摘　　要：为了探测福山铜矿王家庄矿区采空区具体位置,采用高密度电阻率法和瞬变电磁法,对采空区内进行地球物理测量,利用采集区内岩体电性参数,结合已知的工程地质资料及此次物探测量成果,对采空区或巷道所产生的地球物理特征进行了系统的对比分析,划分出了6处重点异常区。研究为后续工程地质钻探验证等工作提供了参考依据。In order to detect the specific location of the mined-out area in the Wangjiazhuang mining area of Fushan Copper Mine,the high-density resistivity method and the transient electromagnetic method were used to conduct geophysical measurements in the mined-out area,and the electrical parameters of the rock mass in the collected area were combined with the known engineering geological data and the results of this physical detection had systematically compared and analyzed the geophysical characteristics produced by the mined-out areas or roadways,and divided 6 key abnormal areas.The research provided a basic reference for the follow-up engineering geological drilling verification and other work.
