摘要
针对胡家河煤矿主井井筒穿过的岩层情况和水文地质条件,确定采用一次全深冻结防治水方法,通过优化中深孔爆破参数、机械配套、施工辅助系统等,实现了快速施工,井筒掘砌连续3个月达到120m,为我国冻结法防治水井筒快速施工积累了经验。
According to the actual conditions of surrounding rock and geohydrologic shaft in Hu Jia - River Mine, the deep freezing construction scheme in one time was finally used. The aim of rapid construction was fulfilled though optimizing parameters of deep- hole blasting, assorted mechanization, support systems and so on. The length of shaft reached 120m by sequential advancing and building in only three months.
