摘要
根据平果铝土矿一期工程那塘矿段剥离量特少 ,粘土底板范围大且土层较厚 ,岩溶底板范围小 ,石牙、溶洞发育等具体条件提出了 3个各具特征的复垦方案 ,选定的“平填底板旱式复垦”方案 ,具有复垦率高、工艺简单、周期短、成本低等特点 ,经济效益显著。
Three different complex exploit programes were brought out based on the little peel amount bigger and ticker clay base range and small karst base,with many rock cave and solution cavities in the ore belt of Natang in pingguo,the base dry fullfill complex exploit programe were taken with simple technique,short cycle,lower cost and good economic resuit.
