Studies of coal -rich regularity in coal -bearing basin is the focus of coal geology. The excellent development of coal - rich regularity in recent decades includes mainly coal - bearing model, coal -rich belt and coal - rich unit, comparative sedimentology of modern peat and swamp. Especially in re cent, studies of coal - rich unit and comparative sedimentology of modern peat and swamp reveal clear ly the relationship of coal distribution and genetic coal petrography or industrial coal petrogra phy. Hence,these result provide a helpful method for predicting good quality coal in coal-bearing basin.
