More than twothirds of coal extracted underground is done by a quot;continuous miner,quot; a tractor with a mounted cylindrical grinder that breaks coal away from the seam. The continuous miner deliberately leaves undisturbed pillars of rock and coal in the mining area to create natural supports for the ceiling. This is known as quot;room and pillarquot; mining.

Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many coal beds are very near the grounds surface, and about twothirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves.
The history of coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today
