昆阳磷矿系一大型缓倾斜山坡露天矿山。一九六五年开始建矿,原设计能力为160万吨/年,平均剥采比为1:1.99,全年岩矿总量为866.41万吨。排土场距离为1.4～2.2公里左右,矿体倾向为北南方向,现在开采的一、二采区排土场位置均设在矿区的东北角方向。随着开采深度的延深,剥离运输距离越来越远,加上其它因素,至使矿石成本逐年增高,经济效益降低。为此,本文就本
Kunyang Phosphorus Mine is a large, gently inclined sloped open pit mine. The construction started in 1965 with the original design capacity of 1.6 million tons per year and an average stripping ratio of 1: 1.99. The total volume of rock and ore resources in the year was 8.6641 million tons. Dump site distance of 1.4 to 2.2 km, the ore body tends to be north-south direction, now mining the first and second mining areas are located in the northeast corner of mining area. With the deepening of mining depth, stripping away from the transport more and more far, coupled with other factors, to make the cost of ore increased year by year, reducing economic efficiency. To this end, this article on this
