An open-cut mining cutter (1) composed of a track-laying vehicle (2) with a superstructure and substructure (5, 6), an extraction element (7) and a conveyor means (21-23) connected thereto for the extracted materials. The support or driving regions (12) of the extraction element, which can be raised and lowered, and also be tilted and pivoted, are cut out by cutting cylinders (8, 9) arranged in these regions and extending at an angle in relation to the vertical. The cutting cylinders, which are arranged in pairs and can be driven in opposite directions, may also form the extraction element. |
