矿井瞬变电磁法在整合矿井老空及灰岩水探测中的应用

瑞龙煤矿为资源整合矿井,150104工作面为瑞龙煤矿的首采工作面,工作面上方存有老空水及灰岩水,对工作面的安全形成了威胁,针对上述问题,采用矿井瞬变电磁对工作面上方老空区积水和灰岩赋水情况进行了探测,查明了老空水和顶板灰岩水的富水区的分布情况,确定了4个异常区并对异常区进行了探放水,消除了水害威胁,保证了矿井安全。

Application of Mine Transient Electromagnetic Method to Detect the Golf and Limestone Water in Integrated Mine

The Ruilong mine Co. Ltd. is an integrated mine in Shanxi province. The golf and limestone water lies above the NO.15 104 mining face is a serious threat to the safety production of Ruilongcoal mine.In order to ensure mining safety,the mine transient electromagnetic method was used to detect the occurrence of the golf water and limestone water. Four water abnormal zones were pointed out and water detection and drainage was done in these zones. The results show that the conclusion of mine transient electromagnetic method was in ac-cordance with the water occurrence in the golf and limestone above the mining face. The achievement of the mine transient electromagnetic method provides thescientific basis to prevent water disaster of the mine in the fu-ture.
