Abstract
Methods, systems, and computer-readable media containing instructions for controlling a miner. One system includes a cutter head, a left tram system, a right tram system, and a cutter head controller. The cutter head includes a plurality of bits and a plurality of sections defining at least one recess. The left and right tram systems are configured to move the miner, and the cutter head controller is configured to vary a current speed of at least one of the left tram system and the right tram system to cause the cutter head to alternate back and forth to bring the plurality of bits into engagement with material accumulating within the least one recess.
