Late registrations will be accepted, but a $10 late fee ($5 for students) will be assessed for any reservation made after Friday. Cancellations within 7 days of the event will incur a fee equal to the registration fee.


The Deep Underground Neutrino Experiment (DUNE) will be the first internationally conceived, constructed, and operated mega-science project hosted by the Department of Energy in the United States. The project will advance the understanding of neutrino science The Long Baseline Neutrino Facility (LBNF) Far Site Conventional Facilities are essential infrastructure for the project. They are sited at the Sanford Underground Research Facility (SURF) located within the former Homestake Gold Mine in Lead, South Dakota. The project involves excavation and support of three large caverns which will house four 10 kT fiducial volume liquid argon (LAr) neutrino detectors and cryogenic equipment, as well as numerous ancillary connecting drifts and chambers.

This presentation will provide an overview of the project, the geological setting, the geotechnical investigation undertaken nearly a mile underground and the challenges associated with collection of reliable data in a high stress and geologically complex environment. The layout for the new facility will be presented, along with a description of some of the constraints that will impact construction methods and sequencing, including shaft access and working within an operating research facility. It will also describe an underground test blast program undertaken to develop site-specific vibration and overpressure attenuation data for design of production blasting, bulkheads, and laboratory protection measures.
