瞬变电磁和直流电法超前物探的对比研究

Comparative Study of Transient Electromagnetic Method and Direct Current Method in Advanced Geophysical Prospecting

针对带压开采煤矿中存在老空水水体隐患问题,对巷道进行超前探显得尤为必要。目前,超前物探技术主要包括瞬变电磁和直流电法两种探测技术。本文以同煤某I型煤矿和同煤某II型煤矿为应用研究煤矿,首先介绍了这两种探测技术对两个煤矿的探测结果,结合探测技术原理,通过对比两种探测方法对于探测效果的分析,对这两种方法各自的优缺点展开了详细的研究,为后续开采煤矿中水体灾害的防治有指导意义。

In view of the hidden danger of goaf water body in coal mine with pressure mining,it is necessary to carry out advanced exploration of roadway.At present,advanced geophysical exploration technology mainly includes transient electromagnetic and direct current detection technology.In this paper,a certain type I coal mine and a certain type II coal mine in Datong Coal Mine Group are taken as the application research coal mine.Firstly,the detection results of these two detection technologies for the two coal mines are introduced.Combined with the detection technology principle,the advantages and disadvantages of the two detection methods are analyzed in detail,which provides guidance for the prevention and control of water disasters in subsequent mining coal mines significance.
