摘　　要：分析了峻德煤矿综放工作面近距离采空区隐蔽火源的特点与治理难点,介绍了三相泡沫的组成与特点,详细阐述了应用三相泡沫成功治理综采二队综放工作面自燃火灾的过程。实践表明:通过将三相泡沫大流量短时间内注入可能发火区域,能快速捕捉到高温点并迅速降温、熄灭火源;同时,含N2三相泡沫具有惰化、抑爆作用,尤其适合煤与瓦斯共存条件下的火区治理。This paper analyzed the features and control difficulty of concealed fire source in the short -distance gob of a fully mechanized working face in Junde Coal Mine, described the composition and property of three-phase foam and gave a minute description of the process of successfully applying three -phase foam to extingush the spontaneous fire in a fully mechanized working face of the mine. The practice showed that the injection of large amount of three-phase foam into a possible fire area in a short time can rapidly catch the high-temperature point, cool and extinguish the fire source. Three-phase foam containing N2 also has the function of inertial and explosion suppression, so it is especially suitable for the control of fire under the condition of coexistence of coal and gas.
