摘　　要：针对盘龙铅锌矿前期地下开采过程中遗留的空区与矿柱问题,确定采用尾砂胶结充填处理采空区,同时根据矿柱的具体情况分别选用点柱式上向水平分层充填采矿法、上向水平分层进路充填采矿法、上向水平分层充填采矿法进行回采,三种方案的采场生产能力为70-100t/d,采矿损失率为10%-15%,贫化率为7.5%-10.5%。结果表明：矿山采用的充填采矿方案是适用的,且应用效果良好。There were some problems caused by the left goafs and pillars during the previous mining in Panlong lead-zinc deposit.To solve these problems,cemented filling with tailing was applied to deal with goafs.Meanwhile,according to the detailed conditions,pillars were respectively mined by point-pillar upward horizontal cut and fill stoping method,upward horizontal sliced drift cut and fill mining method and upward horizontal cut and fill stoping method.The production capacity of the stope under these three methods was among 70-100t/d,the loss rate was among 10% -15%,and the dilution rate was 7.5%-10.5%.The results indicated that filling mining method was feasible to this mine,with preferable application.
