ABSTRACT:
A full face miner including a simplified conveying arrangement and designed for easy maneuverability into and out of mine sites. A plow operatively mounted to and longitudinally movable with each of a pair of rotatable cutting heads of the miner provide for the conveyance of cut coal to a middle conveying portion for ultimate transport away from the mine site. The mounting mechanism for the cutting heads is designed so that at least the end portions thereof are movable from a position generally parallel to the mine face to a position generally perpendicular to the mine face and extending in front of and in line with the central conveying means, for ease of withdrawal from the mining area. A motive power source, such as a powered crawler or powered wheels, is provided which is movable into operative engagement with the ground to transport the miner to and from the mining site when in a collapsed position.
