COAL - OPEN-CAST COAL MINIG. NOTTINGHAMSHIRE, UK
COAL seams from the Carboniferous/Pennsylvanian (Upper Palaeozoic)
era. The remains of lush tropical-rain-forest type vegetation
preserved from 300 million plus years ago. A coal-seam just 18'
(0.5m thick) is excavated at the surface by mechanical equipment.
This seam would have been too thin top have been economically
mined in an underground operation.
Coal has a much higher Carbon and lower volatile content than
Peat (see images B4 & B5). It is much older than Peat and has been compressed by an over-burden
of, in some cases, a great thickness of rock.
