Abstract :
Through dimensionless analysis on effect factors of spontaneous combustion in goaf, this paper establishes a coupling mathematical model including skeleton temperature field, air temperature field, velocity field and oxygen concentration field to reveal the characteristics of spontaneous combustion. A visual graphic program is also developed to calculate and simulate the oxygen concentration and speed. The research results provide a theoretical basis for understanding the real situation and preventing spontaneous combustion in goaf.
