An orange and silver drill rig (a tractor-like apparatus with two parallel arms that reach above the cab and then make a steep diagonal to the ground) and several red and silver drill rigs sit in the foreground of a silty construction site. Other equipment is in the midground and hills filled with evergreens and blue sky above in the background.

Construction crews start lowering equipment a mile underground for excavation for DUNE

How do you build a ship in a bottle? Everything necessary to construct the enormous Fermilab-hosted international Deep Underground Neutrino Experiment must fit down a narrow, mile-deep shaft cut through solid rock. Contractors have started the months-long process of disassembling excavation equipment and lowering it underground.

Rock transportation system is ready for excavation of DUNE caverns

Fermilab contractors have successfully commissioned a system that will move 800,000 tons of rock to create space for the international Deep Underground Neutrino Experiment’s detectors in South Dakota. Excavation crews will transport the rock from a mile underground to the surface using refurbished mining infrastructure and the newly constructed conveyor system.

One minute with Kate Sienkiewicz, LBNF Near Site Conventional Facilities project manager

From working at the CIA to designing science facilities at Fermilab, Kate Sienkiewicz enjoys tackling complex problems. Currently, she oversees the team tasked with designing and building conventional facilities at the Long-Baseline Neutrino Facility near site for the international Deep Underground Neutrino Experiment — all with the overarching goal of understanding the universe.

Un gigantesco laboratorio de neutrinos en Dakota del Sur a kilómetro y medio de profundidad

    From Público, Nov. 24, 2020: Homestake fue la mayor y más profunda mina de oro de de Norteamérica hasta que se cerró en 2002 tras 125 años de funcionamiento. Este remoto lugar de Dakota del Sur se convirtió oficialmente en 2007 en un laboratorio subterráneo de física fundamental, aunque ya mucho antes se habían instalado en sus profundas cavernas algunos experimentos, incluido uno que mereció el premio Nobel. Ahora se anuncia la nueva etapa para convertir la mina en sede del megaproyecto científico más importante de las últimas décadas en Estados Unidos, el Long-Baseline Neutrino Facility, dedicado a estudiar las partículas fundamentales llamadas neutrinos.

    Upgrades to Ross Shaft include new cage, skips and rope replacement

      From Sanford Underground Research Facility, Nov. 24, 2020: Another series of upgrades to the Ross Shaft is underway at the Sanford Underground Research Facility. Crews are working to outfit the shaft with new cage and skip conveyances and have replaced thousands of feet of hoist cables. The work prepares the Ross Shaft for its role as the main travel way for upcoming excavation and construction of the Long-Baseline Neutrino Facility to support the Deep Underground Neutrino Experiment, the world’s flagship neutrino experiment, which is hosted by Fermilab.

      Mining company to bring 110 jobs to Lead

        From Black Hills Pioneer, Nov. 17, 2020: Thyssen Mining Company, one of North America’s largest mining companies, has signed a three-year contract to excavate space for the Long Baseline Neutrino Facility at Sanford Lab in South Dakota. The company plans to bring about 110 jobs for miners, operators, mechanics, electricians, engineers, and managers. Thyssen Mining is currently preparing office space in Lead, as well as getting personnel lined up, contracting with local vendors, and preparing equipment for the project.

        Contract awarded for the excavation of gigantic caverns for the Deep Underground Neutrino Experiment

        This month, Thyssen Mining Inc. was awarded the contract to excavate the gigantic caverns for Fermilab’s Long-Baseline Neutrino Facility. Excavation crews will drill, blast and remove approximately 800,000 tons of rock to create the underground space for LBNF. When complete, the facility will house the enormous particle detector for the international Deep Underground Neutrino Experiment, hosted by Fermilab.
