drainage device on the left side and the reference drainage parameters of the drainage device on the right side of each hydrogeological disaster source in the coal mine underground roadway to the controller of the drainage device on the left side and the controller of the drainage device on the right side respectively, so as to regulate the drainage flow rate and drainage duration of the drainage device on the left side and the drainage device on the right side.

[0096] In a specific embodiment, the present invention monitors the groundwater inflow rate, water pressure, water level and water velocity of each hydrogeological disaster source in the coal mine underground roadway, analyzes the reference drainage parameters of the drainage devices for each hydrogeological disaster source operation, and performs corresponding control based on the reference drainage parameters, and can adaptively regulate the drainage parameters of the drainage devices in combination with the severity of the hydrogeological disaster sources, which improves the pertinence and effectiveness of the water control work in the coal mine underground roadway to a certain extent.

[0097] Step Five: Determine the drainage effect of the drainage device for operation: Analyze the drainage effect coefficient of the drainage device for operation corresponding to each hydrogeological disaster source, and determine whether the drainage effect of the drainage device for operation corresponding to each hydrogeological disaster source meets the requirements.

[0098] As a preferred feasible embodiment, the steps of analyzing the drainage effect coefficient of the drainage device for operation corresponding to each hydrogeological disaster source are as follows:

[0099] Extract the reference drainage parameters of the drainage device on the left side and the reference drainage parameters of the drainage device on the right side corresponding to each hydrogeological disaster source, and match them with the standard groundwater level drop values corresponding to the reference drainage parameters of each drainage device stored in the database respectively, to obtain the standard groundwater level drop values of the drainage device on the left side and the standard groundwater level drop values of the drainage device on the right side corresponding to each hydrogeological disaster source.

[0100] Obtain the actual groundwater level drop value of the drainage device on the left side corresponding to each hydrogeological disaster source, and calculate the ratio between it and the standard groundwater level drop value of the drainage device on the left side corresponding to each hydrogeological disaster source, to obtain the drainage effect coefficient of the drainage device on the left side for operation corresponding to each hydrogeological disaster source.

[0101] Similarly, obtain the drainage effect coefficient of the drainage device on the right side for operation corresponding to each hydrogeological disaster source.

[0102] Compare the drainage effect coefficient of the left-side operation drainage device corresponding to each hydrological disaster source with the preset drainage effect coefficient threshold. If the drainage effect coefficient of the left-side operation drainage device corresponding to a certain hydrological disaster source is greater than or equal to the preset drainage effect coefficient threshold, it is determined that the drainage effect of the left-side operation drainage device corresponding to this hydrological disaster source meets the requirements. If the drainage effect coefficient of the left-side operation drainage device corresponding to a certain hydrological disaster source is less than the preset drainage effect coefficient threshold, it is determined that the drainage effect of the left-side operation drainage device corresponding to this hydrological disaster source does not meet the requirements.

[0103] Similarly, determine whether the drainage effect of the right-side operation corresponding to each hydrological disaster source meets the requirements.

[0104] Step Six: Auxiliary operation drainage device scheduling: When it is determined that the drainage effect of the left-side operation drainage device or the right-side operation drainage device corresponding to a certain hydrological disaster source does not meet the requirements, start the left-side auxiliary operation drainage device or the right-side auxiliary operation drainage device of each hydrological disaster source and control its startup.

[0105] It should be noted that the left-side auxiliary operation drainage device refers to the left-side drainage device that is close to this hydrological disaster source and is not working, and the right-side auxiliary operation drainage device refers to the right-side drainage device that is close to this hydrological disaster source and is not working.

[0106] It should be noted that the left-side auxiliary operation drainage device and the right-side auxiliary operation drainage device of each hydrological disaster source in the coal mine underground roadway are controlled to start through the remote control center of the coal mine underground roadway drainage device.

[0107] Step Seven: Auxiliary operation drainage device regulation: Analyze the reference drainage parameters of the left-side auxiliary operation drainage device and the right-side auxiliary operation drainage device of each hydrological disaster source, and control the left-side auxiliary operation drainage device and the right-side auxiliary operation drainage device of each hydrological disaster source.

[0108] As a preferred feasible embodiment, the steps of analyzing the reference drainage parameters of the left-side auxiliary operation drainage device and the right-side auxiliary operation drainage device of each hydrological disaster source are as follows:

[0109] Perform a difference calculation on the drainage effect coefficient of the left-side operation drainage device of each hydrological disaster source and the preset drainage effect coefficient threshold to obtain the drainage effect coefficient difference of the left-side operation drainage device of each hydrological disaster source, and match it with the reference drainage parameters of the left-side auxiliary operation drainage device corresponding to the preset drainage effect coefficient difference of each left-side operation drainage device to obtain the reference drainage parameters of the left-side auxiliary operation drainage device of each hydrological disaster source.

[0110] Similarly, according to the analysis method of the reference drainage parameters of the left auxiliary operation drainage device for each hydrological disaster source, the reference drainage parameters of the right auxiliary operation drainage device for each hydrological disaster source are obtained.

[0111] It should be noted that the reference drainage parameters of the left auxiliary operation drainage device and the reference drainage parameters of the right auxiliary operation drainage device for each hydrological disaster source in the coal mine underground roadway are respectively sent to the controller of the left auxiliary operation drainage device and the controller of the right auxiliary operation drainage device through the remote control center of the coal mine underground roadway drainage device, so as to regulate the drainage flow rate and drainage duration of the left auxiliary operation drainage device and the right auxiliary operation drainage device.

[0112] In a specific embodiment, the present invention monitors the drainage effect of the operation drainage devices on both sides of the hydrological disaster source to judge whether it meets the requirements. If it does not meet the requirements, the auxiliary operation drainage devices on both sides of the hydrological disaster source are started and regulated, and their reference drainage parameters are analyzed and regulated according to the actual situation, further enhancing the drainage capacity and ensuring effective drainage operations under various complex hydrological disaster conditions and guaranteeing the safety in the coal mine underground.
