For a rotary drill rig, the drill bit turns under pressure to cut into the rock. As the bit turns, the rock grinds down while compressed air sends it back up the drill to the top to keep the hole and bit clean. Ideally, rotary drill bits create holes that range from 6 to 22 inches in diameter and average 30 to 60 feet deep.

For instance, a single productive rig at an open-pit iron ore mine may drill around one hundred 10–12 m blast holes per day, generating a minimum of 10,000 MWD observations with several responses per observation, including rop, tor, wob, bap, and rpm . Many major iron ore mines employ around a dozen simultaneously operating blast drills.
