摘　　要：过渡期的产量衔接是矿山露天转地下开采关键技术难题之一。以峨口铁矿为研究对象,在综合分析了矿山资源、露天生产现状、露天采剥进度计划以及地下开采分区的基础上,提出了地下产能配合露天产能生产衔接和露天产能配合地下产能生产衔接两大过渡方案,并将其应用到矿山得出了最符合实际情况的产能平稳过渡方案。The output connection in transitional period was one of the key technical difficulties during the transition from open-pit to underground mining.Taking E＇kou Iron Mine as a case,two proposals for the smooth transition were given based on the comprehensive analysis of the mine resources,opencast production status,opencast stripping schedule and underground mining district.One was the underground output production with the aid of open-pit production,and the other was open-pit production with the aid of underground production.These two proposals were applied to the mine to obtain the most realistic programs for smooth transition.
