摘要： A mining machine including a frame, a cutting head moveably coupled to the frame and pivotable about an axis that is substantially perpendicular to a first mine surface, and a first actuator for stabilizing the frame relative to the first mine surface. The first actuator is coupled to the frame and includes a first end extendable in a first direction to engage the first mine surface. The extension of the first actuator is automatically controlled based on measurements of at least one indicator of the force between the first actuator and the first mine surface.

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： A cutting apparatus suitable for creating tunnels and subterranean roadways includes independently pivoting supports that each carry a respective independently pivoting arm and a rotatable cutting head. Each cutting head via the supports and arms, is configured to slew laterally outward in a sideways direction and to pivot in a vertical upward and downward direction. The supports and arms are mounted on a linear moving sled carried by a main frame.

摘要： A method of monitoring a longwall shearing mining machine in a longwall mining system, wherein the shearing mining machine includes a shearer having a first cutter drum and a second cutter drum, includes receiving, by a processor, shearer position data over a shear cycle. The horizon profile data includes information regarding at least one of the group comprising of a position and angle of the shearer, a position of the first cutter drum, and a position of the second cutter drum. The method also includes analyzing the shearer position data, by the processor, to determine whether a position failure occurred during the shear cycle based on whether the computed horizon profile data was within normal operational parameters during the shear cycle, and generating an alert upon determining that the position failure occurred during the shear cycle.

摘要： The invention relates to a pick (10, 11), in particular a round-shank pick, for use on a cutting roller, comprising a pick head (20) and a pick shank (40) for holding the pick in a pick holder (50), wherein the pick head of the pick has at least one cutting region (20.3). Provision is made here for a planar and/or recessed ejection region (20.4) to be arranged in a central region of the pick head so as to directly or indirectly adjoin the cutting region. The pick has an optimized conveying function for the material to be removed.
