Popis: Basing on coal and the oxygen evolving complex theory, the method of study on the spontaneous combustion by analysis the microporous in coal has been established in this article. By the electron microscope, the process of microporous volume changeing with the temperature gradually increased is observed. It is believe that the process of spontaneous combustion reaction should be carried out in the microporous. Finally, under the help with finite element analysis , the temperature field surrounding microporous has been analyzed and the distribution regularity of the temperature field has been obtain. It make the conclusion that coal surface microporous can be used as evidence of coal spontaneous combustion reaction.
