| In this thesis, by the means of adiabatic oxidation test of coal samples, the kinetic essentials of coal low-temperature oxidation in spontaneous combustion process are analyzed and the reaction kinetic model is developed. Temperature and oxygen concentration are the two main token macro-parameters relating to spontaneous combustion, the change rule and the relationship between them and their influence factors are dealt with. Finally, the temperature field mathematical model and oxygen-diffusing field mathematical model in coal low temperature oxidation process are put forward under approximately adiabatic surrounding conditions.
