摘　　要：随着煤矿开采深入,煤矿透水事故不断增加,严重影响工作面的施工安全。为实现3310回采工作面安全生产,采用三维并行电法探测矿山煤岩层含水率情况,利用三维电阻率反演技术得到煤层顶底板岩面分布形态。试验结果表明,根据电阻率反演技术得到的电位分布图对多个采空区积水进行疏放,涌水量仅为0.5 m^(3)/h,实现了工作面的安全开采。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 m^(3)/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.
