Waterproof role of fire and explosion isolation doors

Fire, flood and explosion is a significant threat to the safety of the mine disaster , waterproof fire -proof doors are controlled isolation scope of these major disasters, the most important means , but the isolation doors closed will change mine ventilation system , to change the main fan operating point , may cause localized  power transformers breeze or no wind , gas gauge , main fan surge issues such as isolation gate position in the design of mine when the resulting security risks must be fully considered in order to protect isolated gate enabled the mine ventilation system security. Waterproof role of fire and explosion isolation  Air circuit breaker the mine threat in a panel adjacent to the panel and the whole mine fires, floods, explosions of major disasters , in order to prevent the accident and reduce the life of these major disasters , loss of property , accident closed  mcb circuit breaker  fire and explosion isolation doors , protecting the mine area and the other disk into the return air main roadway , wellbore safety and to avoid disasters expanding spread. Isolated door panel settings are mine happen water, fire , explosions and other major disasters of the last mine safety barrier is to ensure mine safety emergency last line of defense , so the isolated gate setting has important practical significance.
