Book excerpt: This report outlines the program Environmental Control Technology Survey of Selected US Strip Mining Sites being performed at Argonne National Laboratory for the US Department of Energy. In addition, the report describes control technology efficiency for two mines in Pennsylvania and cost data for one of those mines. At the present time, mine drainage control and treatment at surface coal mines may not reflect conscientious planning and engineering design work by mine operators. On the whole, control technology (including reagent application) may be haphazard and periodically inefficient. Surface mine operators favor small, efficient, and above all, portable application systems for neutralization reagents. When choosing a reagent to neutralize mine drainage, reagent cost per unit quantity is less of a deciding factor to surface coal mine operators than ease of reagent application and handling. Costs for compliance with EPA/OSM effluent limitations can range from $3 to $7/ton. The higher costs are associated with steeply-sloped terrain.

Available in PDF, EPUB and Kindle. Book excerpt: An intensive study of water, overburden, and coal chemistry was conducted at a large surface mine in Ohio from May 1976 through July 1977. Sampling sites were chosen to include the final mine effluent at the outflow of a large settling pond and chemically-treated drainage from a coal storage pile. Samples were collected semimonthly and analyzed for total dissolved solids, total suspended solids, alkalinity, acidity, sulfate, chloride, and 16 metals. Field measurements included pH, flow rate, dissolved oxygen, and specific conductance. The final effluent, where sampled, generally complied with Office of Surface Mining reclamation standards for pH, iron, and total suspended solids. Comparison of the final effluent with water quality of an unnamed tributary above the mine suggested that elevated values for specific conductance, total dissolved solids, sulfate, calcium, magnesium, manganese, and zinc were attributable to the mine operation. In general, there were observable seasonal variations in flow rates that correlated positively to suspended solids concentrations and negatively to concentrations of dissolved constituents in the final effluent. Drainage from the coal storage pile contained elevated levels of acidity and dissolved metals which were not reduced significantly by the soda ash treatment. The storage pile drainage was diluted, however, by large volumes of alkaline water in the settling pond. Analysis of overburden and coal indicated that the major impact of mine drainage was pyrite oxidation and hydrolysis in the Middle Kittanning Coal and in the Lower Freeport Shale overlying the coal. However, the presence of a calcite-cemented section in the Upper Freeport Sandstone contributed substantial self-neutralizing capacity to the overburden section, resulting in generally alkaline drainage at this site.
