中条山有色金属公司铜矿峪矿690中段4矿体主层设计选用3m3电动铲运机出矿,因下落块度偏大(约1～2m),直接铲装对出矿、运输和选矿都不利,且过大的矿石铲运机无法铲装,溜井振机也无法通过。传统的二次破碎采用爆破方式,如在本系统采用爆破将产生以下不利因素:(1)爆破材料消耗过高
Zhongtianshan Nonferrous Metal Company Copper Mine Valley Mine 690 Middle 4 orebody main layer design 3m3 electric scraper used to mine, due to the larger size of the drop (about 1 ~ 2m), direct shoveling out of the mine, transport and beneficiation Are unfavorable, and too large ore scraper can not shovel loading, slipper vibration machine can not pass. The traditional secondary crushing blasting, such as blasting in this system will have the following unfavorable factors: (1) blasting material consumption is too high
