|Some recent and current research and development projects relating to strip type open cut coal mining are reviewed. The projects include a dragline-hopper-truck mining system, an overburden slusher system, improvement of dragline operations, continuous excavation and conveying of overburden materials, and a steep angle coal conveying system. Most of these projects offer prospects for reducing costs in deep strip mining operations, but only the overburden slusher project has the potential for large cost reductions. A project on highwall mining of coal has demonstrated that this coal mining system is viable and capable of achieving high productivity rates. Production highwall mining operations are now starting to become established in Australia.|
