摘　　要：深井易自燃厚煤层综放工作面自然发火重大风险在长期停工状态下管理难度加大,稍有不慎可发展成自燃隐患,甚至火灾事故。本文通过3306综放工作面采用快速封闭注氮、均压技术降低漏风、监测分析等综合措施杜绝了火灾隐患。The spontaneous combustion risk of fully mechanized top coal caving face in deep spontaneous combustion thick coal seam is great.Under the condition of long-term shutdown,the management is more difficult,and slight carelessness can develop into spontaneous combustion hidden danger,even fire accident.In this paper,the 3306 fully mechanized top coal caving face using rapid closed nitrogen injection,pressure balancing technology to reduce air leakage,monitoring analysis and other comprehensive measures to eliminate fire hazards.
