Abstract
Aiming at the characteristic of airflow fluctuating in mine, based on the theory of mine ventilation, the theory of fluid mechanics, the theory of aerodynamics, the theory of mass and heat transfer, and the theory of infiltration flow through porous media, mathematical model about airflow fluctuating in mine is established；distribution features of flow field in goaf under the airflow fluctuating are researched by numerical simulation, and the model is reset and tested by corresponding experiment. The results show: mathematical model establi shed about airflow fluctuating in mine can be used for researching dist ribution of flow field in goaf,and can provide an effective method to fire preve ntion and treatment in goaf.
