This report relates to the actual costs of 78 classes of purchases made by the U.S. bituminous coal and lignite industry for its processing activities during 1958 and 1963. These purchases, or inputs, are separated into two broad classes comprising operating supplies excluding fuels and electricity and those parts and materials, having a service life less than 3 years, which were used for repair and maintenance activities. Also included in this report are descriptions of the major processes and methods employed in the 1958-63 period, trends in operating practices, the shift in the mix of processes employed, and the actual costs of inputs for specific activities and processes. Inputs for which no detailed cost data are available are listed as areas for future research. This study provides a better understanding of the impact on the supplying industries by the changing demands for inputs and their interrelationship to other sectors of the national economy.
