contact usThe coal seams are generally filled with water and it is the pressure of the water that keeps the gas as a thin film on the surface of the coal. The technical term for this is ''adsorption''. Natural gas in coal seams in Australia is not a new discovery. It was first identified when coal mining began in the early 1900s.
