Deep Underground Science and Engineering Laboratory Site and Conceptual Design

该项目建议为位于Empire， CO.的亨德森矿山的深部地下科学与工程实验室DUSEL制定一个概念设计方案。该矿山归Climax钼公司所有，该公司是Phelps Dodge Corp.的子公司，是一个正在运营的矿山，也是世界上最大的矿山之一。该矿业公司拥有DUSEL所需的所有土地，包括尾矿场，并已完成开发DUSEL所需的所有许可。一个全国性的组织，亨德森地下科学与工程项目（HUSEP）合作组织已经成立，以指导亨德森DUSEL的开发。这将涉及开发一个位于2500-3300米水当量（mwe）深度的上校区，用于只需要中等覆盖层的实验，一个位于4200 mwe的中央校区用于需要更大深度的实验，以及一个位于6000 mwe的下校区用于需要更大深度的实验。这些矿区将在目前正在开采的矿区附近的山上开发，因此可以使用为正在开采的矿区开发的所有基础设施。通过岩心钻探，该岩石已被很好地表征至2500 mwe的深度；它似乎是高活性的斑状花岗岩，裂缝面少，水少。当地社区大力支持亨德森DUSEL，这在合作的教育和推广计划中发挥了作用。一个现有的外展计划，包括雪原地区大时间巧合阵列（SALTA），将是这一外展计划的一个组成部分，尽管它的影响将通过涉及地区高中学生和教师而扩大。还将开发一个游客中心，矿山旅游将成为该计划的一部分。

This proposes to develop a conceptual design plan for a Deep Underground Science and Engineering Laboratory, DUSEL, at the Henderson Mine at Empire, CO. The mine is owned by the Climax Molybdenum Company, a subsidiary of Phelps Dodge Corp. It is an operating mine, and is one of the largest in the world. The mining company owns all the land necessary for the DUSEL, including the tailings site, and has done all the permitting necessary to develop the DUSEL.A national organization, the Henderson Underground Science and Engineering Project (HUSEP) Collaboration has been formed to guide the development of the Henderson DUSEL. This would involve development of an upper campus, at a depth of 2500-3300 meters of water equivalent (mwe) for experiments requiring only a moderate overburden, a central campus at 4200 mwe for experiments requiring somewhat greater depth, and a lower campus at 6000 mwe for experiments requiring great depth. These would be developed in a mountain adjacent to that currently being mined, so would have access to all the infrastructure developed for the operating mine. The rock has been well characterized to a depth of 2500 mwe by a core drilling; it appears to be highly competent porphyritic granite with few fracture planes and little water.The local community is strongly supportive of Henderson DUSEL, and this plays into the education and outreach plans of the collaboration. An existing outreach program, involving the Snowmass Area Large Time-coincidence Array (SALTA) would be one component of this outreach, although its impact would be expanded by involving regional high school students and teachers. A visitor center would also be developed, and mine tours would be part of the program.
