Electric trolley trucking towards fossil-free mining

Global technology company ABB is working with mining company Boliden and mining and infrastructure equipment manufacturer Epiroc to develop and demonstrate an electric trolley truck system on a test track at Boliden’s Kristineberg mine in northern Sweden.

Funded by the Swedish innovation agency, the development project by the three companies will enable heavy transportation with electric driven battery vehicles and is expected to lower CO₂ emissions and improve the work environment at the underground copper-zinc mine.

Boliden also plans to implement full scale electric-trolley systems in the Rävliden mine, a satellite orebody and extension of the Kristineberg mine.

The system will build on Epiroc’s zero emissions mining haul truck Minetruck MT42 Battery which is highly suitable for long haul ramps. It will feature a trolley pantograph which is to be connected to an overhead contact power line.

“We are very proud to enter this collaboration and are excited to jointly take the next steps on Boliden’s journey towards a fossil free, automated underground mine,” said Lars Bergkvist, Global Key Customer Manager with Epiroc’s Underground division. “Our electrification systems are well proven globally and contribute to substantial reduction of CO₂ emissions, leading to a smaller environmental footprint.”

ABB will provide electrical infrastructure design drawing on the its Ability eMine integrated electrification and digital systems. ABB will also provide the electric trolley truck system design, definition of standards and vehicle interface, as well as rectifier substation for the test track.

“ABB is supporting mining companies’ electrification strategies by working together with OEMs, such as Epiroc, and many other technology innovators to build an interoperable system and help fast-track the development of emissions-reducing systems,” said Max Luedtke, Global Head of Mining, ABB. “No company can do this alone and through our recently-launched ABB Ability eMine portfolio, we can ensure electrification and automation of the whole mining operation, combining solutions with others to lower CO₂ and move towards a more sustainable society.”
