Coal comes in three main types or grades. First, the swampy peat is squeezed and heated to form brown, soft coal called lignite. In the process, the material releases hydrocarbons, which migrate away and eventually become petroleum. With more heat and pressure lignite releases more hydrocarbons and becomes the highergrade bituminous coal ...
Beneath much of Illinois lies a black treasure—coal. Illinois coal deposits began to form more than 300 million years ago during the Pennsylvanian Period, when the land that is now Illinois was near the equator. In a succession of dense, tropical swamps, the ancestors of modern ferns and scouring rushes grew as tall as trees, while dragonflies with wingspans of up to 2 feet droned over the ...

Many coal beds are very near the ground''s surface, and about twothirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves. Due to growth in surface mining and improved mining technology, the amount of coal produced by one miner in one hour has more than tripled since 1978.

The coal we burn today got its start some 300 million years ago. Back then, dinosaurs roamed the Earth. But they didn''t get incorporated into coal. Instead, plants in bogs and swamps died. As this greenery sunk to the bottom of those wet areas, it partially decayed and turned into peat. Those wetlands dried out.
