Revolutionary Raise Boring Success in Scandinavia
Sandvik’s drilling tools have played a crucial role in a record-breaking raise boring achievement in Scandinavia. Drillcon Group completed a 700-metre ventilation shaft in a single pass for Zinkgruvan Mining in Sweden.
The project, part of the Dalby mine expansion, began in April 2024. The team drilled a 700-metre pilot hole downward before reaming it back up to a 4.1-metre diameter.
Sandvik’s cutting-edge raise boring tools ensured smooth execution. The team used the newly launched Sandvik RR890 pilot bit, an advanced 12EL reamer head, and modernised cutters featuring PowerCarbide technology. These tools delivered outstanding performance without requiring cutter replacements or reamer servicing.

“Completing a full raise without needing to replace the cutters or service the reamer is a remarkable achievement, and we are thrilled to have the Sandvik raise boring team supporting us in making this happen,” Drillcon Group production manager raise boring Jonas Myrzell said.
Sandvik’s RR890 pilot bit featured PowerCarbide inserts, full leg protection, and a patented dual-seal roller bearing. This technology extended service life and improved rock-breaking efficiency.
“We are thrilled with the successful raise boring results Drillcon achieved in this project, and the high expectations we had for our optimised raise boring tools were met,” Sandvik product manager raise boring Russell Clayton said.

Sandvik Secures Major Equipment Deal in Southeast Asia
Sandvik Mining and Rock Solutions has secured a significant underground equipment deal with a Southeast Asian mine. This deal marks a bold step towards adopting advanced mining technology and digital transformation.
The mine has invested in a comprehensive fleet designed for precise drilling, bolting, and material handling. This decision aligns with the industry’s shift towards efficiency, automation, and safety.
Advanced Equipment for Underground Expansion
The equipment package includes multiple DS422i development drills with hole diameter capabilities from 3.44 to 5.88 metres. These drills form the backbone of underground expansion, ensuring high-quality results with precision and consistency.
The DS422i drills also offer digital monitoring systems that track performance in real time. These insights help mine operators make informed decisions and optimise efficiency.
The order also includes DS422i cable bolters with a reach of up to 25 metres. These machines deliver crucial ground support while maintaining tunnel integrity. Automation and AI integration enhance safety and minimise downtime.
For material handling, the mine has ordered Toro LH410 loaders with bucket capacities between 4 and 5.4 cubic metres. These loaders balance compact manoeuvrability with high productivity. Intelligent systems optimise motion and fuel consumption for better efficiency.
Toro TH663i trucks complement the fleet with box capacities ranging from 24 to 40 cubic metres. Their robust design allows them to perform reliably in demanding underground conditions. These trucks integrate seamlessly with automation systems for enhanced efficiency.
Rounding out the package is the DB331 secondary breaker. With a reach of 11.33 metres, it fragments oversized rock to maintain a steady material flow. This prevents production bottlenecks and protects downstream equipment.
Scheduled Deliveries and Operational Integration
The equipment deliveries will begin in the second quarter of 2025, with the final units expected in early 2026. This phased rollout allows for gradual training and integration, minimising disruptions.
The delivery schedule aligns with the mine’s long-term strategy. Mining operations often require up to 18 months from order placement to full implementation. This structured approach helps mine managers prepare maintenance facilities and upgrade communication networks.
The planned rollout reflects broader industry trends. A well-paced integration ensures that operators receive necessary training on automation systems, including digital twins for improved efficiency.
Innovations in Automation and Safety
The equipment package includes advanced automation features that transform traditional mining practices. A key highlight is the Platinum automation package, which offers automatic boom movements and collision avoidance.
The system uses advanced sensors to create a protective virtual envelope around machinery. This reduces accidents and boosts operator confidence. Studies have shown that automated mining processes improve productivity by 15–25%.
By reducing operator fatigue and enhancing real-time data monitoring, automation ensures better maintenance planning and fewer unexpected breakdowns. These advantages significantly improve safety and operational reliability in underground mining.
Technical Specifications and Equipment Performance
The DS422i development drills are designed for multiple applications, including long-hole production and cable bolting. Their consistent drilling quality reduces the risk of blasting delays.
The power management system on these drills improves energy efficiency by up to 18%, lowering operating costs and reducing underground ventilation requirements.
Toro LH410 loaders support medium-sized mining operations with production rates of up to 400 tonnes per hour. Their compact design ensures smooth navigation in narrow tunnels.
Toro TH663i trucks transport payloads of up to 63 tonnes, ensuring efficient material movement. Their intelligent transmission system adjusts performance based on terrain and load conditions.
The DB331 secondary breaker delivers precise hydraulic breaking force. It adapts to different rock sizes while maintaining a steady material flow.
Digital monitoring systems ensure all equipment operates at peak performance. Operators receive real-time alerts, streamlining maintenance and preventing costly downtime.
A Strategic Move for the Future
The mine’s decision to invest in Sandvik’s high-tech equipment reflects a commitment to innovation and sustainability.
Equipment reliability was a key factor in the purchase. Similar operations have reported over 90% uptime with Sandvik machines.
The mine’s focus on automation aligns with the mining industry’s decarbonisation trends. This shift aims to reduce operational hazards and environmental impact.
Integrating multiple machine types from a single manufacturer streamlines operations. This creates a cohesive system rather than isolated equipment improvements.
With automation improving safety and productivity, the long-term cost benefits of these investments become clear. The mine is positioning itself for sustainable growth while ensuring a strong return on investment.
Emerging Trends and Future Innovations
Sandvik continues to lead innovation in the mining sector. Recent upgrades to the DD210 narrow vein underground drill rig have improved drilling speeds by 20% in confined spaces.
New additions to the X-series rotary blasthole line offer flexible drilling patterns and enhanced feed systems for greater precision.
The upgraded iSURE drill and blast software improves fragmentation prediction, reducing blast overbreak by up to 30%. This enhances ore extraction and minimises dilution risks.
Sandvik is also expanding its battery-electric loaders and trucks to support zero-emission mining. These machines reduce ventilation needs and lower operating costs.
Digitalisation remains a priority with platforms like OptiMine®, which enables remote monitoring and predictive maintenance. These innovations help mines achieve long-term efficiency and sustainability.
With continued advancements, Sandvik strengthens its position as a leader in mining technology and automation.
