The highwall miner can advance 1200' under the highwall compared to a typical 300' for an auger. Recovery rates improve from roughly 30% for an auger to near 50% for a highwall miner. The highwall miner can adapt more easily to varying seam thickness or other changes under the highwall. Its production rate can be much higher than an auger ...

Auger Mining
Auger mining is a method for recovering coal by boring into a coal seam at the base of strata exposed by excavation. Normally one of the lowest-cost techniques of mining, it is limited to horizontal or slightly pitched seams that have been exposed by geologic erosion. Augering is usually associated with contour strip-mining, recovering coal for ...
