Abstract In order to accurately identify all kinds of geological factors hiddenly causing damage in the north second mining area of Sangshuping Coal Mine, based on the exploration results of three-dimensional seismic exploration and transient electromagnetic comprehensive physical exploration method, the geological anomalies in the study area were comprehensively analyzed and evaluated, which provided a basis for the safe production of the north second mining area in the future.The structural form of No. 3 coal seam in the north second mining area was identified,11 new deflections were exposed, 16 fractures were interpreted, two goaf boundary and its influence area of No.3 coal seams in the area were identified,the water condition of No.3 coal seam roof and floor aquifer in north second mining area was identified, and five water abundance areas were interpreted. The undulating form and water abundance of Ordovician limestone aquifer were interpreted; two layer slip structures were interpreted.
