瞬变电磁技术探测采空区及顶板含水性的应用

Application of Transient Electromagnetic Technology in Exploring Water-bearing Property in Goaf and Roof

为精准有效的对裕泰煤业3#、15#煤层采空区及顶板岩层的含水性进行评价,通过对采空区积水水源和聚水区域的分析,结合本井田的具体地质情况,采用瞬变电磁技术对井田范围进行物探作业,并对探测结果进行处理分析。结果表明:3#煤层采空区及顶板存在9个含水异常区,15#煤层采空区及顶板存在7个含水异常区。

In order to accurately and effectively evaluate the water-bearing property of the goaf and roof strata in No. 3 and No. 15 coal seam, Yutai Coal Industry, the water source and gathering water area of the goaf are analysed in the paper, combined with the specific geological conditions of this mine field, the transient electromagnetic technology is adopted to conduct geophysical exploration of the mine field range, and the detection results are also processed and analysed. Results show that there are 9 water-bearing abnormal areas in goaf and roof of No. 3 coal seam, and 7 water-bearing abnormal areas in goaf and roof of No. 15 coal seam.
