In order to support the geological environment investigation and mine environment restoration and management in coal mining goaf area, the research and application demonstration of comprehensive geophysical exploration technology method were carried out in the typical coal mining goaf area of Yangquan mining area,Shanxi Province. Through gravity exploration, shallow seismic method and transient electromagnetic method, the comparative application of geophysical methods in the coal mining goaf is studied, and the specific model of goaf exploration of coal field by combining the above three geophysical methods is summarized. The exploration results show that the comprehensive geophysical exploration combined with the ground geological survey can identify the attribute information such as the boundary and depth of the goaf, and provide the data basis for the 3D geological modeling of the goaf.
