Abstract: In a cutting machine (1) with cutting heads or rollers (7) rotationally mounted on a pivotable cutting arm (6), including a loading ramp or a conveyor (9) extending in the direction to the mine face for receiving and removing the cut material, wherein the cutting arm (6) is mounted on a carriage (4) displaceable on guides extending in the longitudinal direction of the machine, the carriage (4) carries guide rods (12) extending in the longitudinal direction of the machine and engaging in tubular guides (13) of the machine frame (3) carrying a chassis (2).

Abstract: In a starter car for a drilling device for mining underground deposits, including a base frame (5) mounted to rotate about a vertical axis (6) and a starter pipe (7) mounted to pivot about a substantially horizontal axis (13) and provided for receiving the drilling device, the starter pipe (7) is arranged to be displaceable relative to the base frame (5) transversely to the horizontal pivot axis (13).

Abstract: In a movable conveyor belt storage installation including a belt storage means (4), conveyor belt support structures (29) following the belt storage means (4), and a movable takeover car (7) including a deflection means (43) for the conveyor belt and a takeup chute (8) for taking over excavated material, the belt storage means (4) is comprised of at least two segments (13, 20, 22, 26) which are connected with one another so as to be pivotable about an axis extending transversely to the belt running direction and passing through the plane of the floor (31), wherein at least a portion of the support structures (29) are capable of being carried along in or on the takeover car (7).

Abstract: In a full-cut heading machine including a drill head (1) for hard rock, which is rotationally mounted about an axis of rotation (6) extending in the driving direction, as well as downstream extraction tools (5) for producing a floor widened in the floor region, the downstream extraction tools (5) are arranged on the shells, and optionally end faces, of rollers (3, 4) rotationally mounted transversely to the axis of rotation (6) of the drill head (1).

Abstract: In a method for controlling the drive of a shearing or heading machine for cutting a round, as a function of manipulated variables such as the movement speed of the cantilever arm, the position of the cutting tools and/or the power consumption of the drive motors and the pressure in hydraulic actuating cylinders, a minimum and a maximum target value are determined for the movement speed of the cantilever arm, and at least two factors each having values of between 0 and 1 are calculated for the manipulated variables as a function of measurement values, the measurement values at least comprising cutting tool position data compared to set data corresponding with a set profile, motor load measurement data and cantilever arm movement speed measurement data, and the movement speed of the cantilever arm is controlled as a function of the product of the set speed and the respectively calculated factors.
