COAL - OPEN-CAST COAL MINING
A 300 million year old coal-seam just 18' (0.5m thick) is excavated
at the surface by mechanical equipment. This seam would have been
too thin to have been economically mined in an underground operation.
The coal seams are the remains of lush tropical-rain-forest type.
Coal has a much higher heat content than Peat (see images B4 & B5). It is much older than Peat and has been compressed so it much
harder and more like rock.
