摘要
本文首先介绍了矿井直流电超前探测方法的原理和施工技术,然后针对在平朔安家岭一号井工矿太西区4煤回风大巷的掘进过程中,利用该技术进行了超前探测跟踪的实例分析,结果表明,该技术对掘进头前方的水文地质异常区定位探测准确,可以指导煤矿的安全掘进,保障安全生产。
This paper first introduces the principles and project technique of mine DC advanced detection meihed, then makes an analysis of using this technology according to the heading, in the air shaft in Taixi area 4^# coal, Anjialing No. 1 mine,Pingsuo.Tne results show that this technology is very accuracy to position detection at unusual hydrogeological area in front of heading,can guide safe tunneling of coal mine and ensure the safe production.
