To clarify the reaction between water and coal for the purpose of elucidating the coal spontaneous exothermic phenomenon, experiments were conducted using H217O. Coal and H217O were treated at 40-80°C in an O2 atmosphere. The gases generated were quantified by a high-resolution mass spectrometer. The results showed that about half of the CO and CO2 generated contained 17O even at the low temperature of 40°C, suggesting that the influence of chemical reaction with water in the coal spontaneous exothermic phenomenon is significant.
