surface mining models

Applications of Queuing Theory for Open-Pit Truck/Shovel Haulage Systems

Surface mining is the most common mining method worldwide, and open pit mining accounts for more than 60% of all surface output. Haulage costs account for as much as 60% of the total operating cost for these types of mines, so it is desirable to maintain an efficient haulage system.
