摘要
文中介绍了矿井瞬变电磁探测技术的原理与方法,以济宁某煤矿4318工作面为例,采用瞬变电磁法对煤层顶、底板含水层富水性进行探测,获得测线的视电阻率剖面图,并根据视电阻率剖面图进行全面分析、判断,阐明超前探测范围内水文地质情况,为巷道安全掘进提供依据。
In this paper, the principle and the method of mine transient electromagnetic detection technology were introduced. Taking the 4318 working face of a coal mine in Jining as an example, the transient electromagnetic method was used to detect the water-rich water of the top aquifer and bottom aquifer of the coal seam, and the apparent resistivity profiles of the line were obtained. Hydrogeological conditions were analyzed, judged and clarified according to the apparent resistivity profiles within the pre-detection range providing the geological data for safe tunneling.
