Abstract

This paper started with the theory of surrounding rock and the air heat exchange, analyzed the principle and process of natural wind pressure. GAMBIT software was used to establish the main ventilation shaft model and fluid software FLUENT was used for a numerical simulation on air flow and heat transfer. By changing the boundary conditions of the model, we obtained multiple sets of natural wind pressure data. Finally, used MINITAB curve fitting method to fit the data, we obtained formulas of natural wind pressure.
