摘要
针对别斯库都克露天煤矿设计开采程序中存在的二采区开采深度过大、现阶段工作帮进入火烧区剥采比逐渐增大的问题,提出了将二采区作为后备采区的开采方案;同时提出了现状东端帮恢复为工作帮后向东推出一定距离,以降低全矿剥采比,创造内排空间,使露天矿提前实现内排的方案。采用3Dmine的境界优化功能,对东帮推出的范围进行了圈定及优化,提高了露天矿的经济效益,为国内类似的露天煤矿优化提供了参考。
According to large mining depth of the second mining area,the increasing stripping ratio problem in Biesikuduke open-pit mine mining sequence,the article presents the second mining area to be a reserve mining area,and proposes that the eastern end slope restores to work slope to promote a certain distance to reduce the stripping ratio of the whole mine,creates internal dumping space to realize the internal dumping in advance.The article adopts 3Dmine software to optimize the east mining area,which improves the economic benefits of the mine,provides reference for the optimization of similar open-pit coal mines in China.
