REMOVAL REMOVAL REMOVAL OF REMOVAL OF OF OF CUTTINGS CUTTINGS CUTTINGS CUTTINGS � Cuttings normally don’t need to be removed with a scoop on a 25 – 30m raise, provided: • The cuttings can be washed away from the drill after every rod. • Access to the drill can be maintained so that the drill can easily be moved once the hole has been completed. � If access to the front of the drill is available with a scoop, we do like to remove the cuttings periodically.
