摘　　要：以凤凰山银矿为背景,分析了现采矿方案存在的问题,提出了急倾斜中厚矿体在围岩不稳定的条件下,沿走向布置回采进路的无底柱分段崩落法。优化了采场的结构参数,保证了出矿进路靠近下盘布置,增加了崩落矿石的流动范围,减少了下盘残留,提高了矿石回收率。The existing problems of the mining scheme in Fenghuangshan silver mine were analysis.Sublevel caving of the arrangement of mining entrance along the run of the ore vein has been offered when the steeply inclined medium thick orebody was under the instability of the surrounding rock mass.The structure parameter in the stope was optimized.The entrance of ore removal is enabled to be close to footwall arrangement,and the scope of the flow of ore is made greater.Footwall residual amount is reduced and the ore recovery is raised.
