Queueing problems are often found in mining operation.
In the open-pit limestone quarry which produces 6200 tons of limestone each day by using the Caterpillar 988 (bucket capacity 4.59 m3)and 15 ton dump-trucks haulage system, queueing technique was applied to analyze the haulage operation and to decide the dump-truck capacity for the system.
Suitable number of trucks for a 1000 meter haulage distance to the crusher from the working face of the quarry was decided 3 to 4 trucks, for the reason of obtaining the lowest haulage cost per ton of limestone.
