摘要: 根据国家对矿山开采的要求,为了提高矿山回收率,减少废物排放,某含铜磁铁矿矿山把原有空场采矿方法变更为空场嗣后充填采矿方法。变更后,矿山采矿回采率由81.2%提高到95%,盘活铁(铜)矿石25万t,有效提高了矿产资源的利用水平,同时提高了企业的经济效益,消除了空场引起的岩体环境负效应。

关键词: 嗣后充填, 采矿方法, 回采率

Abstract: According to the requirements of the mineral exploration in China,and in order to improve the recovery rate and reduce the wastes,the original open stope method is changed into the open stope method with subsequent filling. This new mining method makes the recovery rate increased from 81.2% to 95% and efficiently recovers the iron (copper) ore resources of 250 000 t. It effectively improved the utilization of mineral resources,enhances the economic efficiency for enterprises,and removes the negative effect of rock environment caused by the open stope method as well.

Key words: Stope with subsequent filling, Mining method, Recovery rate
