摘　　要：探讨了蒙库铁矿938 m以下矿体开采阶段高度划分的问题,其中影响阶段高度划分的关键因素,包括矿体赋存条件、开拓方案、采矿方法、开采规模、天溜井施工工艺等,并提出了三种不同的阶段高度划分方案。通过对这些方案的投资、技术经济和优缺点的比较,确定一个既技术可行又经济合理的阶段高度划分方案,以适应矿山生产规模400万t/a的需求。The problem of level height division of Mengku iron ore body below 938 m is discussed.The key factors affecting the level division include the ore body occurrence conditions,development plan,mining method,mining scale,and ore pass and raise construction technologies.Three different level division schemes are proposed.By comparing the investment,techno-economics,advantages and disadvantages of these schemes,a technically feasible and economically reasonable level division scheme is determined to meet the needs of the mine production scale of 4 million t/a.
