摘　　要：露天转地下开采方案选择涉及多目标决策,层次分析法(AHP)是一种较适宜的方法。采用差值比较算法的归一化方法确定决策变量指标的标度,对无底柱分段崩落法与阶段空场连续崩落法露天转地下开采方案进行比较,综合考虑技术、经济及安全等方面的评价指标,进行层次分析决策,认为阶段空场连续崩落法更适用于露天转地下大规模采矿。Analytic Hierarchy Process（AHP）is an appropriate way of multi-objective decision analysis for open pit to underground mining plan.In this paper,the normalized difference-comparison algorithm is used to determine the variables index scale.Considering the evaluation indicators in technical,economic and safety,the plans of sublevel caving and open stoping in stage with subsequent caving process in open pit to underground mining is analyzed.And the result shows that the open stoping in stage with subsequent caving plan is more suitable for open pit to underground mining.
