MineARC systems specializes in designing and custom building refuge chambers for the safe retreat of personnel engaged in tunnelling and underground construction. MineARC tunnel refuges perform the same life-preserving functions as standard mine refuge chambers, but are built to meet the specific needs of individual projects. They can be TBM-mounted, rail mounted or stand-alone, in electric or liquid carbon dioxide powered configurations. For more, visit www.minearc.com/tunnelsolutions. 43/13.
