摘　　要：针对大采高特厚易燃煤层综放开采时的防灭火问题,结合矿井实际生产条件和煤层自然氧化程度,设计了矿井采空区综合防灭火方案,加强监测监控,减少采空区遗煤,提高支护质量,充填裂隙,加强密闭,减少漏风,并利用氮气和复合胶体进行防灭火的治理。通过现场效果验证该措施有效地防止工作面采空区的自燃发火,保障了矿井安全生产。In light of fire prevention ＆ control problems during fully-mechanized mining at ultra thick flammable seam, in combination with actual production conditions and the oxidation degree of coal mine, a goaf comprehensive fire prevention and control plan is designed to strengthen monitoring and control, reduce coal remaining coal at goaf, improve supporting quality, fill the fracture, enhance sealing and re-duce air leakage, and proceed with fire prevention and treatment by use of nitrogen and composite colloid. Through on-site effect verification, these measures could effectively prevent spontaneous combustion in goaf so as to ensure safety production of coal mine.
