为予防煤尘爆炸,生产矿井必须经常注意清除堆积煤尘、消除火源,同时为制止予料不到的煤尘爆炸传播,需要布设岩粉棚、水棚、浓度岩粉地带及水喷雾地巷等这些所谓予防爆炸传播的设置.上述的这种基本设置,还有个爆炸火焰温度问题.如判断水棚、水袋制止传播然烧的效果时,为使飞散水滴吸收火焰热量的机能卓有成效,以火焰产生的总热量、火焰温度具有的程度作为计算基础.
In order to prevent coal dust explosion, mine production must always pay attention to clear the accumulation of coal dust, eliminate the source of fire, and to prevent the spread of coal dust to unpredictable distribution, the need to set up rock powder shed, water shed, concentration rock powder and water spray Lane, etc. These so-called explosion-proof set to spread the above basic set, there is a blast flame temperature issues such as judging the water shed, water bag to stop the spread of the effect of burning, in order to make the scattering of water droplets to absorb the heat of the flame effect , To the total heat generated by the flame, the flame temperature has the degree as a basis for calculation.
