subbtiminous coal produced by suface mining

Subbituminous and bituminous coal dominate U.S. coal ...

A major component of U.S. coal production, subbituminous coal makes up 47% of U.S. coal production by weight and 41% by energy intensity. Although subbituminous coal has the second lowest energy content, large quantities are found in thick beds near the surface, resulting in low mining cost and, correspondingly, lower prices.

coal | National Geographic Society

Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
