惰性阻化泡沫技术防治采空区自然发火研究

Study on Preventing Spontaneous Combustion in Goaf by Inert Inhibitor Foam Technology

针对阳城煤矿3306综放工作面回采期间采空区漏风造成工作面CO浓度超限问题,研究应用了惰性阻化泡沫防火技术。该技术利用惰性阻化泡沫的渗透、堆积和扩散特性,达到对防火区域惰化、堵漏、窒息、阻爆灭火等目的。这技术在3306工作面防治采空区自然发火获得了成功应用,确保了工作面安全回采。

In view of the problem of CO concentration exceeding the working face caused by air leakage in goaf during the mining of 3306 fully mechanized caving face in Yangcheng Coal Mine,inert retarding foam fire prevention technology is researched and applied.The technology uses inert blocking foam’s infiltration,accumulation and diffusion characteristics to achieve inert,plugging,asphyxiation,and detonation suppression for fire prevention area.This technology has been successfully applied in 3306 working face to prevent spontaneous combustion in goaf and ensure safe mining.
