摘要
针对冶金露天矿山在产量统计工作中一般以验收采剥带内地质矿(岩)量替代采(剥)矿(岩)量而人为地优化损失与贫化指标的问题,提出改进意见。
Based on the statistical work of ore output in metal open-pit mines,generally ,the mining-stripping ore (rock) output in the mining-stripping bands are replaced with the minable geological ore (rock) reserve with the artificial optimum ore loss and ore dilution indices. The improvement opinions of this problem are put forward.
