<p>An auger flight support (20) for use with an augering systems (23) for mining which bores a pair of side-by-side holes through the coal seam (38) using respective augers (29). Each auger (29) includes a drilling section (32), which is followed by a series of auger flights (53) for conveying the bored coal back out of the respective hole. The auger flight support (20) includes a pair of thrust bearings (164) and housing assemblies (80) which are tied together and each supported by a respective leg (125), which lowers the friction between the auger flight and the bottom of the bore.</p> |
