瞬变电磁法在探测煤田采空区积水中的应用

The Application of Transient Electromagnetic Method in Detecting the Accumulated Water in Worked-out Section of Coal Field

在介绍测区地质概况的基础上,利用瞬变电磁法对同煤集团塔山煤矿采空区及采空积水区进行探测,在已知地质钻孔附近进行了参数选择实验,并根据高阻为采空区,特低阻为采空积水的地球物理原则,指导后期资料解释。

Based on introducing the geologic aspects of the survey area, this paper detects the worked-out section and accumulated water in worked-out section of Tashan Coal Mine of Datong Coal Industry Group by using the transient electromagnetic method, and makes the parameter choice experiment near the known geological boreholes, and guides the sequel data interpretation according to the principle of that the high electric resistivity is worked-out section and especially low electric resistivity is accumulated water in worked-out section.
