for mining equipments due to following reasons: • Mining is a serial operation of drilling-blasting, loading, hauling and dumping. Therefore, the production of equipments used in each step depends on the production of previous equipment. That means utilization of each equipment affects the others. • The capacity of mining equipment is huge.
