瞬变电磁法在煤矿富水区探测中的应用研究

Application of Transient Electromagnetic Method in Detection of Water-rich Areas in Coal Mines

旗山煤矿地处水文条件复杂的贾汪区境内,南距京杭大运河仅2km,2010年曾发生过一起较为严重的突水事故,为保证旗山煤矿后续煤层的安全开采,解放更多的受水威胁的煤炭资源,在采区巷道开拓前,利用矿井瞬变电磁立体探测技术,查明含水层位置及对巷道安全的威胁程度,为煤矿现场防治水工作提供借鉴。

Qishan Coal Mine is located in Jiawang District with complicated hydrological conditions. It is only 2 km south from the Grand Canal of Beijing and Hangzhou. A serious water inrush accident occurred in 2010. In order to ensure the safe mining of the following coal seams in Qishan Coal Mine and liberate more coal resources threatened by water, the mine transient electromagnetic stereoscopic prospecting was used before the roadway development in the mining area. Measuring technology is used to ascertain the position of aquifer and the degree of threat to the safety of roadway, which can provide a reference for the prevention and control of water in coal mine.
