露天采场残留矿回收技术

Recovering residual ore body technology in open-pit

露天开采除了按正规设计开采的主矿体外,因达不到经济剥采比的要求或者不具备机械化开采条件,还残留部分高品位边缘小矿体、薄矿体。根据残留矿体的厚度、埋藏深度及周边开采条件的不同,选用相应的回采技术,在确保安全环保的前提下,最大限度地回收矿石资源,取得了一定的经济效益和社会效益。

Because the stripping ratio can not meet the economic demand or the ore body can not meet the machanical mining conditions, some small and thin ore body with high grade had not been mined out in open-pit mining. According to the height, buried depth and surrounding mining condition of residual ore body, relevant recovery technology was used to recover the ore body maximally under ensuring safety production and protective envirnoment, and good economic and social benefit were obtained.
