In-The-Hole Longhole Drill Rigs
Sandvik in-the-hole (ITH) longhole drills are capable of drilling ø89-216 mm holes up to 100 meters in length using 3” to 8” ITH hammers in mechanized and automated underground mining operations. The target of these Sandvik longhole drills is to maximize ore recovery and minimize dilution with drilling of production or service support holes accurately and according to the plan. They can also be fitted with a V30 head for ø762 mm reaming in service support, or reaming up to ø445 mm holes with 12” hammers in rapid raising.
