| Abstract: | The kernel of studying on coal spontaneous combustion is researching its spontaneous combustion mechanism.Based on coal oxygen complex action theory,this paper has set up the dynamics mathematical model of reaction between coal and oxygen. By means of the mathematical model,and combined with the experimental datum,a series of dynamics parameters of reaction between coal and oxygen in the progress of temperature rising can be calculated.From the calculating example, it indicated that the calculating parameters can entirely reflect the features of reaction between coal and oxygen. This method provides a feasible technical approach to explore the mechanism of coal spontaneous combustion and how to estimate the fatalness of coal spontaneous combustion. 3tabs.,6refs. |
