Types And Classification Of Coal Mining For Schools

Within the broad classification of bituminous coal there are several sub classifications based on volatile content and these are • Low volatile bituminous coal with 22 volatiles on a dry ash free basis • Medium volatile bituminous coal with volatiles between 22 and 31 • High volatile bituminous coal with volatile content of 31.Coals from oil and gas wells in the Gippsland Basin (Victoria Australia) and in the Taranaki Basin (New Zealand) range up to high volatile bituminous in rank and exhibit a wide range of coal type Original depths of burial are estimated at up.
