ABSTRACT:
In an open-pit mine with several excavation sites and a fleet of trucks carrying ore from loading stations near these sites to a number of unloading stations, data concerning production schedules are manually fed into a programmer together with information on the yield of each loading station as determined by local ore analyzers, on the identity and location of vehicles as ascertained by roadside monitoring units, and on the loading and unloading rates as detected by sensing elements at the various stations. The programmer classifies the several loading stations in two groups, i.e. one group with a below-average content and another group with an above-average content of valuable material (ore) in the excavated mass, and determines the number of vehicles to be routed to the stations of either group on the basis of the ratios of unloaded ore and overburden to their respective production quotas, taking into account the number of vehicles waiting at the loading stations and the travel times of available vehicles to their assigned stations as displayed by a traffic simulator. Routing instructions are supplied to the drivers of empty vehicles by address boards located on the approaches to road junctions giving access to the various loading stations.
