摘要

"BENCH MINING METHOD AND APPARATUS" A method and apparatus for bench mining employs a rotating wheel excavator with the excavator wheel positioned outwardly to one side of a tractor unit for the excavator so that the tractor unit draws the excavation wheel along a bench line or cut line between different layers of the bench mine. The cutting wheel can either be moved to opposite sides of the tractor unit or a second wheel can be positioned at the other side so that the excavator can operate in both directions of movement.
