摘要
对现行截止品位放矿方式进行分析，指出了现行放矿方式存在的问题，这些问题造成无底柱分段崩落法放矿的矿石贫化大。论述了不贫化放矿原理和理论依据，根据实验结果分析了多分段放矿的矿石损失贫化过程。
The ore-drawing mode for currently used cut-off grade is analysed,and the serious ore dilution problem of current ore-drawing mode for sublevel caving method is pointed out in this paper, in addition, the theory of ore-drawing without dilution and its theory basis, is discussed still, and the ore dilution and loss process in the case of multi-sublevel ore-drawing is analysed according to test results.
