Prediction of Surface Miner′s Production Capacity

Abstract

Abstract: 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 formula，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.

Key words: Surface miner, Production capacity, Crushing specific energy, Empirical formula
