    2018-3-4 · Rotary drilling is a versatile method for blast hole drilling. It is the dominant method for holes larger than 203 mm (8”) diameter. In smaller holes, it is most common in softer rock formations. The drilling principle is to use a high pull down force (weight-on-bit), rotate the drill bit, and blow the rock cuttings to the surface with compressed air. Hardrock drills typically use the Rotary method to drill …
