A system and method for the drilling of ground holes by a track steer drill rig. The system and method include a drilling arrangement that permits the speed of drilling holes to be balanced against the stability of the hole thus formed. The system and method allow for the autonomous drilling of ground holes and, particularly, although not exclusively, for the purposes of exploration, mining, and/or construction. In particular, the system and method relate to the autonomous drilling of ground holes which are used for subsequent blasting.
