    Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

    Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a pit, and the above-ground structures are a pit head.

    After coal is mined, is it ready to be shipped. If the mine is close to a destination, trucks can carry the load. Using conveyors to move coal is another option for shorter distances. In 68 percent of cases, coal is transported by the railroad. This can be very expensive. Sometimes the cost of shipping coal by train is more than the mining costs.

    The history of coal mining goes back thousands of years. 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. Compared to wood fuels, coal yields a higher amount of energy per mass and can often be obtained in areas where wood is not readily available. Though it was used historically as a domestic fuel, coal is now used mostly in indu
