Patent

CA 2169048

The open cast mining apparatus comprises two sets of running gear between which a cutting drum (2) is provided on a chassis. The conveyor tract is formed by an axial discharge conveyor inside the cutting drum (2), a vertical worm conveyor (7) and a conveyor (9) in the discharge jib or in the connecting bridge(11). The latter is supported on a loading carriage travelling parallel to a working face belt. The cutting drum (2) is so designed that the mining machine can excavate and pick up material to be conveyed in both travelling directions. As compared with known solutions, the invention offers the advantage that it also permits the construction of relatively small mining machines. It permits the excavation of steep marginal slopes of the open cast pit without auxiliary machines.
