铜绿山铜铁矿二期工程设计采用露天与地下联合开采方式，以-185m标高为界,其上下部分别采用露天开采和地下开采。目前存在的主要问题包括：该矿的古矿遗址直接位于矿体上部，要求既要确保古矿遗址不受损坏，又要尽可能多回收矿产资源，因此，研究认为必须采用陡边坡露天开采和
The second phase of Tongsushan copper-iron mine project is designed to open-air and underground joint mining mode, with -185m elevation as the boundary, the upper and lower parts were used for open-pit mining and underground mining. The main existing problems include: the site of the ancient ore mines located directly above the ore body requires not only to ensure that the ancient ruins of the mine without damage, but also as much as possible the recovery of mineral resources, therefore, the study that must be used steep slope open pit mining with
