  • Coal mining and transportationU.S. Energy Information

     · Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits called coal beds or seams are near the earth s surface while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation s coal reserves and to produce about three times more coal in one hour than in 1978.

  • How much CO2 and pollution comes from burning coal

     · 122 pounds of coal ash is left over. Coal ash is the solid byproduct left over after coal is burned. It is second only to trash as the largest source of waste material in the US. According to the EPA and the American Coal Ash Association coal power plants created just under 130 million tons of ash in 2014.This means that every ton of coal we burn leaves 122 pounds of coal ash.
