The current technology of large rock conveyors is reviewed. Based on this investigation, two large rock conveyor concepts have been developed and a test facility investigation designed and fabricated. The Bureau of Mines will test these concepts along with loading and transfer points for handling mine run rock material up to 1.5 M (4.9 Ft) in size. An evaluation of open pit mining systems using large rock conveyors documents substantial cost savings when compared with truck haulage.
