摘　　要：针对狮凤山铜矿资源枯竭、品位低、经营成本高的现实,对倾斜中厚矿体开展了回采工艺研究。试验研究结果表明,通过采用有底柱分阶梯回采方案,矿石贫化率从26.7%下降到了6.2%,节约成本142.48万元,为同类矿山在采场结构优化等方面提供了技术支撑,对矿山的可持续发展意义重大。In the view of the threat of ore resources depletion, low-grade ore, high-cost mining in Shifengshan copper mine, the sublevel stoping with sill pillar for inclined and medium-thick orebody was put forward. The research re- sults showed that the ore dilution rate fell from 26.7% to 6.2 % and mining cost was saved 1,424,800 Yuan with the stoping method under the premise of ore grade remaining un- changed. The method provided a technical support for some similar mines in the optimization of stope structure, which was very significant for the sustainable development of mines.
