Portugal’s mining strategy may favour copper over lithium
Portugal already has the largest copper mine in the European Union, operated by Lundin Mining.
The successor to the first fully mechanised cable-bolting rig from Sandvik, the well known Cabolt, the all-new DS421 benefits from the legacy of three decades of first-class cable bolters. Sandvik states: “Offering excellent safety, serviceability and efficiency – with a record of 13,000 metres of grouted cable bolts per month – the one man operated DS421 is a true boost for productivity.” The new Sandvik DS421 is designed especially for rock reinforcement in underground mines and tunnels with small and medium cross sections. With a working width of 3.9 m and a working height from 3.2 to 8.4 m, combined with a small turning radius, it is a good match for the 4 x 4 drift size class. As a self-contained unit with an onboard steel strand reel, a cement mixer and c cement bag platform, the DS421 can install cement grouted cable bolts up to 25 m in depth. (more…)
