The Research on the Relationship between the Coal Volatile and the Kinetics Parameters by Thermo-Gravimetric Experiment

Abstract:

Coal spontaneous combustion is a common coal mine disaster, the internal mechanism of coal combustion is revealed better by researched the relationship between the coal volatile and the kinetics parameters. Based on the method of non-isothermal, the coal samples from Jinggezhuang9#, Jinggezhuang11#, Qianjiaying, Tangshan and Tunlan are used the thermo-gravimetric experiment. The relationship between the reactive kinetic parameter and the volatile matter are fond out, when the heating rate is 100C/min. The experiment results illustrate that the more the volatile matter is, the less the activation energy (E) and the Pre Exponential factor (A) are, and the difficulty rank of coal samples of spontaneous combustion is Jinggezhuang9#, Jinggezhuang11#, Tangshan, Qianjiaying, Tunlan.
