对2320隐蔽老火区首先通过灌注泥浆对火区进行治理，同时对部分裂隙通道进行堵漏，然后对泥浆不能到达的区域注入高倍数三相泡沫灭火材料泡沫，瞬间将火源处覆盖，火源因隔绝氧气而窒息灭火。三相泡沫具有良好的堆积性和流动性，对煤体具有保水保湿，惰化遗煤氧化空间，并能够对松散煤体进行化学阻化，从本质上降低遗煤自然氧化速率，消灭了隐蔽老火区的火灾隐患，具有较高的推广价值。

By comprehensive management of stereo type combination using grouting, injection of three-phase foam ifre extinguishing technology means in 2320 old and hidden ifre district, ifrst pouring the mud to govern the ifre area, at the same time plugging on the part of the fracture passage, and then injecting the high multiples of three phase foam ifre extinguishing foam into the ifre area which the mud can’t reach, will cover the moment, isolate oxygen and smothering. Three phase foam has good accumulation and mobility, has water moisture of coal body, inerting coal oxidation lost in space, and can carry on the chemical resistance of loose coal, thereby substantially reduce the residual coal natural oxidation rate, eliminate ifre hidden troubles hidden old area, has high value of popularization.
