摘　　要：厂坝铅锌矿东边坡采区为原露天矿残采区域,为了最大程度回收资源,提高回采率、降低回采成本,在充分分析采区矿体赋存及开采技术条件的基础上,采用无底柱分段崩落法为其开采方法,并对其回采工艺参数进行了详细论述。The east slope mining area of Changba lead zinc mine is the residual mining area of the original open pit mine.In order to maximize the recovery of resources,improve the recovery rate and reduce the mining cost,based on the full analysis of the ore body occurrence and mining technical conditions in the mining area,the sublevel caving method without bottom pillar is adopted as its mining method,and its mining process parameters are discussed in detail.

关 键 词：无底柱分段崩落法 回采工艺参数 地压管理
