浅谈特大型露天矿境界优化及分期开采

A Tentative Study on the Pit Optimization and Staged Mining of Oversize Open Pit Mine

根据某特大型露天矿的地形、矿体赋存、品位变化等特征以及开采规模,研究该露天矿境界优化、分期开采的方法,以求最佳开采顺序和最大经济效益。

Based on the topography, orebody occurrence and variation in grade of oversize open pit mines and mining capacity, pit optimization and mining by stages are studied so that optimal mining sequence and economic benefit can be achieved.
