摘　　要：矿山地质灾害包括岩溶透水害、封闭不良钻孔透水、采空区、不良工程地质体等。要严格防控矿山地质灾害发生、遏制重大安全风险并坚决防范事故发生,需进一步查明矿区范围采空区分布形态、积水情况、岩溶及地下水赋存情况、导水裂缝带、封闭不良钻孔情况等。本文采用瞬变电磁探测法通过视电阻率值高低对应的地质特征,结合现场实际情况综合分析不良地质体的分布情况,为下一步的地质灾害治理提供依据。The geological hazards in mines include karst water seepage,sealing poor drilling water seepage,goaf,and poor engineering geological body.The occurrence of geological hazards in mines should be strictly controlled to contain major safety risks,in order to prevent accidents,it is necessary to find out the distribution of mined-out area,water accumulation,karst and groundwater occurrence,water-conducting fracture zone and bad sealing borehole.In this paper,transient electromagnetic detection method is used to analyze the distribution of bad geological bodies according to the geological characteristics of apparent resistivity and the actual situation in the field.
