高浓度化学浆液的研制与应用效果

Development of High Concentration Chemical Slurry and the Application Effect

摘要:

淮北某煤矿因第四含水层水量过大，通过F5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。

Abstract:

Because large amount of water in the fourth aquifer of a coal mine in Huaibei, water was introduced into the coalface through F5 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.
