Abstract
4D seismic monitoring in goaf of coal mine is significantly different from that in oil and gas field development. Except for the change of coal seam being mined out, the physical properties of surface and underground rocks have changed greatly due to the collapse of overlying strata in goaf. Based on two 3D seismic data spanning five years, we studied the 4D seismic monitoring methods of goaf variation range, mining speed and mining mode, and proposed a set of 4D seismic data processing and interpretation methods for goaf in coal mine. The results coincide with the information of goaf and coal mining in exploration area.
