Coal is a type of fossil fuel, formed when dead plant matter decays into peat which is converted into coal by the heat and pressure of deep burial over millions of years. [2] Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian ...
Coal River was the first name given by British settlers to the Hunter River after coal was found there in 1795. In 1804 the Sydney-based administration established a permanent convict settlement near the mouth of the Hunter River to mine and load the coal, predetermining the town's future as a coal port by naming it Newcastle.
The history of coal mining in the United States starts with the first commercial use in 1701, within the Manakin-Sabot area of Richmond, Virginia. [1] Coal was the dominant power source in the late 1800s and early 1900s, and although in rapid decline it remains a significant source of energy in 2024.
Coal mining is the process of extracting coal from the ground or from a mine. 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.
The name Carboniferous means "coal-bearing", from the Latin carbō ("coal") and ferō ("bear, carry"), and refers to the many coal beds formed globally during that time. [8] The first of the modern "system" names, it was coined by geologists William Conybeare and William Phillips in 1822, [9] based on a study of the British rock succession.

The Appalachian Basin is one of the most important coal producing regions in the U.S. and one of the largest in the world. Bituminous coal has been mined throughout the last three centuries. Currently, the coal primarily is used within the eastern U.S. or exported for electrical power generation, but some of it is suitable for metallurgical ...
