摘要
为达到杨柳矿井副井井筒基岩段堵水及对不稳定地层加固的目的,并最终实现井筒安全快速掘进,杨柳矿井副井井筒采用了地面预注浆施工技术。本文着重介绍了井筒地面预注浆施工的技术方案、注浆工艺、注浆经验及取得的良好技术经济效果。
In order to reach the goat of blocking water at basic rock and bearing ground and stabilizing the unstable layer auxiliary shaft of Yangliu Coal Mine, and realize safe production finally pre - cementation method is used. This paper focuses on the design, method, acquired experience and satisfactory outcomes both in technology and economy benefit of pre - cementation.
