Coal - Wikipedia
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is 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. 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 (Pennsy

Coal is a black sedimentary rock. It usually occurs in coal beds found in coal mines. Coal comprises of carbon, hydrogen, oxygen, sulphur, etc. When dead plants and animals decay and convert into peat which in turn is converted into lignite, then sub-bituminous coal, after that bituminous coal, and lastly anthracite. Hence, coal is a fossil fuel.

Sep 03, 2010 Most coal production in South Africa - about 53% - is from opencast mines, with the balance being produced by bord-and-pillar (40%), stoping (4%) and longwall mining (3%). Coal mining operations are clustered in the country's Mpumalanga province, accounting for over 84% of South Africa's coal production. The remaining output comes from the Limpopo province's two operating mines -
