摘　　要：结合煤矿泡沫灭火的现场条件,研制了新型螺旋射流式泡沫发生装置,通过分析矿井大空间巷道煤自燃火区形成过程及特点,提出了泡沫灭火钻孔实施方案及高倍泡沫灌注工艺,确定了泡沫发生系统运行最佳工况。大空间巷道火区高倍泡沫灭火实践表明,高倍阻化泡沫灌注后,火区温度降至14.0℃左右,CO浓度降至0.001%以下,大流量高倍泡沫的成功实施确保了启封过程的安全,一定程度上丰富和发展了我国煤矿火灾防治理论与技术体系。Based on mine field condition of foam fire-fighting,a new spiral jet foam generator was designed.Through analyzing the forming process and characteristics of coal spontaneous combustion area at mine large space roadway,the foam fire-fighting drilling scheme and high power foam infusion technology were proposed,and the optimal operation condition of foam forming system was determined.The field practice showed that after the high power inhibition foam infusion,the fire area temperature was reduced to 14.0 ℃ and the CO concentration was reduced to less than 0.001%.The successful implementation of large-flow and high-power foam ensured the safety of unsealing process,and enriched and improve the existed mine fire disaster control theory and technical system in our country at a certain extent.
