Ore Handling
Used to drill large diameter holes for orepasses, raises, and ventilation shafts. A 6" pilot hole is first drilled between 2 points. A shaft is extended through the hole and a large diameter bit is attached. The machine lifts the bit creating a high force against the face. The bit cuts the rock as it is rotated.
