Problems solved by technology
[0003] The submission of the report on the results of 3D seismic processing and interpretation in existing coal mines is one-time, but with the mining of coal mines and the excavation of roadways, almost all seismic prediction data can be verified, but the actual data revealed are rarely compared with the original data. This makes it difficult to effectively improve the accuracy of 3D seismic processing and interpretation, which seriously restricts the development of 3D seismic technology and makes it difficult to meet the needs of industrialized coal mining

The present invention discloses a mine three-dimensional seismic full process geological exploration prediction method, relating to the technical field of underground coal seam exploration. The method comprises a step of using a three-dimensional seismic exploration method to delineate whether a minable coal layer bit has a concealed geological structure, a step of carrying out real-time verification and analysis evaluation on the result of three-dimensional seismic exploration with the actual roadway disclosure and drilling result as constraints, and a step of fusing the verified and analyzed minable coal layer geological information into the three-dimensional seismic exploration result, using an iterative feedback method, carrying out re-processing, re-interpretation and re-application on an exploration area result which is not in accordance with a detection precision requirement, constantly changing the constraints, and finally forming a mine three-dimensional seismic full process geological analysis result. According to the method, the accuracy of the three-dimensional seismic processing and interpretation can be effectively improved, the geological construction condition in mining influence range can be predicted and found to the maximum, the roadway mining area arrangement is facilitated, and the safety accidents can be scientifically and effectively prevented and reduced.
Description
technical field [0001] The invention relates to the technical field of underground coal seam exploration, in particular to a mine three-dimensional seismic whole-process geological exploration prediction method. Background technique [0002] Coal mine 3D seismic is an exploration technology developed by the comprehensive utilization of multiple disciplines. As an above-ground exploration technology, 3D seismic can detect the geological structure of the mine in advance and accurately describe the distribution range of faults and collapsed columns before the construction of the mine and before the tunneling. , to provide geological basis for mine planning, mining area design and roadway layout, optimize the overall layout and improve production efficiency. Under the condition of unknown geological conditions, roadway excavation is prone to safety accidents, serious casualties and huge economic losses. The use of 3D seismic technology can effectively grasp the characteristics o...
