摘要
深部铜矿通过应用光面爆破技术减少掘进废石产出量,采用低贫损开采技术减少采矿废石混入量,利用酸性废水处理技术对井下废水进行回收利用,井下掘进废石回填采空区,优化通风系统、提高粉尘浓度合格率等方式实现了无废开采,取得了较好的经济效益和社会效益。
In Shenbu Copper Mine, the wasteless mining was realized by using smooth blasting technique to reduce the development waste amount, by low dilution and loss mining to decrease tramp waste amount, reusing the underground water by acid wastewater treatment technique, waste rock backfill mined-out area, reducing dust density by optimizing ventilation system, and good economic and society effect were got.
