Abstract：In order to identify the scope of geological hazards such as ground subsidence,subsidence,and ground fissures,two geophysical methods,high-density electrical method and micro motion detection were selected for exploration.The field observation data were preprocessed and inverted to produce apparent resistivity isopleth sec-tions and apparent shear wave velocity sections.Based on the geophysical results,anomalies were delineated.By integrating the delineated geophysical anomalies with geological survey results and previous geological data around the working area,the surface distribution range and depth of damage in the ground deformation area within the working area are inferred.
