Abstract
Equipment is a very important factor in ensuring the sustainability of mining production. The
amount of excess fleet will result in inflated operating expenses, while the number of fleets
that little will reduce the number of mine production. Ideal conditions in the process of
loading and transportation of materials is very difficult to achieve. However, it can be
attempted through efficiency tehadap number of major mining dump truck. One simulation
method that can be used to optimize the production of electric load - dump truck main method
is to use the production capacity and queuing theory. Simulations conducted in order to
obtain optimum number of trucks with truck queuing time the minimum and avoid waiting for
the appliance load dump truck.
Unloading tool used was Excavator Backhoe Komatsu PC 400 consist of 2 units. Dump truck
which is a truck used Hino 500 FM 320 TI totaling 12 units. Based on simulation results with
simulation approach production capacity dump truck takes 11 units while the dump truck
queues based on the theory that it takes 11 units. In actual dump truck used is 12 units.
