矿山巷道中发生的火灾,将会急剧扩大,不仅对巷道中的设备,对作业人员也会带来很大的灾害,进而酿成重大灾害。作为控制这种巷道火灾蔓延的方法,目前决定根据防蔓延设施的设置管理指南(耐火带和水喷雾带),以图控制蔓延的方法用于现场。 控制巷道火灾蔓延的方法之一是采用控制通风的方式。对原来的防火灾措施来说,火灾发生时通风变化不明确,而且很难撑握通风系统,所以几乎没有撑握住控制通风的方法。然而,到目前从火灾时的通风特性实验研究和通过变化摸拟研究的结果看,即使变化通风条件,在某种程度上也有可能对通风系统进行解析。因此,作为今后控制火灾的一个手段就是 The fire in the roadway of the mine will expand rapidly. Not only the equipment in the roadway but also the workers will bring great disaster, which will lead to a serious disaster. As a method of controlling the spread of this kind of roadway fire, it is currently decided to use the method of spread control in the field in accordance with the guide for setting management of anti-spread facilities (refractory belts and water spray belts). One way to control the spread of a roadway fire is to use controlled ventilation. For the original fire prevention measures, the change of ventilation during the fire was not clear, and it was difficult to hold the ventilation system, so there was almost no way of holding the control ventilation. However, up to now, the experimental study of the ventilation characteristics at the time of fire and the result of the simulation study of the change show that it is possible to analyze the ventilation system to some extent even if the ventilation conditions are changed. Therefore, as a means of controlling fire in the future
