瞬变电磁法在矿井水害治理工作中的应用

平煤集团七矿属大水矿井，每年仅排水一项就耗资巨大．给煤矿的经济发展和安全生产带来了极大的风险。为了彻底治理矿井水害，七矿采用瞬变电磁勘探技术．查明了地表水涌入矿井的三条通道，划出了L6、L7灰岩的岩溶裂隙富水区及其二者的水力联系，从而有的放矢地实施帷幕注浆截流治水工程。七矿的注浆工程实践充分验证了瞬变电磁勘探成果的准确性。

THE APPLICATION OF TRANSIENT ELECTROMAGNETIC METHOD IN THE WORK OF MINE FLOOD DAMAGE CONTROL

The 7^th coal mine of Pingdingshan Coal Group is abundant in underground water. It is an enormous risk for coal production and a great burden for the development of the 7^th coal mine. In order to resolve these underground water problems , the TEM exploration was introduced. Three underground watercourse were found and the watery zones in Limestone 7 and Limestone 6 were plot out through the exploration. The correctness of the exploration result was approved by late engineering of the 7^th coal mine.
