凤凰山铜矿试验成功的大孔径深孔采矿、振动机组出矿运矿连续开采法,具有回采强度高、出矿能力大、成本低、作业安全等优点。试验采场采用的无二次破碎水平底部结构,大大减小了矿房损失贫化率,提高了出矿效率;采用间隔装药孔内同段孔间微差侧向挤压崩矿爆破方案,达到了理想的崩矿效果。
The successful experiment of large-aperture deep-hole mining and vibrating unit in Fenghuangshan Copper Mine have the advantages of high recovery mining strength, large mining capacity, low cost and operational safety. No secondary crushing horizontal bottom structure adopted in the test stope can greatly reduce the depletion rate of mine houses and improve the efficiency of ore drawing; , Reached the ideal collapse effect.
