Air Rock Drilling

Compressed air carries cuttings to the surface. Direct rotary air and down-the-hole hammer systems are common approaches.

A weighted drilling string repeatedly rises and falls to break material. Cuttings are removed from the bore between drilling cycles.

A rotating bit cuts the formation while circulating fluid brings cuttings to the surface.
