摘要： Methods and systems for automatically operating a continuous mining machine. One method includes accessing at least one coordinate of a cutting face stored in a computer-readable medium, automatically operating a first actuator to position a platform a predetermined clearance distance from the at least one coordinate, the platform supporting a cutterhead, and automatically operating a second actuator to position an arm at a tramming position after positioning the platform the predetermined clearance distance from the at least one coordinate, the arm coupled to the platform and including the cutterhead.

摘要： A dust scrubber for a mining shearer machine is adapted to be mounted behind the rear surface of the shearer arm, on the opposite side of the arm to the mine surface being cut, so as to extract airborne particulates. The scrubber may be mounted to the shearer via a compensation mechanism such as a double hinge and link arrangement which maintains relatively static position and/or orientation of the scrubber despite the pivoting of the shearer arm in operation.

摘要： Methods and systems for automatically operating a continuous mining machine. One method includes automatically operating at least one actuator to position a platform supporting a cutterhead at a predetermined starting position and automatically operating the at least one actuator to advance the platform toward a cutting face until the cutterhead contacts the cutting face and at least one indicator of a physical force between the cutterhead and the cutting face exceeds a predetermined value. The method also includes automatically saving at least one coordinate of the cutting face to a computer-readable medium, the at least one coordinate based on a parameter of the at least one actuator when the indicator exceeds the predetermined value.

摘要： The invention relates to a cutter head for a ground cutter machine having at least one cutter motor. Each cutter motor comprises: two hydraulic motors, each comprising a stator and a rotor and having a common axis; a single shaft extending along said common axis and having two ends; two cutter drums mounted to rotate; two transmission assemblies for drivingly connecting each end of the common shaft to one of said cutter drums; and mechanical members for constraining the rotor of each hydraulic motor directly in rotation with the transmission assembly corresponding to the cutter drum that is closer to the hydraulic motor.

摘要： A method of mining includes striking the surface of friable to brittle, essentially homogeneous mineral materials with a plurality of concave-faced cutting tools rotating about a longitudinal axis disposed substantially parallel with the surface of the mineral material. Segments of the mineral material are cleaved by the cutting tools as the tools strike the surface and then pass along a predetermined path completely through the mineral material.

摘要： A longwall mining machine comprises a rotatable cutting head having a configuration in the form of an equilateral triangle viewed along its axis of rotation and formed with a continuous auger along the outer surface of the head. Cutter bits are located on apexes of the auger. The cutting head is mounted on a boom adjacent the longwall and is geared to produce an eccentric Cardan motion to the head causing the cutter bits to follow a substantially square trajectory in a plane normal to the axis of rotation of the head. Production of coal dust is minimized by deep linear vertical and horizontal cuts extending downwardly from roof to floor. During rotation of the head, cut coal is augered outwardly from the longwall and dropped into a conveyor for removal to a collection area.
