Smart Drill

Atlas Copco say their new ROC F9C SmartRig (pictured) allows operators to design shot patterns on a computer and then follow through with GPS-guided, automated drilling for higher accuracy and speed.

Operators pre-plan their shot by entering the hole spacing, burden, depth and blast angle on a PC program that comes with the rig. By loading a memory card into the ROC F9C, the plan is then followed precisely, without the operator having to touch the controls. As well as accurate positioning, the ROC F9C adjusts the impact power and feed pressure according to the rock conditions, to achieve smoother drilling and reduced stress on the drill steel.

The rig can drill holes from 3in to 5in (90–125mm) in diameter and up to 98ft (30m) deep, with hole deviation typically less than 2in (5cm).
