Abstract:Qiwu coal mine is the main production coal mine of Zaozhuang mining group. Its geological conditions are very complex. Faults well developed widely. Scouring, subsidence, goaf and magmatic intrusion occurred in No.3 mining layer, which have a great impact on the layout of roadways and workspace in the next step. Beiqi mining area is the continuous mining area of Qiwu coal mine. It is urgent to investigate geological structures and the occurrence of coal layers in the area. By the combination of comprehensive interpretation of conventional seismic time profiles and seismic attributes with the borehole data, the occurrence boundaries of the above-mentioned geological phenomena in the three coal layers in the area have been identified. Later roadway exposures are in good agreement with the results of three-dimensional seismic interpretation, and good application results have been achieved.
