Keeping the distance between the loader and the truck as short as possible boosts productivity. The shorter the distance the loader travels to the truck, the faster the operator can return to the pile for the next load. As the pile reduces, the position of the haul truck must be adjusted to …used as haul ways, the selection of effective loading and hauling machines becomes an important factor to consider if a mine wishes to optimize its haulage system. This paper presents a simulation study of the truck-loader haulage system with a view to optimizing the mine's fleet.Economic Overhaul Distance = Cost of Borrow / Cost of Overhaul Freehaul: Distance with which there is a fixed price for excavating, hauling, and dumping regardless of the distance moved. Mass Haul Diagram: It is a diagram provides a suitable means for studying haul ….

Conversely, some loader capacities exceed the capacity of the truck. If we are determined to nd the best truck and loader set, then we must model the problem such that we select the truck and loader types simultaneously. Mining trucks, also called haul trucks or o -road trucks, haul the ore or waste material from the loader to a dumpsite.
