Our main source of coal comes from a coal mine near Butler, Missouri. A stock pile of coal for unexpected emergencies is maintained at Blue Valley. A 90-day supply of coal consists of 45,000 tons of coal. Coal Feeders Feeding coal from the bunkers to the pulverizers is the purpose of the coal feeders. The pulverizers grind the coal into a fine .

Coal deposits are mined by cutting a network of 'roads' into the coal seam & leaving behind 'pillars' of coal to support the roof of the mine. These pillars can be up to 40% of the total coal in the seam - although this coal can sometimes be recovered at a later stage by 'retreat mining'.The roof is then allowed to collapse and the mine is

In 2005, Illinois ranked ninth nation-wide in coal production, and the state’s annual total coal production was about 32 million tons (www.eia.doe.gov). Illinois is first in the nation for reserves of bituminous coal, the country’s most widely used coal rank (Illinois Depart-ment of Mines and Minerals
