       Notes: Productivity is calculated by dividing total coal production by the total direct labor hours worked by all employees engaged in production, preparation, processing, development, maintenance, repair, shop or yard work at mining operations, including office workers.  Excludes silt, culm, refuse bank, slurry dam, and dredge operations except for Pennsylvania anthracite.  Excludes mines producing less than 10,000 short tons and preparation plants with less than 5,000 employee hours, which are not required to provide data.
