Coal-bed methane potential of
Carboniferous coals (Westphalian A-C) from three
major onshore basins (Cumberland, Stellarton, and
Sydney) has been evaluated in relation to both the geological framework and
physical or chemical properties of major coal seams. The current data suggests
that coal composition, maturation and structural stress have a close
relationship with the production characteristics, adsorption properties and the
porosity or permeability of various coal seams.
The production data from the major coal
seams from these three suggests that 5-20 cm3 of methane per gram of coal could
be produced. The higher gas content is mainly concentrated within the
