Description

Technical Field

[0001] The present invention relates to the technical field of geological disaster prevention and control technology, and more specifically to a three-dimensional dynamic monitoring method and system for mining subsidence and a readable storage medium. Background Art

[0002] Currently, after minerals are mined and transported, the original mechanical equilibrium within the rock mass surrounding the mining area is disrupted, causing rock strata to shift, deform, and fail. Once the mining area reaches a certain size, this shift and failure will spread to the surface, causing deformation or damage to buildings, railways, rivers, and shafts within the mining area. Therefore, subsidence monitoring in mining areas is a crucial research topic in the field of mining engineering.

[0003] However, since the factors affecting ground subsidence in mining areas are complex and changeable, and have a strong randomness, although traditional leveling and GPS monitoring methods have high monitoring accuracy, their time-consuming, labor-intensive and low processing efficiency have limited their development.

[0004] Therefore, how to provide a three-dimensional dynamic monitoring method for mining subsidence that can solve the above problems is an issue that those skilled in the art urgently need to solve. Summary of the Invention

[0005] In view of this, the present invention provides a three-dimensional dynamic monitoring method, system and readable storage medium for mining subsidence, which realizes all-round monitoring of mining subsidence while improving the efficiency, accuracy and reliability of data processing.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A three-dimensional dynamic monitoring method for mining subsidence comprises the following steps:

[0008] Construct a corresponding three-dimensional simulation model based on the historical parameters of the target mining area;

[0009] Obtaining ground subsidence information and meteorological and hydrological parameter information of the target mining area in the current period, and inputting the meteorological and hydrological parameter information and the ground subsidence information into the three-dimensional simulation model for simulation;

[0010] Combined with the simulation results and the ground subsidence information, it is determined whether the target mining area has new subsidence, and three-dimensional dynamic monitoring of the mining area subsidence is completed based on the judgment results.

[0011] Preferably, the specific process of determining whether new subsidence occurs in the target mining area includes:

[0012] When new subsidence information appears in the simulation result, determining the location information of the simulation monitoring point where the subsidence information occurs;

[0013] Searching for actual monitoring points corresponding to the location information of the simulated monitoring points in the target mining area, and obtaining elevation data and radar data of the actual monitoring points;

[0014] The elevation data and the radar data are processed, and the processing results are integrated with the ground subsidence information.

[0015] Preferably, the specific process of fusing the processing result with the ground subsidence occurrence information includes:

[0016] Determining the location information and deformation information of the new subsidence according to the ground subsidence occurrence information;

[0017] Determine whether the position information is consistent with the position information of the simulated monitoring point, and if so, obtain a SAR image of the position information and process the SAR image;

[0018] The image processing result of the SAR image is fused with the deformation information.

[0019] Preferably, the specific process of determining whether the location information is consistent with the simulated monitoring point location information further includes:

[0020] When the position information is inconsistent with the position information of the simulation monitoring point, determining the straight-line distance between the two;

[0021] If the straight-line distance is less than a preset threshold, obtaining a SAR image of the location information and processing the SAR image;

[0022] The image processing result of the SAR image is fused with the deformation information.

[0023] Preferably, the specific process of determining whether new ground deformation occurs in the target mining area further includes:

[0024] When the simulation results do not generate new subsidence information, constructing a deformation prediction model;

[0025] Inputting the ground subsidence occurrence information, the meteorological and hydrological parameter information, and the historical parameters of the target mining area in the current period into the deformation prediction model for prediction to obtain a subsidence prediction result;

[0026] Based on the subsidence prediction results, three-dimensional dynamic monitoring of mining area subsidence is completed.

[0027] The present invention also provides a three-dimensional dynamic monitoring system for mining subsidence, comprising:

[0028] Model building module, used to build a corresponding three-dimensional simulation model based on the historical parameters of the target mining area;

[0029] a simulation module for obtaining ground subsidence information and meteorological and hydrological parameter information of a target mining area during a current period, and inputting the meteorological and hydrological parameter information and the ground subsidence information into the three-dimensional simulation model for simulation;

[0030] The monitoring module is used to determine whether new subsidence has occurred in the target mining area by combining the simulation results and the ground subsidence occurrence information, and to complete three-dimensional dynamic monitoring of the mining area subsidence based on the judgment results.

[0031] The present invention also provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the three-dimensional dynamic monitoring method for mining subsidence as described in any one of the above items is implemented.

[0032] It can be seen from the above technical solution that compared with the existing technology, the present invention discloses a three-dimensional dynamic monitoring method, system and readable storage medium for mining area subsidence, which performs simulation based on the three-dimensional simulation model of the target mining area combined with the ground subsidence occurrence information and meteorological and hydrological parameter information of the target mining area in the current period, and judges whether the target mining area has new subsidence in combination with the simulation results and the ground subsidence occurrence information, and completes the three-dimensional dynamic monitoring of the mining area subsidence based on the judgment results, thereby realizing all-round monitoring of the mining area subsidence and improving the efficiency, accuracy and reliability of data processing.

[0039] Obtaining ground subsidence information and meteorological and hydrological parameter information of the target mining area during the current period, and inputting the meteorological and hydrological parameter information and ground subsidence information into a three-dimensional simulation model for simulation;

[0040] Combining the simulation results with the ground subsidence information, it is determined whether the target mining area has new subsidence, and based on the judgment results, the three-dimensional dynamic monitoring of the mining area subsidence is completed.

[0041] In a specific embodiment, the specific process of determining whether new subsidence occurs in the target mining area includes:

[0042] When new subsidence information appears in the simulation results, the location information of the simulation monitoring point where the subsidence information occurs is determined;

[0043] Find the actual monitoring points corresponding to the simulated monitoring point location information in the target mining area, and obtain the elevation data and radar data of the actual monitoring points;

[0044] The elevation data and radar data are processed, and the processing results are integrated with the ground subsidence information.

[0045] In a specific embodiment, the specific process of fusing the processing results with the ground subsidence occurrence information includes:

[0046] Determine the location and deformation information of new subsidence based on the ground subsidence occurrence information;

[0047] Determine whether the location information is consistent with the location information of the simulated monitoring point. If they are consistent, obtain the SAR image of the location information and process the SAR image.

[0048] The image processing results of SAR images are fused with deformation information.

[0049] Specifically, the SAR image processing process may include image cropping and registration, and then generating a corresponding time series interferogram set, and determining the corresponding deformation information based on the time series interferogram set. The above process can improve the corresponding data processing accuracy.

[0050] In a specific embodiment, the specific process of determining whether the location information is consistent with the simulated monitoring point location information further includes:

[0053] The image processing results of SAR images are fused with deformation information.

[0054] Specifically, if the straight-line distance is greater than or equal to a preset threshold, the corresponding simulated deformation information is determined according to the simulation results, and the deformation period and amplitude of the simulated deformation information and the deformation information are analyzed. Based on the analysis results, it is determined whether the two will interfere with each other, and the final deformation impact range and degree are determined based on the judgment results. Because when the mining area reaches a certain range, the buildings or equipment within the mining impact range may be affected. Therefore, judging the deformation impact range helps to obtain the overall deformation degree and improve the reliability of data processing.
