摘　　要：针对山坡露天矿渐变为凹陷露天矿,构建露天采矿场三维模型,优化开采程序和均衡剥采比,扇形过渡,由纵采转为横采;加速内排空间的释放,提升高度、缩短运距,减少征占用林地面积,构建生态屏障,降低对环境的破坏程度,促进露天矿生命周期内生态优先战略的落地。The open-pit mine constructs 3D model of open-pit mining field, optimizes the mining procedure and balances the stripping ratio, fan-shaped transition from vertical mining to horizontal mining. The mine accelerates the release of the internal dumping space, hoists height, shortens the distance, reduces the occupying forestland area, builds the ecological barrier, reduces the damage to the environment, and promotes the ecological priority strategy landing in open-pit mine life cycle.

关 键 词：均衡开采 优化内排 环境保护
