露天采矿机生产能力预测

摘要

总结和分析了6个用于计算露天采矿机生产能力的公式:技术生产能力公式,破碎比能公式以及Ge-hring、Dey&Ghose、Bilgin、Copur的经验公式,并应用7个实例分别验证了各公式的准确性,结果表明:技术生产能力公式、Dey& Ghose经验公式和经修正的Bilgin公式的预测结果较符合实际生产能力,在7个实例中,它们的相对误差平均值分别为19.4％、21.6％和24.5％.%The six empirical formulas are summarized and analyzed using to calculate the surface miner's production capacity,including the technical production formula,the crushing specific energy formtda,Gehring,Dey & Ghose,Bilgin,Copur empirical formula.Seven application instances are applied to verify their accuracy respectively.It shows that the prediction result of technical production formula,Dey & Ghose empirical formula and revised Bilgin formula are more in line with actual production capacity,and their mean relative error in seven application instances are 19.4％,21.6％ and 24.5％ respectively.
