摘要
矿石贫化率取决于放矿参数。本文除了在放矿理论上作出分析外,又进行了多步距多进路多分段放矿立体模型实验,提出当前广为应用的截止品位放矿方式必须以不贫化放矿方式取代之,特别是当回采分段数多时以不(低)贫化放矿方案为最佳。
The ore dilution rate depends on the ore drawing parameters. The paper makes both the analysis in ore drawing theory and the stereo model experiment of multi—step, multi—approach and multi—level ore drawing. It is pointed out that the cutoff grade ore drawing method which is widely used now should be replaced by non—dilution (low dilution) ore drawing method. The latter is most prefered when the mining level number are large.
