由于特殊的井下施工环境,矿井瞬变电磁法与地面瞬变电磁法以及其他的矿井物探方法有很大的不同,受井下巷道施工空间所限,只能采用边长小于3 m的多匝小线框。该文通过介绍井下瞬变电磁法勘探技术在采区工作面上覆地层的富水情况的应用效果,说明该种物探方法可以为探放水工作提供科学依据。

Due to the special construction of underground environment, mine transient variable electromagnetic method have very different from the ground transient electromagnetic method and other mine geophysical prospecting methods, by the limited space in underground roadway, only the use of side length less than 3m multi turn small line box, this paper introduced the application effect of mine transient electromagnetic method exploration technology in coal mining face of water rich strata, that showed the geophysical methods can provide scientiifc basis for exploration and discharging work.
