| 摘 要： | 大红山铜矿属于多层缓倾斜矿体,传统小分段空场法分采存在资源回收率低、二次单耗高等缺点。采用大直径深孔侧向崩矿技术多层矿体合采,增加了开采矿体的厚度范围,提高了资源回收率,经济技术效果明显。

| Abstract: | The ore bodies in Dahongshan Copper Mine are multi-layered.The traditional subsection open-stope method has the disadvantages of low recovery and high explosive consumption.The large-diameter long-hole side caving technology is adopted to excavate multi-layer ore bodies at the same time.As the result,the recovery is raised,and both technical and economic indicators are improved remarkably. |
