Abstract The paper briefly describes the development of the Eickhoff ESA60 roadcutter which is based on the old and well used principles of the shearer loader. It is intended to show that the machine offers a viable alternative to the normal methods used for driving roadways and also for coal production. References are made to installations currently operating in Europe with applications ranging from roadway drivage to pillar recovery. The paper also looks at possible applications in Canada.
Keywords: Coal mining, Shearer loaders, Roadcutters, Roadway drivage, Pillar recovery, Mechanical cutting, Conveying, Roof supports.
