The waste can also be moved with conveyors to an overburden area where it can be used for reclamation when the mine has ended it active mining time. These conveyor systems can extend for several miles / kilometers and have the capability of moving material at 10-15 miles (16-25 km) per hour.
Understanding Conveyor Systems
Conveyor Systems are mechanical devices or assemblies that transport material with minimal effort. While there are many different kinds of conveyor systems, they usually consist of a frame that supports either rollers, wheels, or a belt, upon which materials move from one place to another. They may be powered by a motor, by gravity, …
