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 seam seriously threatens the safety of the coal mines and the occurrence of water-rich areas and the development of water-bearing structures such as faults and fissures, which can effectively guide the prevention and control of water in coal mines. In recent years, mine transient electromagnetic method is widely used in the exploration of coal-rich areas. Compared with other exploration methods, it has the advantages of sensitivity to low-resistivity geological bodies, high resolution in vertical and horizontal directions, large exploration depth and high work efficiency. Combined with the specific work of transient electromagnetic detection in a mine in Shandong Province, this paper proves that the application of mine transient electromagnetic method to detect the water-rich anomalous zone is effective.
