摘　　要：目前中国铁矿资源85%以上为露天开采,国内大部分露天矿山企业面临露天转地下开采的问题。介绍了铁矿露天转地下开采工程特点及无底柱分段崩落法,分析了无底柱分段崩落法的最佳工艺参数,基于铁矿露天转地下开采工程实际,探讨了无底柱分段崩落法在铁矿开采过渡期的应用,为铁矿露天转地下开采平稳过渡提供技术保障。At present,more than 85%of China's iron ore resources are open-pit mining,and most domestic open-pit mining companies are facing the problem of converting open-pit mining to underground mining.This paper introduced the characteristics of the iron ore open-pit to underground mining project and the pillarless sublevel caving method,analyzed the optimal process parameters of the pillarless sublevel caving method,and discussed the application of pillarless sublevel caving method in the transition period of iron ore mining,which can provide technical support for the smooth transition of iron ore from open-pit mining to underground mining.
