Sandvik Mining and Rock Solutions is introducing the Sandvik DD312i, a new intelligent, compact and automated single-boom jumbo. Capitalising on 20 years of drilling legacy from the Axera D05 to Sandvik DD311, the Sandvik DD312i now joins Sandvik’s i-series range of intelligent development drills.
The Sandvik DD312i is a versatile drill for face drilling, cross cutting and bolting, and can be used in development and production drilling in room and pillar, cut and fill, stoping or caving mining methods.
It is a compact machine suitable for medium-to-large sized underground drifts; its compact carrier with canopy or cabin options and its small cornering profile allow it to fit into the tightest operations. The Sandvik DD312i features the modern, ergonomic and spacious cabin now standard across the 400i and 300i series drills.
The new intelligent control system with torque optimised drilling is designed for mines seeking more tonnes with maximum profitability. Miners can enjoy up to 50% increased drilling accuracy, up to 26% more drilling coverage and up to 20% more productivity when combined with Sandvik’s scalable automation packages for drills.
“During field testing with La Cantera in Mexico, Sandvik DD312i demonstrated up to 28% increased total productivity, better service life for tools and lower bits and consumables consumption,” said Jean François Haen, Product Manager for Sandvik’s 300-range of single-boom development drills and bolters. “La Cantera’s maintenance manager highlighted the strong savings on feed buffers, water hoses and rock tools during the testing period, and the operators were impressed by the easy transition to Sandvik i-series drills.”
Sandvik will simultaneously launch the Sandvik DD312i Digital Driller® training simulator for fast and easy operator training before the machine arrives at site. Sandvik DD312i is also compatible with Sandvik’s underground drilling digital offering including Sandvik DrillConnect and iSURE® 9.0.
