ABSTRACT:
An auger support assembly for use with an augering system for mining which bores a pair of side-by-side holes through a coal seam using dual side-by-side augers. Each auger includes a drilling section which is followed by a series of auger flights for conveying the bored coal back out of the respective hole. The augers are connected together in axially aligned pairs and are supported by the auger support assembly. The auger support assembly includes a pair of bearing housings that are disposed on drive shafts which extend outwardly from the first ends of a first pair of parallel augers and are received within the second ends of a second pair of parallel augers. The bearing housings are connected to each other by a tie bar. A single support leg extends downwardly from approximately the mid-section of the tie bar to engage the ground ledge that is formed between the counter rotating augers.
