摘　　要：针对高瓦斯特厚易燃煤层在大采高综放开采时采空区瓦斯抽采与防灭火相矛盾的问题,结合矿井实际生产条件和煤层自然氧化程度,采用了采空区调压控氧防灭火技术,同时加强监测监控和调节管理,可以有效减少漏风,防止工作面采空区自燃发火,保障矿井安全生产。Problems of Gas extraction and fire Prevention occur at goaf during large height fully-mechanized mining of high gas extra thick flammable coal seam. In combination with coal mine＇s actual production conditions and the natural oxidation degree, goaf pressure regulation and oxygen control fire prevention technology is used. Strengthening monitoring and regulation management can effectively reduce leakage and prevent spontaneous combustion in goaf, so as to protect production safety of the coal mine.
