摘　　要：峪沟煤业4号煤层一采区8105工作面属于带压开采区域,回采期间受到临近DF2断层破碎带影响底板涌水,为解决该矿生产过程中滞后突水的威胁,通过理论分析、电法探测和注浆加固对断层导水治理及防治水技术进行研究,确定了工作面回采治理前后涌水量、断层治理前后裂隙涌水量变化,经过底板注浆加固堵水后,治理效果明显,回采期间水量明显减小,回采后未发生滞后突水现象,实现了工作面安全高效回采。The No.8105 face in the No.1 mining area of No.4 layer of Yugou Coal Industry belongs to the mining area under pressure.During the mining period,it was threatened by the floor water inflow affected by the adjacent DF2 fault fracture zone.In order to solve the threat of lagging water outburst in the production process of the mine,the fault water conduction control and water prevention technology were studied through theoretical analysis,electrical detection and grouting reinforcement.The change of water inflow before and after the mining treatment of the working face and the change of fissure water inflow before and after the fault treatment were determined.After the floor grouting reinforcement for water plugging,the treatment effect was obvious,the water volume during the mining period was obviously reduced,and there was no lagging water outburst phenomenon after the mining,which realized the safe and efficient mining of the working face.
