瞬变电磁法与钻探结合确定含水区技术分析

Analysis on Aquifer Region Determining Technology by Transient Electromagnetic Method Combined with Drilling Exploration

针对巷道掘进面前方水文地质条件的变化,采用瞬变电磁法进行超前探测、辅助钻孔探测确定异常区的方法,能对含水区域位置、范围等进行准确预报。瞬变探测技术的应用,为制订合理防治水措施提供了依据。

Aiming at the change of hydrogeological conditions on roadway drivage face,the method was thought to make accurate detec- tion on the location of water in-rich regions and its range, that is, transient electromagnetic method applied for advanced detection, and detecting some auxiliary holes used to determine abnormal area. The application of transient detection technology can provide basis for planning reasonable water control measures.
