Most of the coal burned in US power plants is bituminous or subbituminous coal. A fifth type, called metallurgical (or "coking") coal, is used for steelmaking. All types of coal also contain sulfur, which, when burned, releases toxic air pollution. Sulfur content is determined by the conditions under which the coal is formed.

Coal miners use two primary methods to remove coal. Surface mining is often used when coal is less than 200 feet underground. In surface mining, large machines remove the topsoil and layers of rock known as overburden to expose coal seams. Mountaintop removal is a form of surface mining where the tops of mountains are removed to access coal seams.

This process is called carbonization. So, carbonization can be defined as the slow process in which the dead plants and trees under the surface of the earth in high pressure and temperature form coal. It is called fossil fuels because it is formed by the dead remains of plants. So, when coal is heated it forms carbon dioxide and heat energy.
