Loading and hauling materials, typically referred to as a haulage system, are critical in any mining activity. In a surface mining operation, one of the prominent types of such systems consists of shovels and trucks as loading and hauling equipment. Material movement accounts for 35% to 60% of operation cost in surface mining [1,2]. …

various elements. The loading and hauling approach in open-pit mining has been considered the main important part of the mining sector for a long time due to its expansion in size, scale and modernization of machinery. In open-pit mining, the Shovel-Truck (ST) is the widespread method for the loading and hauling stage [13]-[15].
