The companies Boliden, Epiroc and ABB have inaugurated the first underground electric trolley system (trolleybus), deployed in a mine in Sweden. This system has been tested on an 800-meter track with an inclination of 13%, consolidating the realization of a completely electric mine.
The first underground electric mining car system
Boliden has highlighted the positive alliance between ABB and Epiroc that has lasted three years, highlighting both the immediate benefit to Boliden’s operations, as well as the potential to adapt this technology at other mines. This collaboration focuses on practical implementation, and on promoting technological development in the mining sector .
[post_relacionado]The project highlights the growing importance of critical minerals , necessary for the transition to clean energy, with demand that could increase towards 2030. Boliden plans to expand the application of this technology at the Rävliden mine, where the autonomous electric trolley system is expected to contribute to future Swedish mining projects.
Electrification also manages to reduce emissions and costs, while considerably improving safety in mines. Epiroc has incorporated advanced technology into its Minetruck MT42 SG trucks, improving their performance and efficiency , while ABB has developed the essential infrastructure from network to wheel.
