RISProcesses Governing Flow and Chemical Characteristics of Discharges from Free-Draining, Underground Coal Mines
Publisher: American Society of Civil Engineers
Abstract: In the Uniontown Syncline of Southwestern Pennsylvania, discharges from unflooded, free-draining coal mines are acidic with high sulfate concentrations. Flow and water quality data obtained in 1998–2000 for an unflooded ...
Hydrologic and Geochemical Factors Governing Chemical Evolution of Discharges from an Abandoned, Flooded, Underground Coal Mine Network
Publisher: American Society of Civil Engineers
Abstract: Discharges from some underground flooded coal mines have exhibited increases in pH and reductions in contaminant loadings with time. Data from a study of mine water quality evolution in interconnected, flooded mines of the ...
