浏阳磷矿从1973年开始探索采用陡帮采剥工艺,本文着重介绍其工艺特征。一、概况浏阳磷矿是一个设计年产80万吨的中型露天矿,它座落在浏阳县东面34公里处的永和镇。全矿区走向长8公里,分为四个工区七个露天采场,其中以二工区露天采场最大,是矿山主要生产采场。该采场位于矿区中部,设计的采场参数是:长1600米,宽520米,采深130～150米,最低开采深度
Liuyang Phosphorus Mine explored the use of steep gang mining stripping process since 1973, this article focuses on its process characteristics. I. Overview Liuyang Phosphate Mine is a medium-sized opencast mine with an annual output of 800,000 tons. It is located in Yonghe Town, 34 kilometers east of Liuyang County. The entire mining area is 8 kilometers long and is divided into seven open-air stopes in four work areas. Among them, the second-work open-air stope is the largest and is the main production stope of the mine. The stope is located in the middle of the mining area. The designed stope parameters are: 1,600 meters long, 520 meters wide and 130-150 meters deep, with the lowest mining depth
