易自燃厚煤层综放工作面采空区自燃灭火技术

Spontaneous Combustion Fire-fighting Technology for Thick Seam at Full-mechanized Mining Face in Gob

针对综放工作面采空区自燃发火,采取了在运输巷、工作面开钻场、打钻孔注浆、注胶,封堵上、下隅角盲巷,注氮气、注三相泡沫,调节工作面风量等综合灭火技术,成功地扑灭了综放工作面采空区自燃发火,实现了矿井安全生产。

Direct to the gob spontaneous combustion at fully mechanized face, takes the fire fighting integrated technology of drilling at haulage road and face grouting with hole inject glue, sealing the upper and lower corner blind alley, injecting nitrogen, injecting threephase foam, regulating the amount of face wind, success fuly fight against the gob spontaneous combustion at fully mechanized face and realized the mine safe production.
