摘要
文章以山西省临汾矿区为例,针对2号煤层及9+10号煤层存在采空积水区的情况,采用可控源音频大地电磁法和瞬变电磁法进行综合电法探测。首先利用可控源音频大地电磁法对构造反映相对明显的优势进行探测,然后结合瞬变电磁法对含水体敏感的特征进行探测,最后两种结果相互补充,进行综合分析解释,准确圈定勘查区内主采煤层采空积水区域及断层等构造的含/富水性,为采空区治理提供科学依据,保证煤矿的安全、高效生产。
This paper, based on a case study on Linfen coal mine, Shanxi province, uses controlled source audio- frequency magnetotelluric method (CSAMT) and transient electromagnetic method (TEM) to detect the water-filling goal in No. 2 and No. 9 + 10 coalbeds. CSAMT is sensitive to structure and TEM is sensitive to water, both are combined in effectively detecting the water-filling goaf and water-bearing faults. This can provide a scientific basis for the management of water-filling goaf, and ensure the safety and efficient production of coal mines.
