Sandvik has unveiled its next-generation automated development drill rig that‘s built on legacy and driven by the future — the DD423i.
Built on the legacy and unmatched performance of the DD422i, which has been the leading development drill in the underground mining industry for more than a decade, the DD423i raises the bar for productivity, intelligence and reliability in underground development drilling.
“The introduction of the DD423i is an important milestone for Sandvik,” said Simon Morrissey, product manager for Development Drills.
“The DD422i set the benchmark for development drilling in 2015 and its success over the past decade has shaped the industry. With the DD423i, we honor that legacy while delivering a future‑ready drill designed for even higher performance, automation and safety,” added Morrissey.
Delivering 34.5 percent more drilling coverage and 48% improved cross‑cut performance, the DD423i introduces new SB75i booms with double roll‑overs for superior reach in confined spaces, such as room‑and‑pillar applications. Automatic boom movements and integrated boom‑collision avoidance provide faster, safer and more precise drilling cycles.
In field testing in Boliden, in the Skellefteå region of Sweden, the DD423i achieved more than 95 percent machine availability, highlighting Sandvik’s commitment to robust and dependable equipment.
“The Skellefteå region is known for its extremely hard and abrasive geological conditions. It is one of the toughest areas for rock drilling in Scandinavia and therefore provided the ideal testing conditions for the DD423i,” said Morrissey.
The redesigned cabin on the DD423i delivers a step forward in operator safety and comfort, offering 55% increased visibility, lower noise levels and improved dust control. Enhanced serviceability with easy access to key components supports quicker maintenance and reduces downtime. The advanced drilling control system provides fast and accurate performance with intuitive operation for all skill levels.
The DD423i is fully compatible with Sandvik digital mining solutions, including Sandvik iSURE®, Sandvik DrillConnect, Sandvik iNav total station navigation, My Sandvik Remote Monitoring, and the Newtrax Mining Data Platform, enabling a connected, data‑driven approach to development drilling.
