Treatment of Coal Liquefaction Wastewater by Solvent Extraction and Biological Nitrification?Denitrification

Refuse Recycling
The refuse recycling plant at Columbus, Ohio, is a pioneer in burning as fuel a combination of refuse and coal. This hybrid fuel has advantages over burning either alone. One winter in...

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...

Validation of Consolidation Properties of Phosphatic Clay at Very High Void Ratios
The void ratio-effective stress and void ratio permeability relationships for phosphate slime mine tailings were measured by several methods. The measurements were used in nonlinear finite...

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...

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,...

Application of Finite Strain Consolidation Theory for Engineering Design and Environmental Planning of Mine Tailings Impoundments
A knowledge of the consolidation behavior of mine tailings, during and after deposition, is important in estimating final impoundment capacity, rate and pore fluid expulsion during and...

Dredging for a new Port - Puerto Bolivar, Colombia
A major coal export terminal at Bahia Portete, Colombia, is being developed as part of the Cerrejon Coal Project - North Zone, where one of the world's largest coal mines...

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....

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...

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...
