Although longwall mining is used virtually exclusively to produce coal from un-derground mines in Europe, it accounts for only 5 percent of annual underground coal production in the United States. Longwall sys-tems have been used in several European countries to extract most of the reserves in 30-ft thick seams at depths of 3,000 ft ...
Read MoreThe process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: A machine called a pulverizer grinds the coal into a fine powder. The coal powder mixes with hot air, which helps the coal burn more efficiently, and the mixture moves to the furnace.
