摘　　要：针对华亭大柳煤矿“三软”煤层大采高工作面回撤期间自然发火隐患进行分析,合理的制定了综合的防灭火技术。对工作面防灭火技术取得的实效进行总结,确保1404工作面回撤期间的安全性。并对制定的综合防灭火技术从安全效益、经济效益、社会效益进行论证。结果表明华亭大柳煤矿“三软”煤层大采高工作面回撤期间综合防灭火技术取得了显著的经济效益,对“三软”煤层大采高工作面煤自燃防治工作具有重要的指导意义。We analyze the natural fire hazards during the retraction of the large mining face of the "three soft" coal seam in Huating Daliu coal mine and develop a comprehensive fire prevention technology. The effectiveness of the fire prevention technology is summarized to ensure the safety of the 1404 working face during retraction. The comprehensive fire prevention technology developed was demonstrated in terms of safety benefits,economic benefits and social benefits. The results show that the comprehensive anti-fire suppression techn ology during the retraction of the large mining face of the "three soft" coal seam in Huating Daliu coal mine has achieved significant economic benefits, and has important guiding significance for the prevention and control of coal spontaneous combustion in the large mining face of the "three soft" coal seam.
