  • Coal Geology Geoscience Australia

    Coal is mined by both surface or 'opencut' (or opencast) and underground or 'deep' mining methods, depending on the local geology of the deposit. Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia's coal is produced from opencut mines. Opencut mining is only economic when the coal seam(s) is near the sur face. It

  • Coal mining Wikipedia

    Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity.

  • Greenhouse gases generated in underground coalmine fires

    The release of greenhouse gases from underground coalmine fires is a function of temperature and the concentration of O 2. In a laboratory study on spontaneous combustion, samples of coal, coal refuse, and carbonaceous shale were heated at a controlled rate between ambient temperature and 250 °C.

  • Coal Geology and Geochemistry Encyclopedia of Life

    For extracting coal from underground, the scope of coal seams, the reserves of coal, and the geological structure of the coalfield must be known. Coal exploration can provide such information. Recently, because of findings relating to hydrocarbons in coal, and pollution from coal mining and coal utilization, many achievements have been made in the field of coal geochemistry. One example is the

    The coal can then be removed without the coal miners having to go deep underground. Underground mining is when the coal is farther underground, making it too expensive to remove soil. In this process, coal miners and all of the coal mining equipment are brought deep underground and coal is carried up out of the ground.

    Coal is a combustible black or brownishblack 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.
