摘　　要：采矿方法的选择受诸多因素的影响,决定着矿山生产效益,选择安全高效的采矿方法一直是矿山生产管理的重大决策内容。以重新集铁矿为例,在分析矿床开采技术条件的基础上,提出了三个合理可行的采矿方法,并通过模糊数学评价方法对采矿方法进行了优选,确定了重新集铁矿的采矿方法为大直径深孔阶段空场嗣后充填采矿法。该方案机械化程度高,生产能力大,采切比小,生产成本低,能够满足重新集铁矿的生产需求。The selection of mining methods is affected by several factors, and it determines the production benefit of a mine. Selecting a safe and efficient mining method has always been an important decision for the mine managers. Taking Zhongxinji Iron Mine as an example, this paper proposes three feasible mining methods on the basis of the analysis on orebody mining conditions, selects a better one through fuzzy mathematics optimization, and determines to adopt the sublevel open stoping cut and fill and large-diameter longhole mining method, which has a high mechanization degree, large production capacity, low mined tonnage ratio, and low production cost, so it can meet the production demand of Zhongxinji Iron Mine.
