摘要: Scrapers are commonly used in road construction, site formation, other earthmoving and surface mining operations. It is known that loading a scraper to capacity may not be best terms of unit operational cost, because the load-growth curve for nonlinear – rate decreases with load time. However, there no published research considering effect time fleet size on emissions, what corresponding optimal might be. This paper shows optimum emissions same or slightly less than cost depending type operation, while minimum higher as cost. Cost-load-time, emissions-load-time hauling characteristics, particular different equipment operations, influence conclusion. For practice purposes, it could said ...
