在矿山救护工作的实践中,解决遥控扑灭井下火灾的最有前途的方向之一是使用惰性气体。这种扑灭火灾方法是要在出事的巷道内形成一种使燃烧不能继续下去的介质,快速扑灭燃烧的火焰,并防止火区可燃气体积聚时引起爆炸。在矿山救护队的实际工作中,主要采用二氧化碳、氮和蒸汽混合气体作为惰性气体。二氧化碳的使用。为了扑灭火灾并同时防止可燃气体与空气混合而引起爆炸,在使用二氧化碳时必须使氧的含量减少到13.5%
In the practice of mine rescue work, one of the most promising directions to solve the remote fire suppression underground fire is the use of inert gas. This method of extinguishing a fire is to create a medium in the roadway where the accident can not continue the combustion, quickly extinguish the burning flame and prevent explosion when the combustible gas in the fire area accumulates. In the actual work of the mine rescue team, the main use of carbon dioxide, nitrogen and steam mixed gas as an inert gas. Use of carbon dioxide. In order to extinguish a fire and at the same time prevent the combustible gas from mixing with the air and causing an explosion, the oxygen content must be reduced to 13.5% when using carbon dioxide
