| 摘 要： | 针对唐口煤矿地质条件复杂、涌水量较大等特点,提出了采用单液水泥浆和黏土水泥浆等2种浆液对主井井筒进行地面预注浆。注浆工程竣工后,开挖施工井筒,对整个注浆段剩余涌水量进行实测统计发现:井筒剩余涌水量不足2m3/h,平均堵水率为96.9%,注浆堵水效果显著。

| Abstract: | According to the complicated geological conditions and high mine water inrush and other features of Tangkou Mine,a single cement grout and a cement and clay grout were provided for the surface pre-grouting of the mine main shaft.When the grouting operation completed,the excavation and sinking operation was conducted for the mine shaft.A site measurement on the residual water inrush in the full grouted section was conducted and it was found that the residual water value in the mine shaft was not over 2 m3/h ... |
