摘要
查清造成矿井水文地质灾害原因,采用地面钻孔注浆充填、井下砌拱、混凝土辅底、埋管注浆帷幕方法,对广西大新锰矿胶带斜井矿井井筒揭露的岩溶溶洞、裂隙构造水体全面帷幕封闭,在巷道周围形成帷幕隔水体,切断水路,达到防治水害目的。
This paper discusses about the investigation of mines in hydrogeological disasters caused by the reason foundation,including the surface drilling grouting in filling,underground masonry arch,concrete and auxiliary bottom,buried pipe curtain of grouting method in mine shaft.The author exposes something of the karst cave,fissure water curtain closed around the roadway to form a rigid by closing the curtain across the water leakage water to cut off the waterway with the prevention and control of water disasters in the end.
