摘要: 介绍了全空间瞬变电磁(UWTEM)技术在煤矿井下探测老空水方面的应用,研究了井下巷道有限施工条件下探测不同赋存方位采空区的方法,证明了UWTEM技术在探测巷道掘进头前方、巷道顶底板及巷道侧帮等方向老空水的有效性,总结了井下瞬变电磁技术应用中需注意的若干关键问题。结果表明,UWTEM技术能在井下有效地探测巷道顶底板、侧帮及掘进头前方的老空水位置和范围,为井下水害预报和防治提供可靠依据。

Abstract: This paper introduces the application of Underground Whole-space Transient Electromagnetic Method(UWTEM)to the detection of abandoned mine water.It presents the study of the method to detect different occurrence goaves in limited work conditions.It proves the effectiveness of UWTEM technology in detecting goaf water ahead of the tunneling,or in the roof,floor and sides of the roadway.It concludes several key issues which require notice in the application of UWTEM.The result shows that UWTEM technology can effectively detect both the position and extent of goaf water ahead of the tunneling,or in the roof,floor and sides of the roadway.It also provides reliable basis for prediction and prevention of mine water disasters.

Key words: Transient Electromagnetic Method(TEM), underground, goaf water, coalmine, application
