昌华煤矿副立井过含水层防治水技术研究

Research of prevention and control technology of water during the construction of Changhua coal mine sub-shaft

结合昌华煤矿副立井注浆防治水施工的实践,对于通过含水层为孔隙水与裂隙水的地质条件,采用普通水泥浆液、超细水泥浆液与化学浆液共同作用,有效地控制了注浆量与注浆压力,达到了理想的注浆防治水效果。

Integrating with prevention and control water construction practice of sub-shaft grouting of Changhua coal mine,based on the geological condition of moisture with pore water and fissure water,the paper applies mutual action of common cement slurry,super-fine cement slurry and chemical slurry,and effectively control the grouting amount and grouting pressure,and finally achieve ideal of the grouting effect of prevention and control water.
