随着煤矿产能大幅提升,采掘主战场向深部的延伸转移,延伸开拓工程所带来的水文地质问题和安全隐患也日益突出,为了保证掘进工作面的施工安全,利用瞬变电磁法,查明掘进巷道前方区域岩层中含水体的空间分布位置及范围,并对含水体的富水性进行评价,圈定出相对富水区,为巷道掘进提供水文地质依据.%With the substantial increase of coal mine production capacity, the extension to the deep of the main mining battlefield is transfered, and the hydrogeological problems and potential safety hazards caused by the extended exploration project have become increasingly prominent. In order to ensure the construction safety of roadway heading, the spatial distribution location and scope of water bodies in the rock strata in front of roadway are determined by transient electromagnetic method. The water-richness of the water body is evaluated and the relative water-rich area is delineated to provide hydrogeological basis for roadway driving.
