摘要
简要介绍了瞬变电磁超前探测技术的原理与方法,及某矿二水平皮带下山和13皮带上山2个掘进工作面前方80 m范围内岩层赋水情况进行多角度、多方位的探测,探讨了瞬变电磁法的应用效果,并提出了防治水的建议,为巷道安全掘进、避免严重水害事故的发生提供参考依据。
The principles of transient electromagnetic method（TEM）,and multi-angle,multi-directional detection of rock water stadus in the rang of 80m at front of two levels belt down-hll and 13 belt up-hill are briefly introduced in this paper.The effect of TME method is analyzed,the proposals are proposed to preventi and control water,and the reference is provided to avoid the occurrence of water disaster and roadway＇s security excavation.
