Ground-Water Investigation at Two UMTRA Sites
Modeling of Moisture Penetration through Cover for Uranium Mill Tailings Site
Biochemical Oxidation of Solvent Extracted Coal Gasification Process Wastewater
Treatment of Coal Liquefaction Wastewater by Solvent Extraction and Biological Nitrification—Denitrification
The Theory of One-Dimensional Consolidation of Saturated Clays
The theory of nonlinear finite strain consolidation is reviewed. A modification of the effective stress equation to account of settling and consolidation as a unified phenomenon is proposed....
Particle Interaction and Stability of Suspended Solids
The physics of particle interaction, which is responsible for the problem of the apparent tardy settling of suspended solids in tailings discharge slurries containing initially low concentrations...
Reporter's Summary: Prediction and Validation of Consolidation for Hydraulically-Deposited Fine-Grained Soils
Prediction of Viable Tailings Disposal Methods
A sand-fines-water diagram is proposed to analyze and describe slurries composed of coarse and fine particulate matter. The diagram can be used to predict and plan disposal methods for...
Waste Phosphatic Clay Disposal in Mine Cutsr
Research was undertaken to assess the applicability of waste clay disposal back into phosphate mine cuts. The pit was monitored for two years with measurements of clay surface elevation,...
Movement of Tractive Sediment from Disturbed Lands
The Smoky Creek basin of the coal area of northeastern Tennessee shows extensive evidence of tractive movement of coarse sediment from mined tributary basins into the main channel. Coal-rich...
Decision Analysis of Coal Ash Disposal Technology
Coal-fired power plants produce a number of solid waste streams in the course of their operation. These coal combustion by-products (CCBPs) are composed of fly ash, bottom ash and boiler...
Predicting Ground-Water Drainage to Surface Mines
A two-dimensional, finite-difference numerical model is used to simulate the drainage of ground water into a surface coal mine. Graphs of dimensionless head as a function of dimensionless...
Leaching Analysis of Coal Mine Spoil Material
Arch Mineral Corporation has conducted a column leaching study to analyze the leaching characteristics of surface coal mine spoil material in order to predict post-mining groundwater quality....
Effects of Resource Development on Water Quality in the Big South Fork National River and Recreation Area, Tennessee and Kentucky
The South Fork Cumberland River begins in Tennessee at the confluence of the New River and Clear Fork. Strip mining for coal in the New River basin has been ongoing for decades with little...
Validating Predictions of Tailing Embankment Behavior with the Centrifuge
A Quantitative Assessment of Surface Water Resources for Coal Slurry Pipelines Originating in Southwest Virginia
In view of the high streamflow variability, preliminary quantitative assessment was made of the capacity requirements and low-flow frequency characteristics of offstream reservoirs needed...
Consolidation of Mining Wastes
This paper describes laboratory and field tests for determining consolidation properties of soft sediments, presents data on several types of mining wastes, and presents the results of...
HELP Model Applications to Percolation through Uranium Mill Tailings Remedial Action Cover Systems
Lining a Pond to Contain Uranium Tailings
Impermeable pond linings combined with geotextile fabric underlinings are a recent innovation in industrial storage pond construction. A case history of a pond site in New Mexico illustrates...
