This survey is a comprehensive, quick reference guide for surface mine operators. It details what rotary blasthole drill rigs are available around the world. The survey covers over 60 drills, each with a pulldown of about 125 kilonewtons (27,500 pounds). They are manufactured by companies in eight different countries. Drill rigs continue to grow in size and power as larger diameter blastholes increase drilling economy. With a range of units costing from approximately $200,000 to over $1,000,000 each, careful selection based on the requirements of specific mines is essential.
