HOW WE MINE COAL In the United States, coal is currently mined in 25 states, primarily by using either surface mining techniques or underground methods. Surface mining accounts for about 60 percent of the coal produced in the United States. It is used mostly in the West where huge coal deposits lie near the surface and can be up to 100 feet thick.
