在分析龙固矿N1301综放面调向期间煤层自燃特点的基础上,提出了综放面调向期间的自燃监测及预防技术方案,建立了以“阻化、惰化、降温”为一体的综合防灭火技术体系,分别采用注氮惰化为注、注黄泥复胶体封堵降温阻化相结合的防灭火技术措施。这些技术的成功运用为预防调向期间采空区遗煤的自燃,保障综放面的安全生产创造了条件。
Based on the analysis of the characteristics of spontaneous combustion in the direction of the Longguang N1301 fully mechanized top-coal caving mining face, the paper presents the technical scheme of spontaneous combustion monitoring and prevention during the period of fully mechanized top - coal caving, and established the method of “resistance, inerting and cooling” One integrated fire-fighting technology system, respectively, injection of nitrogen inerting Note, Note yellow mud seal cooling resistance combination of fire prevention and control measures. The successful application of these technologies has created the conditions for preventing spontaneous combustion of coal left in the goaf during the period of adjustment and for ensuring the safe production of the fully mechanized caving and mining face.
