露天采坑做尾矿库时防渗工程的施工措施

Construction Measures of Antiseepage Work When Using Open Pit as Tailing Storage

介绍大岭矿露天采矿结束后,为实现露天采坑做尾矿库并保证地下矿正常开采,对露天坑防渗加固时针对边坡脱落、坡面不平、坡度大以及施工范围大、体量大、混凝土输送距离长等具体情况,采取的边坡整形,混凝土泵送、浇筑,土工膜铺设和保护层施工等措施。

To reach the goal of using open pit as tailing storage and ensuring the normal operation of underground mine after open pit mining of Dalin mine is ended,some measures are taken in open pit reinforcement for antiseepage,which include slope shaping,concrete pumping and placing,geomembrane laying and protective layer construction,etc.to overcome adverse conditions such as falling-off slope,uneven slope face,large slope,wide construction area,large work quantity and long concrete transport distance,etc..
