摘　　要：针对四川大梁矿业会东铅锌矿床Ⅱ号段矿岩产状复杂多变和极不稳固的开采难题,设计采用上向分层壁式袋装充填采矿法回采该类型矿体,以进路为单位组织回采,以袋装充填方式进行空区处理和地压控制,生产实践取得盘区生产能力260t/d、充填成本53.24元/t、采矿损失率10%、贫化率5%的良好技术经济指标,安全可靠地解决了该矿段复杂破碎难采的技术难题,对同类型矿体的开采具有借鉴和指导意义。Aimed at the complicated and extremely unstable mining problems at No.Ⅱorebody of Huidong Lead-zinc Mine,upwards wall-and-drift mining method with packing cemented backfilling was used to stope this ore,which organized mining with drift for the unit and managed goaf and controlled ground pressure by packing filling.Panel production capacity of 260t/d,backfilling cost of 53.24RMB/t,mining loss of 10% and mining dilution rate of 5% were obtained through production practice.The technical problems as complexity,crushing and difficult mining were successfully solved,which had guidance for mining similar orebody.
