Based on the seismic geological conditions, field test results and the adjacent mining area construction experience, through reasoning in many ways , 3 d seismic exploration method was settled to find out the structure and development of some mining area. Through seismic data processing and data interpretation, the exploration area of time section of fault and fold structure performance characteristics and space distribution rule were studied, finally the exploration and development in the area was found with 11 fault, 1 syncline structure, goaf in 2 places was settled.
