Coal

In underground mining, workers and machinery go down a vertical "shaft" or a slanted tunnel called a "slope" to remove the coal. Mine shafts may sink as much as 1,000 feet deep. One underground mining method is called room-and-pillar mining. With this method, much of the coal must be left behind to support the mine''s roofs and walls.
