针对凡口铅锌矿“盘区上向分层充填采矿法”采场生产能力不大的现实,通过优化设备配套、落矿方式、爆破参数和采场高度等采矿工艺,形成了“盘区机械化采矿新工艺”。这样,不仅提高了回采强度,也提高了矿山综合效益。 Aiming at the fact that the production capacity of stope is not large, the mining technology of “lead-zinc-zinc ores in the plate area” to “stratified charge-filling method” has been adopted. By optimizing mining equipment, mining methods, blasting parameters and stope height, “Panel mechanized mining new technology ”. In this way, not only improve the recovery strength, but also improve the overall efficiency of mines.
