But if we want to understand the origins of coal, we have to look back much further — to a period called the Carboniferous.The Carboniferous (after the Latin name of coal) took place approximately 360 to 300 million years ago.

  • Coal formation - Energy Education

    Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbon-based material - approximately 50% of its weight. The formation of coal takes a significant amount of time (on the order of a few million years), and the first coal-bearing rock units appeared about 290-360 million years ago, at a time known as the Carboniferous or "coal-bearing" Period.

    Most underground coal is mined by the room and pillar method, where by rooms are cut into the coal bed leaving a series of pillars, or columns of coal, to help support the mine roof and control the flow of air.Generally, rooms are 2,000 feet wide and the pillars up to 300 feet wide. At least 60 feet of coal was left between an underground mine and the surface, if not the surface had a higher ...

  • How is Coal Formed? - Definition, Mining Uses with Videos

    The formation of coal takes millions of years, which is why it is an exhaustible and non-renewable natural resource. It was formed around 300 million years ago when the earth was covered with swampy forests. When plants in these forests- mainly trees, mosses, ferns, and reeds died, they fell into the swamps. Thus there was a thick layer of dead vegetation in the swamp formed. As years passed ...

  • What are the different types of coal? American ...

    The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or “ranks,” of coal are determined by carbon content.

    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 or better than it was before mining began. This process is called reclamation and because of it, modern surface mining is a temporary land use, involving not just excavation and extraction of coal, but also restoration and return of the land to productive use.
