Discussion – Large Dozer Stripping Case Studies – Mining Engineering, Vol. 45, No. 9, September 1993, pp. 1185-1189 – Hrebar, M. J.

This is a response to M. J. Hrebar's paper, which tracks in detail the highly productive stripping capabilities of modern large bulldozers at two separate installations. It proves the old adage "economies of scale" and quantifies the advantage of being able to move large loads of dirt over comparatively short haul distances by sliding rather than carrying the load. This discussion examines whether a bulldozer is the most efficient way of using this geotechnical principle.
