A. S. Kaboli · D. G. Carmichael · Emission and Cost Configurations in Earthmoving Operations · pp 393-402 Introduction Earthmoving operations typically involve a fleet of trucks cycling between an excavator/loader and dump points. The analysis to obtain the optimum fleet size based on minimum cost per production (unit costs) is well-established, whereas little attention has been paid to the minimum emissions per production (unit emissions) problem. Off-road vehicles are a significant source of air pollution and produce large volumes of emissions compared to on-road vehicles such as automobiles. For example, the amount of particulate matter from a bulldozer with a 175 hp engine is nearly 500 times more than that of a new automobile (EPA, 2005). Reducing pollution from such off-road vehicles will provide decreased environmental problems. Because of the importance society places on this issue, effort is beEarthmoving; Optimal cost and emissions; Production; Quarrying; Surface mining
