<p>The invention relates to a mobile mining machine, in particular for driving and advancing tunnels for example in hard rock, with a movable machine base frame 1, with (at least) one tool drum 50, which can be rotated about a drum axis T and has stripping tools 54 arranged on the circumference of the tool drum, with a rotary drive for the tool drum 50, with a boom device 20, with a swinging device for swinging the boom device 20, and with a tilting device 40 for tilting the boom device 20. In order to be able to bring about the driving and advancing with a high extraction rate and low tool wear, the boom device 20 has a supporting arm 22, on which the tool drum 50 is mounted, and a separate swinging base 21, the supporting arm 22 and the swinging base 21 being connected to one another by means of a system of guide bars 23, preferably formed as a trapezoidal four-bar linkage system, by way of which the setting angle of the drum axis T in relation to the swing axis S can be adjusted.</p> |
