摘要
露天矿分期开采工艺先进，效益显著。以海南铁矿为例，从经济评价的角度对其分期与全境界开采方案的经济效果做了对比分析。结果表明分期开采方案明显优于全境界开采方案。
Plase-mining of an open-pit mine is characterized by advanced technology and dramatically economic efficiency. Taking Hainan Iron Mine for example, the authors have made a comparision between its plase-mining and overall mining schemes. The results show that the former has an advantage over the latter in technical and economic efficiency.
