为了探查凯川矿西部采空区及积水赋存情况，利用地面瞬变电磁探测技术对目标区域采空区积水的位置及范围进行探测，通过分析等视电阻率断面图、顺层切片图，采空区及采空积水区引起的视电阻率异常区电性反映较明显，并采用瞬变电磁法与激发极化法相互印证，对采空积水区位置、范围及深度进行了分析解释，根据成果报告，提前对采空区采取了验证、疏放措施，有效消除了水害威胁，降低了将来采掘工程的水害风险，收到了较好的经济技术效果。

 In order to explore the occurrence of goaf and water accumulation in the west of Kaichuan Mine, the ground transient electromagnetic detection technology was used to detect the location and range of water accumulation in the goaf of the target area. By analyzing the cross section of the apparent resistivity and the bedding slice diagram, the electrical reflection of the apparent resistivity anomaly area caused by the goaf and accumulated water area in goaf was relatively obvious. The transient electromagnetic method and the induced polarization method were used to verify each other, and the location, range and depth of accumulated water area in goaf were analyzed and explained. According to the results report, the verification and drainage measures were taken in advance for the goaf, which effectively eliminated the threat of water damage and reduced the risk of water damage in the future mining project. The application received good economic and technical effects.
