摘　　要：针对北阿尔登—托普坎铅锌矿8202-3采场回采难题,经比较分析研究决定采用水平中深孔阶段崩矿嗣后充填法回收该部分矿体。详细介绍了水平中深孔阶段崩矿嗣后充填法回采工艺。现场工业试验表明,该采矿方法回采作业安全高效,取得了良好的技术经济指标,采场综合生产能力250t/d,矿石损失率10%,矿石贫化率12%。研究成果对类似矿体的安全高效回采具有一定的指导意义。To recovery the rich orebody of 8202-3 stope in North Arden-topcan Pb-Zn Mine safely and efficiently,the horizontal middle and deep-hole pillar bench caving method with backfilling is selected out and its operation process are introduced.According to the engineering practice,the stope production capacity is 250t/d,the ore loss ratio is 10% and the ore dilution ratio is 12%.By the way,the successful practice also has a certain reference and guidance significance to other similar condition mines.
