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。
針對大採高特厚易燃煤層綜放開採時的防滅火問題，結閤礦井實際生產條件和煤層自然氧化程度，設計瞭礦井採空區綜閤防滅火方案，加彊鑑測鑑控，減少採空區遺煤，提高支護質量，充填裂隙，加彊密閉，減少漏風，併利用氮氣和複閤膠體進行防滅火的治理。通過現場效果驗證該措施有效地防止工作麵採空區的自燃髮火，保障瞭礦井安全生產。

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.
