Numerical Simulation of Gas Accumulation Condition in Contact Tunnel Between Parallel Roadways

A simplified physical model of air flow in contact tunnel (basic symmetrical angle-linking) between parallel roadways is established based on Yameidaning's production instance. According to the mathematical equations of the airflow movement in contact tunnel, the fluent software is used to simulate the airflow rule in contacting tunnel and study the conditions of the gas accumulation in contact tunnel.
