Abstract:
Methods and systems for automatically operating a continuous mining machine. One method includes performing an automated cutting operation without requiring manual interaction using a cutterhead included in an arm pivotably coupled to a movable platform and stopping the automated cutting operation without requiring manual interaction. Stopping the cutting operation includes (i) stopping at least one motor driving the cutterhead, (ii) operating a first actuator to retract the platform from a cutting face by a predetermined distance, and (iii) operating a second actuator to swing the arm to a predetermined tramming position.
