Mining giant Adani has shrugged off accusations it exaggerated the number of jobs its massive Queensland coal mine would produce.

Environmental organisation Coast and Country seized on revelations in court on Monday the Carmichael mega-mine in the Galilee Basin would create an average of 1464 jobs per year, not the 10,000 jobs figure more commonly associated with the project.

The organisation is looking to block the mine in the Land Court of Australia, represented by lawyers from the Environmental Defenders Office Queensland.

Coast and Country spokesman Derec Davies accused the Indian mining giant of misrepresenting the numbers.
