A conveyor belt over Main Street in Lead is planned to carry 800,000 tons of rock from the Sanford Lab to the Open Cut as work begins on an international underground neutrino experiment, reports the Black Hills Pioneer.
The rock is being excavated from the Ross Campus so that the Long Baseline Neutrino Facility (LBNF) can be built underground in the former Homestake gold mine. The LBNF is one part of the Deep Underground Neutrino Experiment (DUNE), which involves another facility at Fermilab near Chicago shooting a beam of neutrinos to particle detectors at the Lead facility.
Removing the rock will make way for four $90 million liquid argon detectors, each needing a 500-foot long detector chamber. In addition, a 625-foot-long central utility cavern is being excavated.
The city must approve an easement for the conveyor belt to operate. Plans are to move rock from 7 a.m. to 5 p.m. on weekdays.
