Abstract

The open cast mining apparatus comprises two sets of running gear between which a cutting drum is provided on a chassis. The conveyor tract is formed by an axial discharge conveyor inside the cutting drum, a vertical worm conveyor and a conveyor in the discharge jib or in the connecting bridge. The latter is supported on a loading carriage travelling parallel to a working face belt. The cutting drum is so designed that the mining machine can excavate and pick up material to be conveyed in both travelling directions.
