Emergency control technology of air and smoke flow in mine belt roadway fire based on Ventsim software

Meikuang Anquan, 2022
Mine belt fires are prone to cause heavy casualties due to their strong suddenness and difficulty in disaster relief and fire fighting. Quick and effective wind control, smoke exhaust, and evacuation are the keys to disaster relief.
