The self-heating properties of 3 dried coals were measured using the adiabatic tester at a temperature range of about 40~100°C and the concentrations of CO and CO2 gas generated from the coals were analyzed simultaneously. The adiabatic self-heating test results showed that the temperature increase rate was higher as the O/C of coal was higher. The gas analysis showed that the higher the self-heating rate, CO and CO2 generation rates was higher. Moreover, it was found the rates of the temperature increase were correlated with CO generation rates and there was small difference in coals in terms of total amount of CO and CO2 generated from 40°C to any temperature.
