The use of conveyors in the mining and mineral processing industry are one of the most effective ways of transporting bulk materials (e.g. overburden, wood chips) continuously over long distances. In order to optimize relevant processes (e.g. boiler operation, the amount of fibers that are fed into the tank) the amount of material transported by conveyors needs to be monitored and controlled.

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.
