庙沟铁矿南帮二次扩帮方案优化研究

Study on Optimization of the Second Slope Expansion Scheme in the South Slope of Miaogou Iron Mine

针对庙沟铁矿露天转地下过渡期资源不足问题,深入分析南端帮挂帮矿资源条件及开采技术条件,从扩帮方式、范围、开拓运输、采矿方法与工艺、费用与工期等方面对南帮挂帮矿开采方案进行优化研究并实施,预计项目实施后将有利的弥补矿山过渡期资源不足。

In regard to the problem of resource shortage in Miaogou Iron Mine during the transition period from open pit to underground mining, the resource conditions and mining technology conditions of the pit~wall connected orebody at south slope are deeply analyzed, and the mining scheme of the pit~wall connected orebody at the south slope is optimized, studied and implemented from the aspects of method and scope of wall expanding, development and transportation, mining method and technology, cost and construction period, etc. It will be obtained after the project is implemented, which will make up for the resource shortage in the transition period.
