A coal seam target geological structure identification method, system and device

This application discloses a method, system, and device for identifying target geological structures in coal seams. The target geological structures include folds, faults, lower local thickening zones, and upper local thickening zones. The method acquires full measured data of cross-layer boreholes in the target longwall face, along with the strike, dip, and true dip parameters of the coal seam. Preprocessing yields the three-dimensional coordinates of the borehole entry point, the three-dimensional coordinates of the exit point, and the true thickness of the coal seam. A square nine-grid analysis window is constructed with the strike and dip of the coal seam as the directional reference. Target cross-layer boreholes with stable coal seam thickness are selected based on the deviation of the true thickness of the coal seam. A spatial plane equation of the coal seam is established to calculate the theoretical entry point elevation of the target cross-layer borehole, generating regional target geological structure identification results. A sliding window traverses the entire longwall face, outputting the overall regional target geological structure identification results. This method can stably identify hidden small target geological structures and significantly improves computational efficiency compared to traditional methods. It can be widely applied to advanced geological exploration scenarios in coal mine longwall faces.
