The shovel-dumper system is a prevalent material transportation system extensively utilized in open-pit mines across the globe. It typically consists of multiple transportation dumpers and shovel-loading equipment working in tandem to transport materials efficiently (Zhang Y., 2022). Indeed, the transportation system cost in open-pit
So, to reduce the cost of operation the dumpers must be allocated and dispatched efficiently. The haulage systems should be designed in such a manner that the availability, performance and utilization of the dumper and shovel are maximized, which ultimately yield in high production and reduction of operating cost.
In a certain case, a dumper overtook a water-sprinkling truck even though over- taking is banned on the haul roads. The DCMP breaks down often. In some cases, dumpers wait for a few minutes before they are finally instructed to dump near the DCMP and move along. This wait time can be reduced if DCMP informs the dumpers on time.

Operating costs include operator's wages, cost of fuel, lubricants and other consumables, cost of transportation, erection, dismantling, insurance charges, etc. All these costs are to be
mining project. The cost per ton of material handled/won includes the owning cost of equipment, which includes the depreciation, interest on capital etc., and the operating cost, which includes the cost on maintenance, energy and the labor[1]. Useful life of the equipment It is established that most repairable HEMM exhibit a "bath
capital and operating cost associated with dumpers always contribute towards heavy capital and inventory expenditure for surface mine operation [6]. Optimization of fleet size with a techno-economic evaluation on dumpers in respect to capacity of loading equipment has a significant impact on cost of production.
calculated as 0.15 kWh/cum whereas the best operating SDC values of dump trucks operating in same mine is 0.47 l/cu.m. The overall SEC of loading and hauling operations calculated for the same opencast mine is 17.76 MJ/Cu.m and SEC of total operation in mine is 27.2 MJ/Cu.m. The best practices opencast mine
