Characterizing the Altered Zone at Yucca Mountain: The Beginning of a Testing Strategy

Two Examples of Position Estimation

Sulfur as a Lunar Resource
Sulfur on the Moon may prove to be a satisfactory replacement in some uses for lighter volatile elements and their compounds. Although sulfur is not richly concentrated on the Moon, it...

Environmental Aspects of Lunar Helium-3 Mining
Three potential detrimental effects of lunar 3He mining have been identified; visual changes, atmospheric contamination, and solid waste disposal....

Extraterrestrial Resources: A Perspective from Terrestrial Economic Geology
Terrestrial mining experience indicates that the overwhelming criterion of a potentially economic deposit is its recoverable concentration of the desired mineral or element. These criteria...

Beneficiation of Lunar Rocks and Regolith: Concepts and Difficulties
Considerations of the resources which can provide feedstocks of ilmenite, glass, agglutinates, anorthite, etc. at a lunar base require an appreciation of the geology of the situation....

Lunar He-3 Mining: Improvements on the Design of the UW Mark II Lunar Miner
One of the minor consituents of the solar wind which has been implanted in the lunar regolith over its several billion year history, is helium 3 (He-3), a rare isotope of helium which...

Lunar Surface Mine Feasibility Study
This paper describes a lunar surface mine, and demonstrates the economic feasibility of mining oxygen from the Moon. The mine will be at the Apollo 16 landing site. Mine design issues...

Lunar Surface Mining Equipment Study
In response to the Space Exploration Initiative (SEI), a large number of lunar base scenarios have been proposed by various members of the research community. The National Aeronautics...

Ropeway Material Handling Systems for Lunar Mining Sites
The establishment of permanent lunar sites will be a requirement for future space explorations during early missions into space as well as long term. During all stages it will be necessary...

Beneficiation and Comminution Circuit for the Production of Lunar Liquid Oxygen (LLOX)
A complete lunar beneficiation and comminution circuit has been designed that requires no air or fluid locks for feed introduction or egress, with the exception of a vapor pyrolysis station....

Transfer of Terrestrial Technology for Lunar Mining
Terrestrial mining equipment was evaluated for development of concepts and their application to lunar-based mining operations. The major operational differences between terrestrial and...

Spiral Mining for Lunar Volatiles
Lunar spiral mining, extending outward from a periodically mobile central power and processing station represents an alternative for comparison with more traditional mining schemes. In...

Preliminary Design of an Underground Lunar Mine
This paper presents a mining engineering viewpoint on the design and construction of an underground lunar mine. Upon completion, the facility will serve as a lunar habitat. Ore removed...

Design Criteria for an Underground Lunar Mine
Underground excavation and construction techniques have been well developed terrestrially and provide an attractive option for lunar mining and habitat construction. The lunar mine, processing...

Lunar Mining—Surface vs. in Situ—A Comparative Study
Surface mining and in situ mining are briefly reviewed and compared. It is verified that the inherent advantages of in situ mining over surface ruining point out that in situ mining should...

Outpost Service and Construction Robot (OSCR)
The Outpost Service and Construction Robot (OSCR) is proposed as the prime mover of a comprehensive, synergistic approach to extraterrestrial surface construction, mining and transportation...

Regulatory Law and Policy to Support Space Mining
Adaptation of modern mining law principles, such as those embodied in the U.S. General Mining Law of 1872, would protect mineral resource interests in space. A good illustration of a closely...

Determination of Geotechnical Properties of Uranium Tailings

Hydrologic Considerations in Mined Land Reclamation
Thunder Basin Coal Company (TBCC), a subsidiary of the Atlantic Richfield Company, operates the Black Thunder Mine in the Powder River Basin of Northeast Wyoming. The mine, located roughly...
