特大型露天矿开采优化

Mining Optimization 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,研究露天矿分区、分期开采,并优化边界品位,以求最佳开采顺序和最大经济效益。

Based on the topography,ore-body occurrence and variation in grade of oversize open pit mines and the mining capacity,the sub-level mining under different stage at different district and the optimization of cut-off grade are studied so that optimal mining sequence and economic benefit can be achieved.
