Boliden’s Sustainable Mining Revolution at Kristineberg

The quest for sustainable mining practices has taken a significant leap forward with the recent advancements in mining electrification technology. At the forefront of this evolution is the collaborative effort between Boliden, Epiroc, and ABB, which has culminated in the successful deployment of a fully battery-electric truck trolley system at the Kristineberg mine in Sweden. This initiative not only marks a pivotal step towards reducing carbon emissions but also sets a benchmark for future mining operations worldwide.

Unveiling the Test Track: Boliden’s Electrification Milestone

In the depths of northern Sweden, Boliden’s Kristineberg mine has become the stage for a remarkable technological showcase—a battery-electric truck trolley system designed to challenge the status quo of mining operations. The system features Epiroc’s Minetruck MT42 SG, a vehicle that has been enhanced with dynamic charging capabilities, and ABB’s innovative eMine Trolley System. This 800-meter test track with a 13 percent incline represents not just a trial of new technology but a glimpse into the future of mining.

The electrification of the mining fleet at Kristineberg is expected to yield significant environmental and operational benefits. By eliminating the use of diesel fuel, the mine reduces its CO2 emissions dramatically, contributing to global efforts against climate change. Furthermore, the electric system introduces a healthier work environment, cutting down on the emissions, noise, and vibrations typically associated with traditional mining operations. These changes not only favor the planet but also enhance the productivity and safety of the workers, creating a more sustainable and cost-effective mining operation.

Overcoming Challenges in Harsh Environments

Adapting to the rugged underground environment of a mine is no small feat for electrification technologies. The partnership has tackled these challenges head-on by developing a robust system capable of withstanding the hot and humid conditions underground. The integrated trolley system supports the truck on steep inclines, ensuring efficiency without compromising the demanding nature of its tasks. This section of the mine now serves as a proving ground for scaling these technologies, ensuring that the electric trucks can operate under the most challenging conditions.

Looking ahead, Boliden plans to extend this pioneering technology to the Rävliden mine, an expansion of the Kristineberg operations. This move will not only increase the mine’s operational area but also serve as a real-world application of an autonomous electric-trolley system across a 5 km stretch. The anticipated reduction in carbon emissions and the potential to set new standards for mining operations worldwide reflect a significant stride towards the industry’s sustainable future.

Boliden’s efforts at Kristineberg are paving the way for the future of mining. Through strategic collaboration and technological innovation, the project not only advances the goal of an all-electric mine but also demonstrates the tangible benefits of such advancements. As the industry watches and learns from these developments, Boliden, Epiroc, and ABB continue to drive the evolution of mining towards a more sustainable and efficient era.
