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...
Design of Pena Colorada Tailings Retention Dam
This paper discusses the details involved in the design of a 66 meter high RCC dam to be used to create storage for slurry from an iron ore mining operation located near Manzanillo, Mexico....
Coal-Gas Conundrum
Manufactured gas from coal brought streetlights and clean cooking fuel to the late Victorian era, but a hundred years later their legacy isn't quite so beneficial. Investigators...
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....
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...
Technology?Key to Environmental Success
A three million ton per year coal unloading terminal with 5 km overland conveyor at Jacksonville, Florida, incorporates numerous technical advances to achieve environmentally safe construction...
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...
Fly Ash Grouts for Subsidence Control
A laboratory investigation was undertaken to examine procedures for evaluating candidate grouts and to develop quality grouts for use in abandoned mines. The objective of this grout application...
Leachate Flow from an Experimental Fly Ash Landfill
Combustion of coal in large-scale utility boilers produces an ash by-product which is often stored in open landfills. An experimental fly ash landfill was constructed by Pennsylvania Power...
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...
Assessment of Fracture-Sampling Techniques for Laboratory Tests on Core
As part of the site characterization work to be done at Yucca Mountain in Nye County, Nevada, a candidate site for the first mined-geologic repository for high-level nuclear waste, laboratory...
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...
Yucca Mountain Near Field Environment Considerations for Engineered Barrier System Design and Performance
Waste emplacement environment will be essentially dry for at least 300 years and will likely continue to be dry for more than 1000 years, both as a result of the unsaturated ambient conditions...
