Deep Underground Science and Engineering Laboratory Site and Conceptual Design

本项目拟为帝国公司亨德森矿的深层地下科学与工程实验室DUSEL制定概念设计计划。该矿由菲尔普斯道奇公司的子公司Climax钼业公司所有，是一个正在运营的矿山，是世界上最大的矿山之一。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。这将涉及开发一个上层校园，深度为2500-3300米的水当量（mwe），用于只需要适度覆盖层的实验，一个中心校园，深度为4200 mwe，用于需要更大深度的实验，以及一个6000 mwe的下层校园，用于需要更大深度的实验。这些矿区将在与目前开采的矿区相邻的一座山上开发，因此可以使用为运营矿区开发的所有基础设施。通过岩心钻探，岩石的特征已被很好地描述为2500 mwe的深度;它似乎是高度胜任的斑状花岗岩，几乎没有断裂面和水。当地社区强烈支持亨德森DUSEL，这也有助于合作的教育和推广计划。现有的一个外联方案涉及雪团地区大型时间重合阵列（SALTA），将是这一外联方案的一个组成部分，尽管其影响将通过让地区高中学生和教师参与而扩大。还将开发一个游客中心，矿山图尔斯之旅将是该计划的一部分。

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.
