How to Calculate an Open Pit Mine Capacity

Trucks’ Waiting TimesActivity Times and Their Standard DeviationsDistribution of Shovels and TrucksThe trucks in a circuit consisting of a shovel, haulage roads for loaded and empty travel and a dumping point will due to their number and the variabilities of loading, loaded and empty travel and dumping times occasionally queue up at the shovel and the dumping point and incur waiting times. These increase with the number of trucks in the circuit and become a substantial part of the trucks’ cycle time, thus limiting the capacity of the system. During normal operation the trucks’ waiting time will some time after the sta…
