Abstract
In order to optimize underground ventilation system, the tracer gas experiment was carried out to analysis airflow characteristics. Then, numerical simulation was applied for ventilation system to evaluate the airflow transfer and diffusion law. After that, the paper investigated air velocity and dispersion coefficient relationship on basis of measured and simulated data comparison. The disadvantages existing in current ventilation system were identified. It was proved that the method used in this paper is effective which provides theoretic bases for optimizing underground mine ventilation system.
