Displacement auger drilling uses a specialized auger to displace the soil laterally, creating a hole without removing any material. Displacement auger drilling is necessary only when the soil's surrounding integrity needs maintenance, such as installing heat pump systems in the ground. Sonic Drilling
Auger mining uses large-diameter drills mounted on mobile equipment to bore into a coal seam. Holes are horizontally drilled at regular intervals to depths of as much as 1,000 feet. As the cutting head of the auger bites into the coalface, the cut coal is carried out by the screw portion of the bit. Once the hole is mined to its required depth ...
