摘　　要：以黄沙坪多金属矿体为研究对象,针对原铅锌矿开采中存在的作业安全性差、生产工序复杂、生产能力低和成本高等技术问题开展研究,优化选择了分段凿岩阶段空场嗣后尾废耦合充填采矿法,经2年多的现场工业试验,该采矿法矿房生产能力一般可达400-500 t/d,采矿回收率为85.18%、贫化率为6%,采矿工班效率为40 t/工班,耙矿效率为35 t/工班,证明该方案工艺简单、劳动效率高,生产能力大,能有效避免矿柱大量损失,是一种适合于该多金属矿体的理想采矿方法。With polymetallic ore-body in Huangshaping lead-zinc mine as research object,the sublevel drilling and block open stoping with delayed waste rock and cemented tailings filling was put forward to solve such technical matters in mining as poor safety in working,complicated production processes,low production capacity and high cost.The industrial experiment more than two years showed that the productivity of single room is up to 400-500t/d,the recovery rate of ore is 85.18%,the ore dilution is 6%,the work efficiency is 40 tons per working shift,ore-scraping efficiency is 35 tons per working shift,and proved that this mining method is ideal for the mining of the polymetallic ore-body.
