摘要
针对低品位缓倾斜薄矿脉开采矿石损失大、贫化率高、回采经济效益差的问题,提出了矿岩分采分出铲运机出矿的技术方法,对试验采场布置和回采工艺进行了探讨。结果表明,这一新的技术方法有利于提高矿石回收率,降低贫化,提高回采效率。
According to the low grade of gently inclined thin vein mining ore loss,high dilution in mining,poor economic problems put forward the mining technique which respectively,mining ore and rock,the test stope layout and mining technology are discussed.The results show that,this new method can improve the recovery rate of ore,reduce the dilution and enhance the recovery efficiency.
