摘要
本文通过实例介绍了矿井瞬变电磁法超前探测的基本原理及井下施工技术。实际应用表明,该方法对解决巷道掘进迎头方向的水害隐患及确保巷道安全是一种快捷、有效的勘查手段,可以为煤矿地质保障系统提供重要的技术依据。
In this paper,the basic principle and downhole construction technology of advanced detection by transient electromagnetic method are introduced through some examples.The practical application shows that is a quick and effective method to solve water damage of the drilling head direction in tunnel driving and to ensure tunnel safety,which can provide essential technical basis for the coal exploration.
