  • What is coal & where is it found? | World Coal Association

    Coal is a fossil fuel, formed from vegetation, which has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago. Types of coal.

  • Coal Mining

    Coal Mining. Types of Coal Mines. There are four main types of coal mines: shaft mine, slope mine, drift mine, and surface (open-cast) mine. The mine at Coalwood was a shaft mine; the coal was brought up in an elevator from 600 to 800 feet underground. The University of Kentucky has an interesting diagram showing each of the four types of mining.

The four ranks are: Anthracite: The highest rank of coal.

  • Glossary of Mining Terms

    A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
