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 at least one actuator to position a platform a predetermined starting distance from the at least one coordinate, the platform supporting a cutterhead, and automatically operating the at least one actuator to advance the platform toward the cutting face and beyond the at least one coordinate by a predetermined depth-of-cut to perform a cut of the cutting face with the cutterhead.

The method of claim 1, further comprising receiving a command to initiate an automated cutting operation from a remote control unit. 3. The method of claim 1, further comprising automatically checking at least one machine interlock; andstopping automated operation of the mining machine when the at least one machine interlock has been set. 4. The method of claim 1, further comprising automatically operating at least one second actuator to position an arm at a predetermined swing starting position, the arm coupled to the platform and including the cutterhead. 5. The method of claim 4, further comprising automatically operating the at least one second actuator to swing the arm to a maximum swing angle to perform the cut of the cutting face. 6. The method of claim 1, further comprising automatically starting at least one motor to drive the cutterhead. 7.

The system of claim 13, where the control system is further configured to automatically tram the machine to a new position when the at least one actuator reaches a maximum extension. 28. The system of claim 13, wherein the control system is further configured to (i) automatically operate the at least one actuator to advance the platform toward the cutting face until the cutterhead contacts the cutting face and pressurizes the at least one actuator to a predetermined pressure value, and(ii) automatically save the at least one coordinate based on a position of the at least one actuator when the at least one actuator is pressurized to the predetermined pressure value. 29. The system of claim 13, wherein the control system is further configured to automatically stop the automated cutting operation. 30. The system of claim 13, wherein the cutterhead includes at least one oscillating disc cutter. 31. A system for automatically operating a continuous mining machine, the system comprising: a platform;an arm coupled to the platform and including a cutterhead;a first actuator configured to move the platform linearly;a second actuator configured to swing the arm horizontally;a third actuator configured to tilt the arm vertically; anda control system configured to (i) access a first coordinate of the cutting face and a second coordinate of the cutting face stored in a computer-readable medium,(ii) automatically operate the first actuator to position the platform a predetermined starting distance from the first coordinate,(iii) automatically operate the second actuator to position the arm at a predetermined cutting position,(iv) automatically operate the third actuator to position the arm based on the second coordinate,(v) automatically operate the first actuator to advance the platform toward the cutting face and beyond the first coordinate by a predetermined depth-of-cut,(vi) automatically operate the second actuator to swing the arm to a maximum swing angle to cut the cutting face with the cutterhead, and(vii) automatically update the first coordinate based on the predetermined depth-of-cut. 32.
