摘　　要：针对某矿山留矿采矿法采场中部分矿石因生产原因未及时进行大量放矿致原矿长久积存采场内,部分矿石氧化结块致使无法顺利进行放矿回收的现象,结合矿山实际情况,根据存窿矿石的不同分类分别对该部分矿石的回收方法进行了阐述,提出了下盘单元格法对密实型氧化胶结矿石进行回收,取得了良好的经济效果。In response to a situation where a number of ores in a mining stope of a certain mine were not promptly released due to production reasons,leading to the long-term accumulation of ores in the stope and the oxidation and agglomeration of some ores,making it difficult to recover the ore smoothly,this study,based on the actual situation of the mine,describes the recovery methods for this part of ores based on the classification of the ores in the storage stopes.The footwall unit grid method,was proposed for the recovery of dense oxidized and cemented ores,which achieved good economic results.

关 键 词：留矿采矿法 存窿矿石 二次回采 下盘单元格法 低品位
