丰山铜矿南缘矿带地下采矿巷道位于松软破碎岩层中,巷道变形、破坏严重。为解决这一问题,选用光面爆破-锚喷网支护方案。实践表明,这一方案不仅解决了丰山铜矿井下巷道支护问题,而且提高了生产的安全性,降低了矿石的贫化和损失,提高了矿山经济效益。 The underground mining roadway in the ore belt at the southern margin of Fengshan Copper Mine is located in a soft and crushed rock formation, and the roadway is deformed and damaged severely. To solve this problem, the choice of smooth blasting - anchor spray network support program. Practice shows that this solution not only solves the problem of roadway support in Fengshan Copper Mine, but also improves the safety of production, reduces the depletion and loss of ores, and improves the economic benefits of mines.
