Abstract: | Based on experiment results and theoretical analysis, pointed out that the method of coal susceptibility to spontaneous combustion
determination with fluid oxygen adsorption can not present the essence of coal oxidation process and oxidation reaction. The
method is incorrect, paying attention at one aspect and ignoring the rest. The method is not reasonable for coal susceptibility
to spontaneous combustion determination. Susceptibility to spontaneous combustion of coal reflects chemical property of coal
oxidation with oxygen absorption and heat release at low temperature. Coal’s susceptibility to spontaneous combustion is mainly
decided by the number of molecules with reaction activation energy and activation molecule production rate at certain temperature.
Therefore, index of susceptibility to spontaneous combustion should adopt accumulative value or trend of heat release or oxygen
adsorption during oxidation process.
