7.3.3: Auger Mining. Earlier in this lesson, you saw the highwall that remains after the ultimate pit limit is reached in a contour mining operation. At that time, I pointed out the possibility of recovering the coal under the highwall, by either developing an underground mine or highwall mining. The former is rarely economically feasible today ...
Auger boring is a non-displacement technique which enables installation without ground heave. The system is relatively simple to operate with an experienced crew and is relatively non-intrusive to the environment. Auger Boring is a technique, usually non- or limited steer, for the bored installation of a casing pipe into the ground.
