Both openings serve to circulate air in the mine. Coal is then broken up and mined by one of several methods: Conventional mining – The older practice of using explosives to break up a coal seam. Continuous mining – A huge machine with a large rotating steel drum equipped with tungsten carbide teeth scrapes coal from a seam at high speeds.
Coal density and compositional properties are not uniform throughout the coal seam but vary vertically and laterally as a function of coal rank, moisture content, and mineral matter content, among other depositional environment geological variables.

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. 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.
