摘要
针对金山店余华寺深部开采方案的选择,采用净现值与内部收益率综合分析法,对无底柱崩落法和充填法分别进行技术、经济效益的动态评价,得出充填法更优。在该矿现有条件下,充填法不仅技术可行,还能减轻对环境的影响,提高资源利用率,给矿山带来更高的净收益,实现矿山的绿色、安全、经济开采。
The comprehensive analysis of NPV and IRR is made in the selection of deep mining plans for Yuhuasi Section in Jins handian Iron Mine to conduct the dynamic evaluation of economic benefits for non pillar sublevd caving and filling method separate ly. The results show that the filling method is better in economic benefits. The filling method is technically feasible, can mitigate the environmental impacts, improve the utilization rate of natural resources and bring higher net benefits to conduct green, safe and economic mining.
