As coal is removed from one section of a surface mine, the land at another part is returned, regraded and replanted so it will be as good as or better than it was before mining began. This process is called reclamation. Because of it, modern surface mining is a temporary land use, involving not just excavation or extraction of the coal, but ...

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 if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.
