摘　　要：本文针对某矿井12#层410盘区51045巷在掘进过程中可能存在小窑破坏区积水的难题,在原有瞬变电磁超前物探的基础上,提出了采用多次瞬变超前物探解释成果叠加的综合解释方法,根据成果的公共异常区,指导超前探孔的设计,达到降低体积效应的目的,探测结果与钻探验证情况基本吻合,取得了良好的应用效果,提高瞬变超前物探探测精度,为巷道的安全高效掘进提供可靠依据。In view of the problem that there may be goaf water in 51045 tunnel at 410 panel area of No.12 coal seam,on the basis of the original TEM advanced geophysical exploration,a comprehensive interpretation method based on the superposition of multiple transient geophysical interpretation results is proposed,according to the results of the public abnormal area, guide the design of the advance exploration hole, achieve the purpose of reducing the volume effect, the detection results are basically consistent with the drilling verification, and achieve good application effect, improve the detection accuracy of the transient advance geophysical exploration, and provide a reliable basis for the safe and efficient tunneling of the tunnel.
