摘　　要：以某铁矿为工程实例,根据该矿的开采技术条件,初选了垂直深孔球状药包落矿阶段矿房法、阶段强制崩落法、无底柱分段崩落法三种初选方案。然后运用双基点决策理论选取相应的技术经济指标综合比对三种方案,确定最适合该矿的采矿方法。最后运用数值模拟方法对采场结构参数进行优化。研究结果表明,运用双基点法决策理论对采矿方法进行选择,能避免采矿方法选择的主观性,同时经现场实践证明所选取的采矿方法有效,采场结构参数合理。这些研究成果可供矿岩条件类似矿山借鉴使用。The paper takes an iron mine as engineering example,according to the mining conditions,selected VCR method,stage forced caving mining method and non-pillar sublevel caving mining method as initial selections.Then the paper uses the dual-base point method compared technology and economic indexes for the three mining methods and determines optimal mining method for this mine.Finally,numerical simulation method is used to optimize structure parameters of the stope.Using the dual-base point method to select mining method can avoid subjectivity,simultaneously it has been proved by engineering practice that the VCR mining method is effective,and the stope structure parameters are reasonable.This research can be used in other mines which have the similar mine and ore conditions.
