[0025] Method Embodiment

[0026] According to an embodiment of the present invention, a method for monitoring illegal operations in a hidden working face of a coal mine is provided. Figure 1 Flow chart of the method for illegal monitoring of hidden working face in coal mine according to an embodiment of the present invention. Figure 1 As shown, specifically including:

[0027] S1. Obtaining real-time dynamic subsidence data of the surface during coal mining based on Beidou satellite and radar satellite remote sensing;

[0028] S2. Based on mining subsidence theory, the mining subsidence parameters are continuously revised through monitoring data;

[0029] S3. Compare the dynamic sinking data monitored in real time with the sinking state calculated theoretically. If there is a difference, there is a hidden working face;

[0030] S4. Based on the coal seam conditions and mining progress of the working face, obtain illegal production and illegal activities of the hidden working face of the coal mine;

[0031] S5. Based on the mining scope, production drawings, production and sales records and reserve record data, early warnings will be issued to determine whether the coal mine has falsified drawings, false reporting of actual mining, illegal production and mining in hidden working faces, and illegal and irregular production beyond capacity.

[0032] Continuously correcting coal mining subsidence parameters through monitoring data specifically includes: continuously correcting coal mining subsidence parameters through monitoring data, and the monitoring data includes: Beidou high-precision satellite positioning data, satellite remote sensing InSAR data, ground observation station data and coal mining situation data.

[0033] The monitored dynamic subsidence data is compared with the subsidence status calculated by probability integral. If there is a difference, a hidden working face exists.

[0034] The specific implementation methods are as follows:

[0035] The present invention mainly utilizes Beidou high-precision technology and radar satellite remote sensing technology to obtain real-time dynamic subsidence data of the surface of coal mining in a "point" and "surface" combination. According to the mining subsidence theory, the mining subsidence parameters of coal mining are continuously corrected through a large amount of monitoring data. At the same time, the "sinking state monitored in real time" is compared with the "theoretical calculated sinking state". Combined with the coal seam conditions of the working face and the mining progress, illegal production and illegal activities of the hidden working face of the coal mine can be quickly and accurately discovered. Combined with the mining scope, production drawings, production and sales records, reserves records and other information, the system can issue early warnings on whether there are illegal and irregular activities such as falsification of drawings, false reporting of actual mining, illegal production and mining of hidden working faces of coal mines, and overcapacity production in coal mines.

[0036] 1. Deploy Beidou high-precision positioning instruments at the center line of the coal mine's strike (inclination) working face, the maximum subsidence point, the turning point, and outside the mine boundary to monitor the ground subsidence in real time;

[0037] 2. Use InSAR, D-InSAR, LiDAR and other technologies to accurately and widely obtain surface deformation information;

[0038] 3. Use the probability integral method to carry out surface subsidence, inclination, curvature, horizontal movement and horizontal deformation of multi-working face mining of arbitrary shapes according to the surface movement parameters;

[0039] Compare the calculated results of step 3 with the measured results of steps 1 and 2. If there is a difference, there is a hidden working surface.

[0040] 1. Change the previous regular downhole measurement into dynamic automatic monitoring;

[0041] Illegal production activities in hidden working faces of coal mines are highly concealed. Problems such as long underground working time, low judgment and analysis efficiency, and difficulty in large-scale and refined monitoring of traditional underground measurement and verification methods are becoming increasingly prominent and cannot meet regulatory needs. The positioning accuracy of the Beidou system is at the millimeter level, and it has the ability to monitor in real time. Radar satellite technology can monitor large-scale surface deformations around the clock and all-weather, and can quickly obtain surface deformation information of the entire monitoring area with deformation monitoring accuracy at the millimeter level, greatly improving monitoring efficiency. The application of the two new monitoring technologies will transform the previous regular underground measurements into dynamic and automated monitoring, with richer monitoring data, capable of obtaining surface deformation information with high temporal resolution and high spatial resolution, more accurately providing comprehensive deformation information for the monitoring area, analyzing the law of surface subsidence, and more conducive to the monitoring of illegal production activities in hidden working faces of coal mines, making automated monitoring more scientific, efficient and accurate.

[0042] 2. Strengthened the daily supervision and management of mineral resource exploitation;

[0043] Through Beidou high-precision positioning and radar satellite remote sensing, a large amount of data is obtained. Under the guidance of coal mining subsidence theory and the calculation of the software system, the mine status is monitored in real time and sent to natural resources authorities, emergency management departments, production safety supervision agencies, etc. at all levels. Law enforcement departments promptly share illegal production monitoring information on hidden working faces in coal mines, conduct regular joint inspections, supervision and spot checks on abnormal mines, and regularly report on the investigation and handling of illegal production and illegal mining behaviors in hidden working faces of coal mines. This is of great significance to consolidate the results of the work of rectifying and standardizing the order of mineral resource development, maintain the order of mineral resource exploration and mining, curb illegal behaviors, and effectively protect and rationally utilize mineral resources.

[0044] 3. Prevent safety accidents caused by "false and fake" drawings;

[0045] Coal mine drawings are important technical data required by law for coal mine production and construction. Enterprises provide false information to deal with inspections, and falsify drawings to conceal illegal construction at mining working faces. Falsification of drawings creates obstacles for safety supervision departments to go down to the mine for inspection and buries hidden dangers for disaster rescue. In particular, when exchanging drawings with nearby mines, providing wrong information can easily cause accidents such as mistaken water seepage areas and mistaken gas tunnels. In addition, if the drawings are inaccurate, once an accident occurs, it will be extremely difficult to determine the cause of the accident, search and rescue workers in the disaster area, and especially formulate a search and rescue plan, which will delay the best time for emergency rescue. After the introduction of this system, the drawings uploaded by each coal mine can be checked and abnormal drawings can be analyzed.

[0046] 4. Provide data support for the safe development and utilization of coal mining subsidence areas in the future;

[0047] The scope of coal mining subsidence in mining cities is large, which conflicts with the needs of urban development and expansion. There are many coal mines in our city, and the area of ​​newly added goaf areas will reach 100 million in the future. By then, most coal mining subsidence areas will be in the residual deformation stage, and the residual voids and coal pillars in the old goaf areas may become unstable under the influence of groundwater and loads. The buildings (structures) on the surface will be affected, posing a threat to the safety of life and property of residents. Due to the uneven subsidence of the surface, the roads, bridges, water supply and drainage pipelines, power supply, communication lines and other facilities within the subsidence range will produce deformations such as tension, compression, and bending. The municipal facilities will be damaged by the residual deformation, which will have a great impact on the daily life of residents. Therefore, long-term monitoring of the surface subsidence in our city is of great significance to the future safe and sustainable development of the city.

[0048] 5. It can timely and accurately grasp the dynamic changes of geological disaster hazards;

[0049] The geological disasters in our city are widely distributed, of many types, and of great harm. The main geological disasters include collapse, landslide, mudslide, ground subsidence, soil erosion, etc. The occurrence of geological disasters will lead to a series of ecological and environmental problems, and will also cause social and economic problems such as damage to the national economy and loss of life and property of the people. Displacement deformation is the most intuitive precursor information of the occurrence of geological disaster bodies, and is the main basis for early warning and forecasting of geological disasters. Therefore, through this system, we can provide strong automatic monitoring technical support for the city's geological disaster risk points, dangerous steep slopes of highways, dangerous steep slopes of railways, and dam deformation.

[0050] The present invention currently mainly uses Beidou high-precision technology, radar satellite remote sensing technology, and coal mining subsidence theory. However, other alternatives include but are not limited to the use of other satellite remote sensing, drone remote sensing, microseismic technology, optical fiber and other mining sensors.

[0051] The present invention can achieve the following contents:

[0052] 1: Comprehensively adopt mining subsidence theory, Beidou high-precision positioning technology, radar satellite remote sensing technology, etc. to monitor illegal production in hidden working faces of coal mines;

[0053] 2: Through mining subsidence theory, Beidou high-precision positioning technology, and radar satellite remote sensing technology, continuous real-time and high-precision monitoring of large areas and multiple coal mines is carried out;

[0054] 3: Based on the surface subsidence data, geological conditions of the survey area and other ground data, the coal mine production situation is inferred through the mining subsidence theory, and then it is determined whether there are any illegal production activities in the hidden working face of the coal mine.
