There are two types of coal mines, surface and underground, currently producing coal in Colorado. A surface mine removes coal from excavated surface pits. The mining sequence includes vegetation removal, topsoil removal and storage, overburden removal, and coal extraction. After coal is removed, open pits are backfilled and regraded to approximate original contour, topsoil
Pillars refer to the pillars of coal that are left in place to help support the ceiling. Using this method of mining may reduce the coal extraction ratio up to 60%. In Alaska underground mining was the primary form of coal mining used until about the late 1930's – early 1940's ( I was unable to find an exact date.)
Coal is produced from underground mines using longwall or roomandpillar mining technology. Longwall mining consists of developing the coal in rectangular blocks called "panels," using roomandpillar mining equipment. Longwall panels are developed to maximize the recovery of coal and are up to 900 feet wide by 10,000 feet long.
