中文摘要：

峰峰矿区矿井水文地质条件复杂,受水害威胁大,对工作面底板隐伏构造及导水性的排查和处理是其亟待解决的问题。采用地震勘探法,对峰峰矿区某矿182311工作面前方小断层等隐伏导水构造进行了超前探测,查明在工作面前方约49 m位置存在明显波阻抗异常,通过钻探验证,其前方50 m见一导水异常区,实际揭露为落差0.8 m的小断层,超前探测结果与实际情况基本相符。可为导水构造地段进行注浆改造、加固处理,消除突水隐患提供技术保障。

英文摘要：

Fengfeng Coal Mining Area has complicated hydro-geological conditions and is threatened by water flood,so an urgent problem to be solved is to investigate and handle the concealed structures in the working face and their hydraulic conductivity. Advance detection was carried out on the concealed structures such as the small faults in front of 182311 working face in a mine in Fengfeng Mining Area,it was found out through investigations that there was an obvious wave- resistance abnormally at the place about 49 m in front of the working face,the exploratory boring proved that there was an abnormal water flowing zone at the place 50 m in front of the face,the actual revelation was a small fault with the throw of 0. 8 m,and the advance detection results were basically consistent with actual situation. This detection can provide technical support for the grouting reconstruction and reinforcement and the elimination of water inrush hazard in the water flowing structural zone.
