In order to solve the problem that the terrain of talahao coal mine is complex and the thickness of loess changes greatly laterally, resulting in the low signal-to-noise ratio of regional seismic data, and the accuracy of previous results can not meet the production guidance of the mine field, the signal-to-noise ratio and resolution of data are greatly improved by reasonable processing method, process and parameter selection on the premise of fidelity, and the final interpretation results (faults, roadways) are compared with mining results The accuracy of exposure is improved significantly, which provides a reliable basis for the safe mining of coal mines, and summarizes the technical methods suitable for the fine 3D seismic exploration processing in this area.
