摘　　要：为了解决卜弋煤矿遗留下来的采空区问题,本文在收集卜弋煤矿采掘资料的基础上,分析采空区的电性特征和埋藏深度,通过地球物理方法选择瞬变电磁勘探技术来进行采空区的探测。结果表明,瞬变电磁对探测煤矿遗留采空区具有较好的效果,采空区在电性剖面上具有明显的低阻特征,根据电性特征可以很好地圈定采空区的分布范围。In order to solve the problem of goaf remained by Buyi Coal Mine,this article analyzes the electrical characteristics and burial depth of the goaf based on the collection of mining data from Buyi Coal Mine.Through geophysical method,transient electromagnetic exploration technology is selected to detect the goaf.The results show that transient electromagnetic has a good effect on detecting the remaining goaf in coal mines.The goaf has obvious low resistance characteristics on the electrical profile,and the distribution range of the goaf can be well delineated based on the electrical characteristics.
