Simulation on Distribution of Oxygen Concentration in Mining Goaf
The coupling mathematical model is established including velocity field, oxygen concentration field and temperature field in goaf according to the theory of Finite Volume Method (FVM) and the flowing field safety theory to reveal the characteristics of spontaneous combustion. Whats more, the moving coordinates is introduced based on the character of the moving workface, so the visual graphic program is also developed to calculate and simulate the velocity field, the oxygen concentration distribution in goaf by VB program and tecplot software. The simulation result is satisfied with the fact of goaf. At the same time, the program can describe distinctly the dynamic change situation and the influence of various conditions on spontaneous combustion in goaf. And the result can provide the detailed data information and the theoretical basis for preventing from spontaneous combustion in goaf.
