摘要
针对桑树坪煤矿40年以来奥灰岩6号涌水点治理技术难题,通过水文地质调查分析入手,开展了挡水墙与围岩松动圈加固和引水利用技术研究,优化治理方案和施工措施,经过对挡水墙周围裂隙、管路接口反复注浆试验与技术创新,使岩石裂缝与管路接茬漏水得到彻底治理,堵水率达到99.1%,节能减排成效十分显著,有效提升了矿井抗水灾能力。
Aiming at the technical problems of controlling No.6 water inflow point of Ordovician limestone in Sangshuping Coal Mine in the past 40 years,through the analysis of hydrogeological survey,the reinforcement and water diversion technology of water retaining wall and surrounding rock loose ring is studied,the treatment scheme and construction measures are optimized,and repeated grouting tests and technical innovations are made on cracks around water retaining wall and pipeline interface.Rock cracks and pipeline leaking water were thoroughly treated,water plugging rate reached 99.1%,energy saving and emission reduction effect is very significant,which effectively improves the mine flood resistance.
