摘　　要：矿床开拓方案的选择对地下矿床开采具有特别重要的意义。黄麦岭磷矿将由露天开采转入到地下开采,针对如何保证矿山过渡期露天开采和地下开采作业安全的难题,提出了4种可行的竖井开拓方案。通过采用数据包络分析法,建立了以基建投入、经营成本、工程量、露天开采影响、环境保护、施工难易程度、通风条件等为主要评价指标的DEA模型,对几种开拓方案进行分析优选,最终推荐王家山竖井开拓方案为首选方案。分析结果表明数据包络分析法是一种有效的方案优选分析方法,具有广阔的应用前景。The choice of mineral deposit development program is of importance to the underground exploitation.Huangmailing phosphates mine will be transferred from open-pit to underground mining.In view of ensuring the security during the transition period from open-pit to underground mining,four shaft development viable programs were proposed.DEA model was established by using data envelopment analysis from such main evaluation indexes as capital investment,operating costs,project volume,open-pit mining impact,environmental protection,construction difficulties,ventilation condition and so on.Through using DEA model to analyze these shaft developments,Wangjiashan shaft development program was firstly recommended.The results show that the data envelopment analysis method is an effective optimization program with a broad application prospect.
