        skos:definition  "Mechanically-driven auger drilling, typically used in hard ground or for holes that are too wide or deep for hand auger drilling. Auger drilling is done with a helical screw which is driven into the ground with rotation; the earth is lifted up the borehole by the blade of the screw. Small power augers can be portable or mounted on the back of a utility truck, with larger auger rigs used for construction, like sinking piles for bridge foundations or mine shafts."@en ;
