平果铝土矿复垦研究与设计

Study and design of reclamation in Pingguo bauxite mine

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,可供复垦设计与施工技术人员参考。

According to the conditions of Natang ore block in the first phase of the project in Pingguo bauxite mine, that are samll overburden amount, large range and think clay bottom, small range karst bottom, developed solution cave and dentation stone, three plans of reclamation are put out. The selected plan is level filling and dry reclamation. This plan has high reclamation rate, simple technology, short cycle, low cost and good profit. It is a reference for other reclamation design and construction.
