摘要
以西部某冻结井筒壁后注浆工程为例,对壁后注浆时间进行了介绍,分析说明了注浆孔的布置方式,并对注浆效果作了监测,指出该井筒通过壁后注浆避免了出水事故,提高了井筒施工的安全性。
Taking the back wall grouting technique in freezing mine of western regions of China as the example,the paper introduces the back wall grouting time,analyzes the allocation approaches of the grouting holes,monitors the grouting effect,and points out the shaft can avoid the ef-fluent accidents with the back wall grouting,so as to improve the safety of the construction.
