“Our forthcoming Sandvik DD422i development jumbo provides a clear direction to the future of mining, incorporating a wide variety of new features for more efficient drilling,” says Alain Comorge, Sandvik product line manager, underground development drills.

The mining jumbo is the first of the Next Generation underground hard rock drill rigs from Sandvik, and also the first with an intelligent control system.

“DD422i development jumbo will be compatible with Sandvik AutoMine Drilling fleet and information management system and will be the most advanced underground mining drill on the market,” Comorge says.

DD422i offers the widest range of automated features on the market, including new drilling and boom control systems, full face drilling automation and drill rig navigation and industry-leading drill planning, analysis and optimization systems. Other key features are a “human detection system,” readiness for teleremote-operated functions, a ROPS/FOPS canopy, a redesigned and larger cab, improved visibility, brighter LED lighting and reduced noise, heat and dust levels.
