    Where is Coal Found? | Sciencing

    Apr 24, 2017· Some coal beds lie within 200 feet of the earth's surface. These beds are mined by stripping the top soil off the coal. Then the coal is dug out. This is called surface mining. Deeper coal beds can be found up to one thousand feet below the earth. Miners tunnel underground to get this coal. This is the most dangerous kind of coal mining.
