Rock excavation by continuous surface miner in limestone quarry

This recent study reports an investigation on the effectiveness of the cutting performance models applied to the Surface Miner Wirtgen 2200-SM operation in a limestone quarry, Palimanan, Cirebon, Indonesia. The cutting models applied in this investigation are those proposed by [Gehring, K. H. 1989. Bestimmung von Schneidleistung und Meibelverbauch. Working paper of the Voest Alpine Ges.m.b.H.Zeltweg, Austria and Gehring, K. H. 1992.

The prediction results from Gehring's model are always found higher ...
