Do we have to dig deep to find coal?

    Coal can be extracted both through surface mining and deep mining. Surface mining refers to coal buried less than 200 feet, and is how most U.S. coal is extracted. This process uses heavy equipment to remove the top-soil and expose coal beds. Underground or deep mining deposits can be as much as 1,000 feet deep and require mine shafts and elevators.
