物探技术在悦昌煤矿防治水中的应用研究

Application Research on Geophysical Prospecting Technique in Water Control in Yuechang Colliery

悦昌煤业开采的1#、2#煤层为近距离煤层,地质及水文地质条件复杂。为超前探明1-101首采工作面地质构造及小窑破坏区范围,采用了矿井瞬变电磁法、探地雷达、音频电透视法等综合物探技术对1-101首采工作面进行地质探查,查明了工作面隐伏导水构造及小窑采空破坏区范围,为工作面的防治水工作提供了充足的地质依据。

Being close--distance coal seam, the geological and hydrogeological condition of 1 # and 2# coal seam in Yuechang Coal Industry Co. is complex. In order to detect in advance of geological structure of 1--101 first min ing working face and the scope of small coal pits failure zone,comprehensive geophysical prospecting technologies with coal mine transient electromagnetic method,ground penetrating radar and audio--frequency electrical penetration method have been used to detect 1--101 first mining working face,which have found out the hidden water conductivity structure of the face and the scope of small coal pits failure zone and provided adequate geological evidence for water control in the face.
