With the deepening of coal mining,coal mine flooding accidents are increasing,which seriously affects the construction safety of working faces.In order to realize the safety production of 3310 mining face,three-dimensional parallel electrical method was used to detect the water content of coal rock layers in the coal mine,and three-dimensional resistivity inversion technology was used to obtain the distribution pattern of coal seam roof and floor rock face.The test results showed that the water inflow in several goaf areas was only 0.5 m3/h when the potential distribution map obtained by resistivity inversion technique was used to relieve the water,realizing the safe mining of the working face.
