Utilization of Waste Materials in Civil Engineering Construction
Industrial growth has increased the volume of wastes generated from energy production, mining, industrial processes and civil works. For economic and related reasons, the use of waste...
Seismic Assessment of Tailings Dams
A significant portion of the operating and closed large dams in North America are tailings dams used to impound wastes from mining operations. Often these dams were built by mine personnel...
Interface Friction of Polypropylene Straps
Three-Dimensional Analytical Techniques for Assessing Overburden Toxicity as a Decision-Making Tool for Reclaimability Determinations
Radioelements and Their Occurrence with Secondary Minerals in Heated and Unheated Tuff at the Nevada Test Site
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....
Determination of Geotechnical Properties of Uranium Tailings
Roller Compacted Concrete Tailing Retention Dam
A roller compacted concrete (RCC) dam has been designed for gold tailing impoundment in southeast Alaska. To minimize up front capital costs, the curved gravity dam with multiple outlet...
Mitigation of Acidic Mine Drainage: Engineered Soil Barriers for Reactive Tailings
Properties and Environmental Impact of Stabilized Fly Ash
This paper summarizes the results of two research studies aimed at evaluating the properties and possible environmental effects of bituminous and lignite coal based fly ashes stabilized...
Acid Mine Drainage: An Overview
In the United States, acid mine water adversely affects over 6,500 km (4,000 miles) of rivers and streams. This is, however, a significant improvement over the situation two decades ago....
A Model to Predict the Production Rate of AMD
Results generated from a model to deterministically calculate the production rate of acid mine drainage compared to those generated by an empirical model are nearly identical. The model...
Wetlands for Acid Mine Drainage Treatment
Wetlands are being constructed on mined lands to treat acid mine drainage. Most of these wetlands remove a substantial amount of iron and sulfate from the water, but manganese removal...
Overview of Acid Mine Drainage Control Strategies
Since 1970, regulations requiring proper overburden sampling techniques to obtain representative geologic profiles and outline specific overburden analysis to determine acid-producing,...
Ash Disposal at Coal Creek Station
This paper outlines the effort of two utilities to minimize the impact of an 1100 megawatt lignite fired plant's waste stream on the environment. Current regulations, poor...
Beneficial Use of Coal Ash as a Structural Fill
For decades, electric utility companies have and will continue to dispose of their coal ash in various waste disposal sites. In the state of Pennsylvania, the Beneficial Use of Coal Ash...
Scientific Literacy and Public Education About High-Level Radioactive Waste
The citizens of the United States, and I would tend to believe of other countries, must be sufficiently science literate to make intelligent, rational decisions regarding energy and mineral...
Regulatory Requirements and Long-Term Repository Host Rock Performance
The regulatory requirements governing the disposal of high-level radioactive wastes in mined geologic repositories acknowledge the long-lived nature of the wastes and require the consideration...
Variation of Permeability with Temperature in Fractured Topopah Spring Tuff Samples
Fractures will play an important role in the near-field hydrology of a nuclear-waste package in a mined repository. Our previous studies showed that the water permeability of fractured...
Evaluation of Alternative MGDS Development Strategies
A methodology has been developed to explicitly and quantitatively evaluate acceptable alternative repository development strategies, in terms of the degree to which they are likely to...
