Sandvik Mining is introducing a new pumpable resin system for fast and reliable support in challenging ground conditions.

The new system is available for Sandvik DS412i and Sandvik DS412iE underground drill rigs and supports self-drilling bolts (SDB) and hollow bar bolts (HBB). It is compatible and optimised for Sandvik ground support products including the DSI Hollow Bar System and Mineral Bolt pumpable resin.

The combination of the pumpable resin system with intelligent i-series machines “ensures optimal performance and enhanced safety, quality and productivity in bolting applications.”

The new system supports one-bolt automation sequences for consistent quality and fast and reliable ground support, even in difficult ground conditions. The completely sealed resin system ensures no manual handling of chemicals, and the mixing ratio, filling ratio and filling volume are automatically controlled, only using the amount of resin required for the hole. The large onboard resin capacity reduces refilling times, and the Mineral Bolt pumpable resin offers fast and adjustable curing times, leading to faster re-entry to recently supported ground.

“During field testing at a customer site in Spain, we achieved a 95% success rate in pull-out tests, despite the challenging rock conditions,” said Ari Kopperoinen, Product Line Manager, Rock Support Drills, Sandvik Mining. “The successful ground support installation can be attributed to the combination of our Sandvik DS412iE battery-electric bolter with self-drilling bolts and Mineral Bolt pumpable resin from the DSI Hollow Bar System.”

Sandvik Ground Support offers pull-out testing services for better quality control in the bolting cycle. The Pumpable Resin System is also available as a custom order for Sandvik DS512i machines.

Sandvik said the new system demonstrates how it is setting a new standard in underground bolting with aligned end-to-end solutions for customers.
