| 摘 要： | 瞬变电磁法是目前工程勘察中应用较广的物探工作方法。尤其大回线源瞬变电磁法，由于发、收位于同一点，在近场测量，不存在体积效应，故分辨率高，特别是横向分辨率更高，可分辨出地下规模较小的不均匀体。笔者将瞬变电磁法用于甘肃华亭煤矿保安煤柱探测及宁夏灵武矿区圈定老窑采空区，资料清晰地反映出采空区的分布范围和保安煤柱的位置

| 关 键 词： | 瞬变电磁法，工程勘察，采空区煤柱 |

| Abstract: | Large loop TEMS is one method, used widely in engineering prospecting. Because of sending and receiving of signal being in the same point,it belongs to nearer field method without volume effect,it is of higher resolution especially the transversal resolution is so high that the underground body with smaller size may be distinguished.This TEMS has been applied to detect the position of areas mined out and coal column,the result of analysing original data show the distributions of area mined out and the position of coal column clearly. |
