An auger for tunnelling or mining coal or other minerals, said auger comprising: a. a hollow cylindrical auger head, b. a first tubular drive shaft connected to the rear end of said auger head to rotatably drive same, c. a plurality of cutting bits mounted at the forward end of said auger head for rotation therewith, and.

7.3.4: Highwall Mining. Highwall mining is very similar to auger mining in its concept, where the entry into the coal seam in made at the highwall of the ultimate pit limit. The difference lies in the use of a more sophisticated machine, known as a highwall miner. The highwall miner shares some common elements with a continuous mining machine.
