摘要
针对立井井筒施工时遇水的问题,通过对矿井建设过程中出现的各个井筒遇水情况进行现场调研、科学分析、合理总结,决定采用施工止浆垫技术及单液水泥浆注浆方法进行治水,实践证明注浆对井筒安全顺利通过含水层有显著效果。
According to the problem of water gushing during the construction of vertical shafts, field research, scientific analysis and rational conclusion were made for water gushing of each wellbore in the pit construction. It was decided to take technique of construction stopping slurry cushion and method of single liquid cement slurry grouting to prevent water gushing. Practice has proved that grouting has a significant effect for wellbore passing through aquifer safely.
