Aug 14, 2020· Why is Coal Valuable? Coal is a fossil fuel formed from dead plant matter trapped between rock deposits. Over a period of millions of years, biological and geological processes turn this material into peat and then through further metamorphosis into lignite, sub-bituminous coal and finally anthracite coal.. Coal has been used as an energy source throughout human history.

Coal Mining Methods - Colorado School of Mines

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.
