Future Concept Study
The latest generation Atlas Copco Mobile
Miners
A project together with Rio Tinto for rapid development of access and haulage drives
in block cave mines
Overall goal with the project: Average 10-12 m/day advance
Rio Tinto’s Kennecott Utah Copper mine in Salt Lake City will be the trial site in 2013
