Application of Nanometer Transient Electromagnetic Method in Exploring Shallow Gob of Coal Mine

摘要: 综合地面物探瞬变电磁法的应用发展技术,根据探测区的地球物理特征电性差异,运用GDP-32^Ⅱ多功能电法仪,以纳米瞬变电磁法探测某煤矿浅层采空区为例,通过对实测资料的处理及拟视电阻率断面图、平面等值线图的综合分析,准确地探测出了该区域采空区的分布位置,说明应用GDP-32^Ⅱ多功能电法仪以纳米瞬变电磁法探测煤矿浅层采空区是可行的。

Abstract: Applying GDP-32^Ⅱ multi-function receiver system,shallow gobs of a mine was explored based on the difference of electrical property in exploration area. The gob distribution places in this area were precisely located by analyzing apparent resistivity section maps and planar contours,which showed that applying GDP-32^Ⅱ multi-function receiver system to exploring shallow gob was feasible.
