The environmental aspects of mining have received little analysis. U.S. coals vary in moisture content 2 to 40%, sulfur content 0.2 to 8% and ash content 5 to 40% . The energy content varies from lignite to sub bituminous to bituminous coal. The ORNL RFF study looks at two levels of sulfur content 0.7% and 2.1% .

2020 5 13   Coal that occurs at depths of 180 to 300 ft 50 to 100 m are usually deep mined, but in some cases surface mining techniques can be used. For example, some western U.S. coal that occur at depths in excess of 200 ft 60 m are mined by the open pit methods, due to thickness of the seam 60–90 feet 20–30 m .
