For example, the terminal can be a smart phone, a computer, a tablet computer, a smart television, a smart watch, a portable computer terminal, and a fixed terminal such as a desktop computer. For convenience of description, the terminal is taken as an example in the present application.
[0080] Referring to Figure 1 The present application first provides an embodiment of a coal mine water flowing fractured zone observation method, which comprises the following steps.
[0081] S101, constructing an initialized transparent geological model;
[0082] In the present embodiment, the geological model is a digital model constructed on the basis of multi-source geological data, which is used to depict the characteristics of stratum structure, lithology distribution, and geological structure, so as to visualize the internal information of the geological body.
[0083] In the construction of the transparent geological model, first, geological data acquisition is carried out, and multi-source geological data such as stratum structure, lithology distribution, and hydrogeological conditions are collected. Then, the OCR technology and image processing technology are used to digitize the geological data and obtain the digital format of the geological data. Next, the GIS technology is used to align the spatial coordinates of the digital format of the geological data, combine the geological data with the actual situation, and ensure the accuracy and consistency of the geological data. Further, the three-dimensional modeling software is used, and the stratum framework model is constructed based on the surface modeling method, the top and bottom surface shapes of each rock layer and the contact relationship are depicted, and the key geological structures such as faults and folds are targeted. Finally, the physical parameters are given to the stratum framework model according to the rock physical property data, and the initialized transparent geological model is obtained.
[0084] S102, acquire historical fracture zone electrochemical method data;
[0085] In this embodiment, the fracture zone electrochemical method data refers to the data related to the rock fracture zone obtained by the borehole electrical prospecting technology in the geological environment monitoring of coal mines and the like, mainly including resistivity, potential, etc., which can reflect the electrical properties of the rock mass.
[0086] In acquiring the historical fracture zone electrochemical method data, first, according to the time span, the specific position of the borehole, and the specific type of the electrical measurement parameters such as resistivity and potential, etc., key elements are screened, and the electrical method data closely related to the roof water flowing fractured zone is extracted from a large amount of historical coal mine data. Then, the screened electrical method data is subjected to quality inspection, identification of abnormal data, and elimination of data. Finally, a batch of historical fracture zone electrochemical method data is obtained, which is used for subsequent training of the initialized transparent geological model.
[0087] S103, processing the historical fracture zone electrochemical method data by using the initialized transparent geological model to construct a virtual mirror of the roof water flowing fractured zone;
[0088] In this embodiment, the virtual mirror of the roof water flowing fractured zone is a digital presentation of the geological conditions of the roof water flowing fractured zone, which can reflect the dynamic changes of the roof water flowing fractured zone in real time, provide key basis for the safety production and rational exploitation of coal mines, and effectively prevent water inrush accidents.
[0089] In constructing the virtual mirror of the roof water flowing fractured zone, firstly, the historical fractured zone electrical data is matched with the initialized transparent geological model, and the resistivity and potential parameters in the electrical data are corresponded to the corresponding stratum position in the initialized transparent geological model according to the drilling position information. Then, based on the relationship between the petrophysical property and the electrical parameter, the historical fractured zone electrical data is converted into the parameters reflecting the characteristics of the roof water flowing fractured zone, including the width, length, trend, density and water content of the fracture. Finally, the parameters of the characteristics of the roof water flowing fractured zone are integrated into the initialized transparent geological model, and the three-dimensional visualization technology is used to visually present the fractured zone in the model, so that the virtual mirror of the roof water flowing fractured zone is constructed.
[0090] Specifically, one possible implementation of this step includes:
[0091] Step 1, spatially register the historical fractured zone electrical data and the initialized transparent geological model to obtain the three-dimensional spatial position of the historical fractured zone electrical data;
[0092] In this embodiment, when obtaining the three-dimensional spatial position of the historical fractured zone electrical data, the historical fractured zone electrical data needs to be preprocessed, including standardized conversion of data format to ensure compatibility with the data format of the initialized transparent geological model. Then, the registration algorithm based on feature points or feature surfaces is used to extract representative geological features such as obvious stratum interfaces and fault lines in the historical fractured zone electrical data and the initialized transparent geological model. Then, by calculating the geometric transformation relationship between these geological features, including translation, rotation and scaling parameters, the historical fractured zone electrical data is accurately mapped into the three-dimensional spatial coordinate system of the initialized transparent geological model, so that the three-dimensional spatial position of the historical fractured zone electrical data is obtained.
[0093] Step 2, process the three-dimensional spatial position and the initialized transparent geological model to obtain the electrical data feature representation;
[0094] In this embodiment, when obtaining the electrical data feature representation, a data interpolation algorithm needs to be used to refine and expand the electrical data in space according to the geological model information around the three-dimensional spatial position. Then, through statistical analysis, the average value, variance, gradient and other statistical quantities of the fused data in different regions are calculated. At the same time, the electrical data is associated with the rock type and stratum structure information by combining the electrical properties of the geological body, so that the electrical data feature representation which can intuitively reflect the geological characteristics and physical properties of the roof water flowing fractured zone is formed.
[0095] Step 3, construct the virtual mirror of the roof water flowing fractured zone according to the three-dimensional modeling technology and the electrical data feature.
[0096] In this embodiment, when constructing the virtual mirror of the roof water-conducting fractured zone, the approximate outline of the roof water-conducting fractured zone is initially sketched according to the characteristics of the low resistivity anomaly area presented by the electrical method data, and the distribution range and trend of the roof water-conducting fractured zone in the three-dimensional space are determined. Then, the electrical method data characteristics are converted into specific three-dimensional geometric structures by using triangular meshing and other methods, and the basic framework of the virtual mirror of the roof water-conducting fractured zone is accurately constructed. Further, according to the parameters obtained from the principles of geomechanics and rock physics experiments, the constructed basic framework is endowed with real permeability, porosity and other attributes, so as to be consistent with the actual geological conditions. Moreover, referring to the geological data and rock physics attribute data, the corresponding physical property parameters, including permeability and porosity, are assigned to the fractured zone in the model, thereby enhancing the authenticity of the model. Finally, through simulation algorithms and in combination with the law of geological evolution, the constructed virtual mirror is dynamically simulated and repeatedly checked and optimized, so as to obtain the virtual mirror of the roof water-conducting fractured zone.
[0097] In this implementation, the three-dimensional spatial position of the historical fractured zone electrical method data is obtained by spatially registering the historical fractured zone electrical method data with the initialized transparent geological model, so as to effectively avoid analysis errors caused by position deviation and improve the accuracy of the position judgment of the roof fractured zone. Then, the three-dimensional spatial position is fused and extracted with the initialized transparent geological model to obtain the electrical method data characteristics, which can more clearly show the correlation between the electrical characteristics of the geological body and the geological structure, and help to deeply understand the formation mechanism of the roof water-conducting fractured zone. Further, the virtual mirror of the roof water-conducting fractured zone is constructed according to the three-dimensional modeling technology and the electrical method data characteristics, which can visually display the morphology, trend and physical properties of the roof water-conducting fractured zone, thereby providing a guarantee for reducing the safety risk in the subsequent mining process and improving the efficiency and safety of coal resource mining.
[0098] S104, processing the virtual mirror of the roof water-conducting fractured zone using a numerical simulation algorithm to obtain simulation monitoring data;
[0099] In this embodiment, the numerical simulation algorithm is a calculation method for simulating physical phenomena or processes by using mathematical models and computer technology. In the study of the coal mine roof water-conducting fractured zone, it is a means for obtaining system evolution information by establishing mathematical and physical equations and solving these equations by numerical calculation. The principle is to discretize the continuous physical space and time, and convert the complex actual problem into a discrete numerical problem that can be processed by a computer.
[0100] When acquiring simulated monitoring data, it is necessary to select a suitable numerical simulation algorithm. Taking the finite difference method as an example, the virtual image of the roof water-conducting fracture zone is imported into a suitable numerical simulation software environment. Next, based on the actual geological conditions of the coal mine site, such as the lithological distribution of strata, structural characteristics, and the layout of mining operations, the boundary conditions of the numerical simulation software environment are set. Then, the time step is determined according to the stability requirements of the finite difference method, and the simulation duration is set in conjunction with the research objectives. Then, the virtual image of the roof water-conducting fracture zone is meshed, and the mesh is refined in and around the fracture zone to improve accuracy. Finally, the simulation calculation is started, and the finite difference method is used to approximate the solution of the seepage and mechanical equations. Simulated monitoring data such as stress, deformation, and pore water pressure of the roof water-conducting fracture zone are obtained through iterative calculations and output in a visualized form.
[0101] S105. Obtain monitoring difference data based on the electrical resistivity data characteristics corresponding to the simulated monitoring data and the early warning threshold;
[0102] In this embodiment, the early warning threshold is determined based on safety standards for coal mine roofs and past engineering experience, combined with statistical analysis of simulated monitoring data and electrical resistivity tomography (ERT) data. ERT data characteristics refer to the specific properties of the ERT data related to the early warning situation during the monitoring of water-conducting fracture zones in coal mine roofs.
[0103] When acquiring monitoring discrepancy data, it is first necessary to clarify the various parameters in the simulated monitoring data, such as the stress, deformation, and pore water pressure in the roof's water-conducting fracture zone, as well as the electrical resistivity data characteristics corresponding to the warning threshold, including the range and trend of key electrical resistivity parameters such as resistivity and potential. Next, the simulated monitoring data is analyzed and compared with the warning threshold. Furthermore, the difference between the simulated monitoring data and the warning threshold is calculated to obtain monitoring discrepancy data that reflects the degree of deviation between the actual situation and the potential risk state.
[0104] The difference data is calculated using the first formula:
[0105] ;
[0106] in, This represents simulated monitoring data. This indicates the electrical resistivity data characteristics corresponding to the warning threshold. This indicates the monitoring of discrepancies. Indicates the range of warning thresholds.
[0107] S106. Optimize the initial transparent geological model based on the monitored difference data to obtain the target geological model;
[0108] In the embodiment, when the target geological model is acquired, the monitoring difference data is first processed by the second formula to obtain a parameter adjustment value:
[0109] ;
[0110] wherein, represents the parameter adjustment value, represents the geological model parameter value before updating, represents the monitoring difference data, represents the parameter update proportion coefficient;
[0111] Then, the parameter adjustment value is processed by the third formula to obtain an updated geological model parameter value:
[0112] ;
[0113] wherein, represents the updated geological model parameter value, represents the parameter adjustment value, represents the geological model parameter value before updating;
[0114] Finally, the initialized transparent geological model is optimized according to the updated geological model parameter value to obtain the target geological model.
[0115] According to the updated geological model parameter value, the initialized transparent geological model is optimized to obtain the target geological model.
[0116] S107, collecting fracture zone electrical method data by borehole electrical method technology;
[0117] In the embodiment, the borehole electrical method technology is a technology of placing electrodes in a borehole, supplying stable current to the underground, and forming an electric field around the borehole, which is used to measure electric parameters such as potential and resistivity at different positions in the borehole, and infer the distribution of geological bodies according to the variation characteristics of these parameters.
[0118] In the process of collecting the fractured zone electrical method data, firstly, according to the coal mine geological data and the mining plan, the borehole layout is reasonably determined at the key position of the roof, and the parameters such as the number, spacing, depth and angle of the borehole are determined, so as to ensure that the roof water flowing fractured zone can be effectively detected. Then, the professional drilling equipment is used for construction, the verticality and aperture of the borehole are strictly controlled, the hole collapse and hole wall damage are prevented, and the hole wall protection work is well done, so as to ensure the smooth follow-up detection. Further, after the completion of the borehole, the pre-calibrated electrical method probe is slowly put into the borehole through the cable, the probe is ensured to reach the predetermined detection depth and tightly contact with the hole wall, so as to obtain the accurate electrical method signal. Finally, the high-precision electrical method measuring instrument is used, and the electrical method data of different positions in the borehole is collected according to the set measurement parameters such as different frequencies of current and voltage, so that the fractured zone electrical method data can be obtained.
[0119] S108, input the fractured zone electrical method data into the target geological model to obtain monitoring data;
[0120] In the embodiment, when the monitoring data is obtained, the collected fractured zone electrical method data needs to be sliced and data compression processed, so that the collected fractured zone electrical method data is matched with the data interface of the target geological model. Then, the processed fractured zone electrical method data is imported into the target geological model. Further, the target geological model combines the input fractured zone electrical method data according to the built-in geological structure, rock physical property and other parameter information, and uses professional numerical calculation method and algorithm such as inversion algorithm based on electrical principle and geological statistics to fuse and analyze the data, so that the development of the roof water flowing fractured zone, the fractured water conductivity and other monitoring data can be obtained.
[0121] S109, judge whether the monitoring data exceeds the early warning threshold value;
[0122] In the embodiment, when it is judged whether the monitoring data exceeds the early warning threshold value, the current obtained monitoring data is compared with the corresponding early warning threshold value one by one. When the monitoring data is greater than the set early warning threshold value, it indicates that the state of the roof water flowing fractured zone may be abnormal, and there is a situation that the water inrush or roof collapse and other safety risks are intensified, and the system executes step S110. When the monitoring data does not exceed the early warning threshold value, it indicates that the roof water flowing fractured zone is currently in a relatively stable and safe state, and the system will continue to run normally, and continue to collect and update the fractured zone electrical method data according to the set time interval and program requirements.
[0123] S110, trigger the early warning mechanism.
[0124] In this embodiment, when the monitoring data exceeds the early warning threshold, the early warning mechanism is triggered immediately. Then, the early warning mechanism determines the level of this early warning according to the correspondence between the preset alarm level and the extent of data exceeding the limit, such as slight, moderate, severe, etc. Further, through various communication channels, including but not limited to mass SMS, sound and light alarm devices, and voice notification systems, detailed early warning information is sent to relevant management personnel, front-line workers, and safety supervision departments of the coal mine, informing them of the abnormal situation of the roof water-conducting fractured zone and the risk of water inrush or roof collapse. At the same time, emergency plans are started, such as suspending mining operations, organizing personnel to evacuate dangerous areas, strengthening roof support and drainage preparation, etc., to minimize the possibility and harm of safety accidents.
[0125] In this embodiment, the present application provides an intuitive framework for the integration of geological information by constructing an initialized transparent geological model. Then, the historical fractured zone electro-facture data is processed using the initialized transparent geological model to construct a virtual mirror of the roof water-conducting fractured zone, making the geological structure more clear and present, providing an intuitive and visual means for coal mine safety monitoring, which helps to timely discover and handle safety hazards. Then, the virtual mirror of the roof water-conducting fractured zone is processed using a numerical simulation algorithm to obtain simulated monitoring data, which can discover the trend of changes in the roof water-conducting fractured zone and effectively reflect the defects of the actual situation of the coal mine roof water-conducting fractured zone. Further, the simulated monitoring data is compared with the early warning threshold, and the transparent geological model is optimized based on the monitoring difference data obtained by the comparison, so that the transparent geological model can continuously approach the real geological situation, enhancing the reliability and adaptability of the geological model. Furthermore, real-time fractured zone electro-facture data is collected by borehole electro-facture technology and input into the target geological model to obtain monitoring data, realizing real-time dynamic monitoring of the coal mine roof water-conducting fractured zone, which can timely grasp the changes in the roof state. Compared with the traditional manual data collection method, the monitoring efficiency is greatly improved. Finally, by judging whether the monitoring data exceeds the early warning threshold, potential geological disaster risks can be discovered in time, and once the early warning mechanism is triggered, response measures can be taken quickly to reduce the risk of personnel casualties and property losses, realizing intelligent coal mine safety production.

[0127] S201, obtaining geological material information;
[0128] In this embodiment, the geological material information mainly consists of geological information such as stratigraphic structure, lithology distribution, and hydrogeological conditions.
[0129] In obtaining geological material information, first, for stratum structure information, detailed geological profile and plan are drawn through geological surveying and mapping means, and the interfaces, thicknesses and occurrences of different strata are marked. Then, the accurate stratification and specific characteristics of each layer are further determined by using drilling core data. Next, for lithology distribution, the outcrop of rock is observed in the field, and the type and distribution range of rock are accurately determined by preliminary identification of the appearance characteristics such as color, texture and hardness of rock, thin section identification under a microscope and various rock physical and chemical property tests. Further, for hydrogeological conditions, hydrogeological investigation is carried out, and parameters such as groundwater level, flow direction and flow rate are measured, and the distribution and properties of aquifer and aquiclude are analyzed to determine the recharge, runoff and discharge paths of groundwater. Finally, the stratum structure, lithology distribution and hydrogeological condition information are collected to obtain the geological material information of the coal mine area.

[0136] In constructing the initialized transparent geological model, first, according to the stratum distribution, lithological characteristics and structure information in the target geological data, a basic geometry shape is created in the three-dimensional modeling software, such as a polygonal sheet representing different strata, and its spatial position is accurately positioned by the coordinate value in the data to construct a preliminary geological structure framework. Then, according to the lithological properties and the like, specific materials and colors are given to each part, and the model is made transparent by using the transparency setting to facilitate observation of the internal structure. Further, interpolation calculation, gap filling and model detail improvement and the like are performed on the target geological data, and an initialized transparent geological model that can accurately reflect the spatial form and attribute characteristics of the geological body is constructed.

[0139] S301, according to the coal mine roof fracture zone detection requirement, set the drilling position;
[0140] In this embodiment, when setting the drilling position, detailed geological data of the coal mine need to be collected, including stratum structure, lithology distribution, geological structure (such as faults, folds, etc.) and previous mining conditions and the like. Then, the geological data is analyzed and processed to determine the area where the roof fracture zone is likely to develop and the potential trend. Then, according to the area where the roof fracture zone is likely to develop and the potential trend, combined with the mining plan of the coal mine and the actual situation on site, the layout and key parameters of the drilling, such as the spacing, angle, depth and the like of the drilling, are determined to ensure that the target area can be effectively detected. Further, the geophysical technology personnel use high-precision measuring instruments to set the hole and drill according to the target area, fix the hole diameter to 75 mm, and drill according to the established parameters. Further, when drilling about 10 m, a 7 m casing is installed and the mouth is locked, the hole wall stability is closed and reinforced by grouting to prevent collapse. Finally, after the grouting is fully solidified, the locked mouth is reopened to sweep the hole and continue drilling. If broken zone or water anomaly is encountered during the process, grouting treatment is carried out in time, and after the normality is restored, the drilling is continued. At the same time, the drilling is strictly operated according to the parameters throughout the whole process, and the inclination is measured at regular intervals to correct the drilling direction in real time. After the drilling is completed, the inclination is measured again to confirm the accuracy of the final hole position, and the accurate two-point drilling position can be obtained.
[0141] S302, setting an electrical method probe device in the drilling position by using an electrical method instrument;
[0142] In this embodiment, the electrical method instrument is a device used for electrical method detection in geophysical exploration. It obtains geological information by sending and receiving electrical signals to underground media. For example, it can emit current and measure potential difference or resistivity, use the difference in electrical conductivity of different rocks and ores to detect geological body distribution, structure and underground water conditions, and is an important tool in the fields of geological exploration and the like. The electrical method probe device can emit electrical signals to geological bodies, which change due to the difference in electrical conductivity of geological bodies during propagation, and the probe can receive these changed signals. On this basis, the electrical method instrument can obtain electrical method data reflecting geological structure, rock characteristics and fracture distribution, etc., to assist geological exploration and analysis.
[0143] When setting the electrical method probe device, the electrical method probe and transmission cable need to be prepared after the drilling position is determined and the inclination result meets the requirements. The connection parts of the electrical method probe and the cable are carefully treated, professional waterproof tape and insulating materials are used to ensure the stability and sealing of the connection to prevent water ingress and leakage from affecting signal transmission. Then, the connected electrical method probe is fixed on a special lowering device, the lowering operation is started, and the probe is lowered along the drilling hole at a slow and stable speed. The lowering depth is closely monitored during the process, and the probe is closely attached to the hole wall by slightly adjusting the lowering device, so that the electrical method probe device in the drilling position can be set.
[0144] S303, grouting and hole sealing are performed on the drilling position to obtain a drilling measurement environment;
[0145] In this embodiment, when obtaining the drilling measurement environment, it is necessary to determine that the electrical prospecting probe has been set in the drilling as required, and then the cement-based or chemical grouting material is adjusted according to the characteristics of the drilling to ensure that it can effectively fill the pores and has stability and insulation after solidification. Then, after flushing the drilling, the grouting pump is started to slowly inject material from the bottom, and the grouting pipe is lifted synchronously to make the material uniformly distributed in the hole, and the grouting pressure and speed are accurately controlled to prevent the hole wall from being damaged by excessive pressure or uneven filling caused by excessive speed. Further, the grouting is continuously performed until the grouting material overflows at the hole, and then the grouting material is allowed to solidify, thereby forming a closed drilling measurement environment isolated from external interference.
[0146] S304, starting the electrical prospecting probe device according to the drilling measurement environment to obtain the fracture zone electrical prospecting data.
[0147] In this embodiment, after the drilling is sealed by grouting to form a stable drilling measurement environment, the electrical prospecting instrument is connected with the installed electrical prospecting probe device. According to the detection target and geological conditions, appropriate parameters are set on the electrical prospecting instrument, including current intensity, frequency range, etc. Then, after starting the instrument, the electrical prospecting probe emits electrical signals to the surrounding geological body, and these signals change when passing through the roof fracture zone due to the difference in rock conductivity. Then, the electrical prospecting probe device receives the reflected or refracted electrical signals and collects, amplifies, filters and converts the signals to convert them into fracture zone electrical prospecting data such as apparent resistivity that can reflect the characteristics of the fracture zone.
[0148] In this embodiment, by combining the drilling position with the electrical prospecting technology, the distribution, trend and development state of the roof fracture zone and other key information can be accurately determined, so that the mining scheme can be optimized, and accidents such as roof collapse caused by blind mining can be avoided, thereby effectively ensuring the safety of personnel and stable operation of equipment. Then, by starting the electrical prospecting probe device according to the drilling measurement environment, the fracture zone electrical prospecting data is obtained, which provides a data basis for predicting possible geological disaster hidden dangers such as water inrush and gas leakage.
[0149] Please refer to Figure 4 , Figure 4 Another embodiment of a coal mine water-guiding fracture zone observation method provided in the present application includes:
[0150] S401, allocating a special network channel for the fracture zone electrical prospecting data by using F5G slicing technology;
[0151] In this embodiment, the F5G slice technology can open up special network resources for the crack electrokinetic method data, and create an independent slice through logical isolation. The bandwidth can be finely configured according to the data requirements, the transmission delay is reduced, and the data problems caused by network congestion are avoided. The stable and rapid transmission of data is ensured, and the efficient processing and utilization of the coal mine roof crack detection data are ensured.
[0152] When allocating a special network channel, the network architecture inside the coal mine needs to be comprehensively evaluated, including existing network bandwidth, transmission delay, reliability and other parameters, to determine the basic network resource channel that can be allocated to the crack electrokinetic method data transmission. Then, the fifth generation fixed network device is deployed, and a separate and logically isolated network slice is created according to the transmission requirements of the crack electrokinetic method data through network slicing technology. Further, the slice is finely configured to set up a dedicated bandwidth resource channel to ensure stable and rapid data transmission during data transmission peak periods, that is, the allocation of a special network channel is completed.
[0153] S402, processing the crack electrokinetic method data to obtain crack electrokinetic method compressed data;
[0154] In this embodiment, when obtaining the crack electrokinetic method compressed data, a data compression algorithm is used to compress the crack electrokinetic method data, wherein the data compression algorithm is used to remove redundant information in the crack electrokinetic method data, reduce the storage space of the data, and reduce the transmission bandwidth requirement without losing key geological feature information, so that the data transmission and storage are more efficient.
[0155] S403, data verification optimization is performed on the crack electrokinetic method compressed data to obtain target crack electrokinetic method data;
[0156] In this embodiment, for the crack electrokinetic method compressed data, a specific data verification algorithm is used to calculate the verification value at each key node of data transmission and compare it with the pre-stored standard verification value. If the verification does not match, it means that the data may have errors or be lost. At this time, the error correction program is started, and for slight errors, redundant data or interpolation algorithm is used for repair; for serious problems, the data source is traced back to reacquire. Through continuous verification and error correction, the data integrity and accuracy are ensured, and finally reliable target crack electrokinetic method data is obtained.
[0157] S404, inputting the target crack electrokinetic method data to the target geological model through the special network channel to obtain monitoring data.
[0158] In this embodiment, when acquiring monitoring data, a special network channel is needed to be built to ensure that the target fracture zone electrical method data is input from the electrical method probe device in the borehole measurement environment to the target geological model for calculation. Then, the target geological model combines the input target fracture zone electrical method data with the built-in geological structure, rock physical properties and other parameter information, and uses numerical calculation methods such as inversion algorithms based on electrical principles and geological statistics to fuse and analyze the target fracture zone electrical method data, so as to obtain the development of the roof water-conducting fracture zone and the fracture water conductivity monitoring data.
[0159] In this embodiment, the F5G slicing technology is used to allocate a special network channel to ensure the high-speed and stable transmission of the fracture zone electrical method data, avoiding data delay or loss caused by network congestion. Then, the fracture zone electrical method data is compressed to greatly reduce the storage space and transmission bandwidth requirements, improving the data storage and transmission efficiency. Further, the fracture zone electrical method compressed data is checked and optimized to ensure the accuracy and integrity of the data, providing reliable support for coal mine roof condition analysis. Finally, the target fracture zone electrical method data is input into the target geological model through the special network channel to obtain monitoring data, so that the system can master the dynamic changes of the roof fracture zone in real time, which helps to take preventive measures in advance, improves the safety and production efficiency of coal mining, and also ensures the safety of personnel life and the economic benefits of enterprises.
