The Cascades Proposal for the Deep Underground Science and Engineering Laboratory [PDF]
Nuclear Physics B - Proceedings Supplements, 2011 One of the options for creating a Deep Underground Science and Engineering Laboratory (DUSEL) is a site in the Mt. Stuart batholith, a granodiorite and tonalite rock mass in the Cascade mountain range in Washington State. The batholith's 100-year history in hard-rock tunneling includes the construction of the longest and deepest tunnels in the U.S ...

Mechanism Study and Tendency Judgement of Rockburst in Deep-Buried Underground Engineering
Minerals, 2022 Rockburst is a type of dynamic instability failure phenomenon and frequently brings huge losses to underground engineering projects such as mines and tunnels. In order to explore rockburst mechanisms and predict rockbursts better, relying on the background of Wulaofeng deep-buried highway tunnel, in situ stress measurement was performed using new ...
