瞬变电磁法在煤矿富水区探测中的应用

Application of Prospecting Water-rich Area of Coal with TEM

煤层的富水区严重威胁着煤矿的生产安全,探明富水区的赋存和断层、裂隙等导含水构造的发育情况,可以有效地指导煤矿的防治水工作。矿井瞬变电磁法近些年来广泛应用于煤矿富水区的探查,与其它探测方法相比,它具有对低阻地质体反映灵敏,纵横向辨率高,勘探深度大,工作效率高等优势。本文结合在山东某矿瞬变电磁探测的具体工作,证明应用矿井瞬变电磁法探测富水异常区效果良好。

The water-rich area of the coal has a serious threat to the safety of coal mine production.To prospect occurrence of the water-rich region and the development of water structure of the fault,fracture and other structures of containing and conducting water can effectively guide the work of mine water control.TEM in recent years has been widely used in exploration of water-rich coal area.In comparison with other detecting methods,it has the advantages of a sensitive reflection to the geological bodies of the low resistivity,the high resolution of vertical and horizontal,the deep exploration and the high work efficiency.In this paper,combining the specific work of transient electromagnetic exploration of a mine in Shandong,it tries to prove the mine TEM has a good effect to detect the abnormal areas with the water-rich.
