| 摘 要： | 介绍了地质雷达法、电磁波CT成像法及瞬变电磁法在探测煤矿采空区覆岩“两带”的应用。认为地球物理勘探方法在观测钻孔不足或冲洗液消耗量法不能顺利进行时能有效地探测煤矿采空区覆岩“两带”，特别是瞬变电磁法有分辨率高，抗干扰性强的特点，值得推广。

| Abstract: | In this paper, the applications of the geophysical prospecting mthods, i. e. Geological Prospecting Radar (GRP), Computer Tomographic Technique (CT) and Transient Electromagnetic Method (TEM) in determining the caving zone and the water flowing fractured zone in cover strata in mine goaf were introduced. It has been considered effective that determining the caving zone and the water flowing fractured zone by geophysical prospecting methods when other methods are impossible. Especially, TEM is a method with high resolution ratio and strong power of anti-disturbance. |
