Coal Washability And Calculations

Environmental control implications of generating electric .

This report presents the results of integrating coal washability and coal reserves data obtained from the U.S. Bureau of Mines. Two computer programs were developed to match the appropriate entries in each data set and then merge the data into the form presented in this report. Approximately 18% of the total demonstrated coal reserves were matched with washability data.
