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 view of the fact that the Shifengshan Copper Mine is depleted in resources, low in grade and high in operating cost, the research on the mining technology for inclined medium and thick ore bodies has been carried out. Experimental results show that through the use of bottomed and column ladder mining program, the ore depletion rate dropped from 26.7% to 6.2%, saving 1.442 million yuan for the same type of mine in the stope structure optimization provides technical support to the mine The sustainable development is of great significance.
