A quartz crystal vein was intercepted at the 4,550-foot level. The crews were amazed the quartz crystals were not destroyed by the reamer’s cutting wheels.
Thyssen Mining excavation crews in Lead are preparing the Long-Baseline Neutrino Facility for the Deep Underground Neutrino Experiment known as DUNE, hosted by the U.S. Department of Energy’s Fermi National Accelerator Laboratory and supported by the DOE Office of Science. In a project that requires the excavation of 800,000 tons of rock, they have carefully navigated the challenge of the raise-bore drilling stage.
Some magnificent sights are hard to capture well in photos that truly convey their grandeur and magnitude. Consider the gargantuan cliffs of Y…
