合理确定矿山生产规模是露天转地下开采关键技术问题之一.以石人沟铁矿为研究对象,结合矿山具体情况提出了七个技术上可行的方案.综合考虑技术、经济和社会等因素对石人沟铁矿生产规模的影响,结合矿山实际,从现有规范、规程、标准出发,采用层次分析法与模糊综合评判理论构建了规模优化模型并进行选优,得到矿山露天转地下后地下合理规模为215万t.a-1.
It is one of the key technical problems to determine the mine production scale reasonably from the open pit to the underground mining.The paper takes Shirengou Iron Mine as the research object and puts forward seven technically feasible plans according to the specific conditions of the mine.Considering the technical, economic and social factors According to the actual conditions of the mines, starting from the existing norms, procedures and standards, the scale optimization model is constructed and optimized by the method of AHP and fuzzy comprehensive evaluation to get the underground open pit underground A reasonable size of 2.15 million ta-1.
