Application of a Coal Pile Drainage Model to an Industrial/Institutional Site

摘要

The report describes the site selection, field sampling and analysis and mathematical model calibration and verification process used to apply a coal pile drainage model to an industrial/institutional site (e.g., a small storage pile of less than 25 tons). The field program included 10 weeks of monitoring drainage flow, pH, conductivity, precipitation, coal moisture, and pile infiltration rates with the analysis of drainage water for acidity, filterable and nonfilterable residue, sulfate and 10 trace metals. Five storms were sampled ranging from 0.62 inches to 1.59 inches of rain. The pH metal concentrations exceeded NYS Department of Environmental Conservation effluent limitations for Class GA waters before treatment.
