Abstract：The relationships between determination time and ‘inherent volatile matter’ of Xinjiang middling, steam coal and washing gangue were discussed.The results indicated that ‘inherent volatile matter’ increased with the increase of heating time and became stable when coal sample was heated to a certain duration (100 min); coal sample could not accurately describe CRC value when it was heated more than 60 min in the absence of air.Determination according to standardcould not reflect the true' inherent volatile matter', determination of'inherent volatile matter'of different coal speciesshould be researched further.
