摘要
淮北某煤矿因第四含水层水量过大,通过F5断层导入采煤工作面,使采煤生产陷入停顿。为解决采煤工作面涌水量过大问题,研制了高浓度化学浆液,经钻孔注浆收到良好的止水效果,使近200万t煤炭资源恢复开采,取得了很好的经济和社会效益。
Because large amount of water in the fourth aquifer of a coal mine in Huaibei,water was introduced into the coalface through F5 fault with serious influence to the production.High concentration chemical slurry was developed to solve the problem and restart mining by borehole grouting with good effect.
