摘要: 为了保障采空区群内残矿资源回收的安全,采用综合指数分级法对采空区群失稳危险性进行定量评价,以地质因素、开采技术条件、残采综合因素为主要分析指数对残矿回收前、后采空区群失稳的危险程度进行评价,为残矿回收提供指导,对于类似矿山进行残矿回收具有一定的参考作用。

Abstract: In order to ensure the remnant ore resource recycle in the group of mined-out area,the composite index classfication method is adopted to do evalution on the unstability of the group of mined-out area.To be specific,the geological factors,mining technical conditions,the comprehensive factors of remnant ore resource recycle are regarded as the analysis indexs to evaluate the risk degree of unstability of the group of mined -out area before and after recycling the remnant ore resources.The evaluation results in this paper can provide guidance basis for recycling the remnant ore resource,besides that it can be taken as the reference for recycling remnant ore in similar mines.

Key words: Recycling of the remnant ore, Unstability of the group of mined-out area, Composite index analysis classification method
