Boliden opened its “nearly fossil-free” Rävliden extension of the Kristineberg mine in Sweden in mid-Could and, in keeping with Epiroc, the 5-km electrified ramp haulage answer in place is already rising productiveness.
On Could 16, the Rävliden extension of the Boliden Space’s Kristineberg mine was opened, with Sweden’s Minister for Local weather and the Setting, Romina Pourmokhtari, in attendance.
Marking the supply of one among Boliden’s most climate-focused investments so far, the brand new extension of Kristineberg is constructed with a very fossil-free underground mining operation because the overarching goal.
This implies a largely electrified automobile fleet and infrastructure, together with the 5-km electrical trolley line for hauling the ore from a depth of 750 m to the floor.
In Epiroc’s June quarter outcomes, launched as we speak, the corporate’s President and CEO, Helena Hedblom, stated the trolley answer in place on the operation had elevated productiveness by 23%.
She added: “The truck velocity up ramp is 50% increased, the upkeep value is decreased by 25% and the vitality regeneration to the battery when the truck goes downhill and/or is linked to the pantograph is limitless.”
This electrified ramp haulage answer is the results of a collaboration between Boliden, ABB and Epiroc.
Epiroc supplies the Minetruck MT42 SG Trolley vehicles, which have been tailored from the OEM’s battery-electric Minetruck MT42 SG, that includes three battery subpacks versus the usual 5 subpacks the battery-only machine is often outfitted with.
ABB and others present the supporting infrastructure. The on-board truck infrastructure contains ABB’s DC-DC converter, HES880 inverters and AMXE motors to reinforce the ability of the machine, whereas there are off-board rectifier substations for the observe. The ABB Capability™ System 800xA® screens and controls {the electrical} system, whereas Siemens offered on-board {hardware} for the MT42 SG Trolley truck.
Exterior of the battery trolley answer, Boliden can also be utilizing, or plans to make use of, a lot of battery-electric manufacturing and assist machines to realize its finish objective of fossil-free operations at Rävliden.
Through the opening in Could, Kristineberg Mine Supervisor, Erik Fjällström, stated: “I’m so blissful and happy with what now we have achieved. This new a part of Kristineberg consumes 80% much less diesel than a traditional underground mine and that makes an enormous distinction for our local weather footprint. Nonetheless, we’re aiming for 100% fossil-free and proceed to push each ourselves and our suppliers to realize this.”
