Interface Friction of Polypropylene Straps

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...

Three-Dimensional Analytical Techniques for Assessing Overburden Toxicity as a Decision-Making Tool for Reclaimability Determinations

Two Examples of Position Estimation

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

Modifications to Coal Pier 6 Made Necessary by a Deeper Channel
In 1987 it became apparent to the Norfolk Southern Corporation that the U.S. Army Corps of Engineers proposed dredging of the Norfolk, Virginia Harbor would become a reality. Coal Pier...

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...

Mitigation of Acidic Mine Drainage: Engineered Soil Barriers for Reactive Tailings

Institutional Constraints to the Use of Coal Fly Ash in Civil Engineering Construction

Coal Mine Waste Formation and Changes of Microstructure Under Artificial Salting

Highway Construction Use of Wastes and By-Products

Design of Large Capacity Coal Silos for Service Life
Design and construction of Large Capacity Coal Silos for service life requires a careful consideration of the silo configuration as well as the material handling system. This paper presents...

Condition Assessment Experience with Silos and Bunkers
This paper presents a methodology for condition assessment of coal silos and bunkers for retrofitting projects. Some typical problems such as corrosion, erosion, vibrations and buckling...

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...

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...
