What we mine & why we mine - NSW Mining

Coal is a combustible rock made mainly of carbon, hydrogen and oxygen. Coal is formed when accumulated plant material is buried, decays and is exposed to heat and pressure over millions of years. Layers of coal are interspersed with other sedimentary material, like shale and sandstone, to form coal beds or seams which range in size from less than one millimetre to several metres thick.
