Rolling resistance analysis in open pit mining hauling
In open pit mining hauling, the influence analysis of the geometric and operational parameters of the haul roads is still not very expressive. Thus, in this study, mathematical models are developed for productivity and transport costs, including a greater diversity ofhaul parameters. Geometric parameters such as the thoroughfare slope and curvature radius and operational parameters such as deformation and pressure, truck gross mass and speeds are found to be related in the calculation of rolling resistance and total resistance to movement, thus enabling general optimization models.
