Variations in Curve Number for a Reclaimed AML Site
Runoff and erosion from an abandoned mine land site near Sheridan, Wyoming were monitored for four years following reclamation. Small plots, which included lengths from 12 to 24 meters...

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

Characterization of a Heavy Metal Contaminated Site

The Potential Fate of Particulate Contaminants from the Rehabilitated Ranger Uranium Mine
In the initial period after rehabilitation of the Ranger Uranium Mine most particulate matter released into Magela Creek will be wash load. 10% of the annual deposits on the backwater...

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

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...

Offshore Challenge
Standard design techniques weren't enough to create rigs for the Main Pass Mine, which, at 67 million long tons, is the largest offshore sulfur mine in U.S. history. The 18...

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...

Mining for Building Expansion
Engineers adapted mining techniques to tunnel under a vibration sensitive manufacturing operation to create new working space below. IBM workers needed more working space at their Vermont...

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...

Evaluating Advanced Technologies for Acid Rain Compliance
Technological innovation in emissions control of acid rain precursors has made possible increasingly stringent control requirements for coal-fired power plants. A key challenge for potential...

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...

Acid Mine Drainage Control Utilizing Fly Ash
Acid mine drainage is a serious environmental problem confronting the Appalachian region. Fly ash, the air particulate residual from the combustion of coal, is also an environmental concern...

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...
