Coal mining - Coal preparation Britannica

As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions. In addition, during the process of mining , a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners.

Formation of Coal - Definition, Uses Fossil Fuels

Coal is fossil fuel or fuel that comes from the remains of prehistoric plants or animals. The formation of coal occurs over millions of years via a process known as carbonation. In this process, dead vegetation is converted into carbon-rich coal under very high temperature and pressure. Minerals and energy play a very important role in the ...
