  • Optimum Dump Slope Design of a Lumpy Chromite Ore Mine

    Shovel dumper combination is used for overburden removal as well as ore mining. A geotechnical study was carried out to determine the optimum dump height and its overall slope angle. It was also aimed to know the interplay and effect of the input parameters of slope design on the factor of safety, which tells the importance of theOptimization of shovel-truck system for T surface mining,idle time of the shovel and the cost of providing extra trucks. The solution yields the optimum number of trucks of any given capacity that can be assigned to a shovel. For an operation involving single shovel and N trucks, the total hourly cost is C1 + C2 N, where C1 is the cost per unit time of shovel and C2 is the cost per unit time of a
