发明名称 LOW PROFILE COAL MINING APPARATUS
摘要 Apparatus for mining shallow seams of coal or the like employs a combination of parts resulting in a low profile of the machine and which may be operated without requiring an operator to accompany the machine to the mine face. The mining augers are remotely controlled and may be adjusted to provide for mining of seams which are thicker than the minimum profile height of the machine. The augers are mounted on a carriage which travels along guides on a base plate which can be shifted toward or from the mine face by remote control, and the superstructure mounted on the carriage reaches a height no greater than the diameter of the augers.
