Abstract
A mobile mining machine includes a movable machine base frame having a boom, a swinging device for swinging the boom, and a tilting device for tilting the boom. At least one tool drum is coupled to the boom for rotation about a drum axis and rotatable tool carriers are arranged on a circumference of the tool drum. The boom has a supporting arm, on which the tool drum is mounted, and a separate swinging base, which is swingable about a swing axis in relation to the machine base frame by the swinging device. The supporting arm and the swinging base are connected to one another by a system of guide bars, by way of which a setting angle of the drum axis in relation to the swing axis is adjustable.
