Coal that is surfacemined is usually found in seams that range in size from 2 feet ( meter) to more than 100 feet (30 meters) thick. Some seams contain as much as 200,000 tons of coal in a single acre ( hectare). Normally, between 90 and 100 percent of this coal is recovered during surface mining operations.

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.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...

THE FORMATION OF COAL What is Coal? Coal is a combustible, sedimentary, organic rock formed from ancient vegetation, which has been consolidated between other rock strata and transformed by the combined effects of microbial action, pressure and heat over a considerable time. This process is referred to as 'coalification'.
