摘要
以某铁矿爆破开采的炸药单耗预测为例,介绍了运用Kuznetsov和Rosin-Rammler数学模型在给定大块率情况下,所需炸药单耗的预测方法及其计算过程。根据使用经验,对在露天矿爆破开采中使用Kuznetsov和Rosin-Rammler数学模型进行爆破参数优化等提出了评价和建议。
With the forecast practice of the unit explosive consumption for blasting in an open-pit iron mine, the fore- cast method and calculation method by Kuznetsov and Rosin-Rammler mathematical model at a given boulder yield are pres- ented. Evaluation and suggestions are made on the optimization of blasting parameters of open-pit blasting by the said model based on the practical experience.
