Article defines mathematical model of the low-temperature oxidation of bituminous coal. The mathematical model defines single phase mathematical model with porous zone as coal where consumption of oxygen, production of smoke exhaust and heat are solved as source terms in transport equations. Result of numerical calculation is compared with experimental measuring. The rate constant defines by Arrhenius expression. For numerical calculation method of finite volume (software ANSYS FLUENT 12) was used.
