摘　　要：东升庙铅锌矿对回收矿柱资源开展了大量的工作,通过多年的实践逐渐形成了一套较为完整的资源回收和采空区治理体系。针对11-1号矿体02间柱一侧为胶结充填一侧为空区的状态,采用强制崩落上部围岩与采掘废石联合充填空区、在覆岩下逐排后退式回收方案,成功回收矿产资源20.98万t,取得了间柱综合回收率75.62%,贫化率23.48%的较好指标。Dongshengmiao lead-zinc mine has carried out a lot of work on the recovery of pillar resources,and gradually formed a relatively complete resource recovery and goaf management system through years of practice.According to the condition of one side of No.11-1 orebody 02 intercolumn is cemented and the other side is goaf,the recovery scheme of forced caving of upper surrounding rock and mining waste rock combined with filling goaf and backward recovery row by row under overburden was adopted,which successfully recovered 209,800 tons of mineral resources,made a good index of the comprehensive recovery rate of inter column 75.62%,dilution rate 23.48%.
