Mine cost reduction can be achieved through optimizing truck loading. If every truck is optimally loaded with the maximum payload this results in less truck movements and lower cost per tonne hauled. Mines use laser volume scanning technology to gain more information about their loads than can be provided by traditional weigh scales alone. 3D laser scanning enables the identification of haul-back material so that mine operators can remove it from daily shift tallies (or dig haul-back out of the truck bed when it becomes a cost prohibitive amount that reduces the maximum payload opportunity).
