摘　　要：杨涧煤矿90102工作面底板隔水层厚度约50 m,底板奥灰水压约1.3 MPa,工作面揭露5个陷落柱,先后出现顶板淋水、底板涌水、底鼓等现象,为确保工作面安全开采,提出了陷落柱探查-导水性研究-注浆堵截的陷落柱防治技术理论体系。在充分分析研究区水文地质条件、排查水害隐患的基础上,采用瞬变电磁探测技术、三维地震动态解释技术对含水层富水性、断层及陷落柱等构造的富水性、导水性质进行探测研究,同时以带压开采研究为突破口,开展矿井注浆加固底板及封堵突水通道技术应用研究。该研究对完善矿井防治水体系,严防矿井水害发生、确保矿井的安全生产,对平朔矿区华北型煤田构造探查治理工作具有重要的借鉴意义。On the No.90102 working face in Yangjian Mine,the floor aquifuge is about 50 m in thickness and Ordovician limestone water pressure is about 1.3 MPa;5 collapse columns are exposed with roof drenching,floor gushing,and floor heave appearing successively.To ensure the safe mining of the working face,this paper puts forward a theoretical system of collapse column prevention and control technology combining the collapse column exploration,hydraulic conductivity study,and plugging by grouting.Based on analyzing hydrogeological conditions and checking water hazards,transient electromagnetic detection and 3D seismic dynamic interpretation technology were used to explore the water-abundance of aquifers and the water abundance and conductivity of faults and collapse columns.Meanwhile,taking pressure mining as a breakthrough,we carried out the application research of grouting reinforcement of floor and plugging of water inrush channels in the mine.This research is of great significance to improve the water control system,prevent water hazards,ensure safe production,and explore the tectonic structure of North China-type coalfield in Pingshuo mining area.
