摘　　要：介绍了矿井瞬变电磁超前探测技术的原理与方法,并以庞庞塔煤矿的10-702工作面上覆老空积水探测为例,采用该技术进行了超前探测;在此基础上,设计疏放水工程对积水异常区进行疏放,累积放水量达到47.58万m3,有效地消除了该工作面上方5#煤老空积水。This paper introduced the principle and method of coal mine transient electromagnetic advanced detection technology, taking the overlying old gob water detection in Pangpangta coal mine 10 -702 working face as an example, the advanced detection was carried out by using this technology. On this basis, dredging and draining water project was designed to dredge and drain water in abnormal ar- ea, and the accumulation of water flowage was up to 475800 m3, which effectively eliminated the 5# gob water above the working face.
