<p>The invention provides for an advance-working or mining machine for mining rock, with disc or roller tools operating according to the undercut principle, which are mounted for rotation on a swivelling jib arm of the machine, with a head carrying the tools, the axis of rotation of which extends essentially in the direction of the jib arm axis, wherein the head carrying the tools on the machine frame is mounted for swivelling around an axis that crosses the axis of the jib arm and in the advance-working direction extends in front of the swivelling axis of the jib arm arranged transversely to the advance-working direction, and wherein a swivel bearing of the jib arm is arranged on a carriage that can be moved in the longitudinal direction of the machine frame. The machine frame can be braced between a floor and a root by a plurality of props, wherein the props are arranged on both sides of the longitudinal centre plane of the machine frame. On the carriage in the area of the swivelling axis of a swivel mechanism at least one prop is arranged which can be set against the roof and the floor, wherein swivel cylinders for swivelling the jib arm extend V-shaped and, seen from above, are arranged inside the support props.</p> |
