苏联科学院矿业研究所东方分所对利用空气泡沫预防和扑灭内因火灾新的工艺设备和方法进行了研究。泡沫灭火工艺系统用的主要装备是 УЛЭП—2型内因火灾灭火器。该灭火装置是为了预防和扑灭煤层采空区和巷道高旋顶的自然发火。将制备的泡沫注入冒落的岩石里以灭火。要有清洁的水和压缩空气是使用泡沫的两个必需条件。此时无论是用井下消防火的管道水,还是用水泵
Eastern Institute of Mining Research Institute of the Soviet Academy of Sciences on the use of air bubbles to prevent and extinguish the internal combustion of new technological equipment and methods were studied. Foam fire extinguishing system is the main equipment used УЛЭП-2 type fire extinction. The fire extinguishing device is to prevent and extinguish the spontaneous combustion of the coal top mined-out area and the tunnel high-rotation top. The prepared foam is poured into the rock for fire to extinguish the fire. Having clean water and compressed air are two of the essentials for using foam. At this point whether it is downhole fire fire water pipes, or water pump
