5244综放工作面在回采过程中,采空区浮煤氧化高温导致CO浓度超限情况,有遗煤自燃现象,为保证回采工作的顺利进行,对该工作面进行防灭火技术研究,通过灌浆、注氮、注凝胶等技术措施,并应用新型防灭火材料-史达夫防灭火剂,取得了良好的效果:通过气体采样分析发现,CO气体浓度保持在12×10~(-6),有效防止了遗煤自燃,保障了回采工作顺利安全进行。 5244 fully mechanized caving face in the process of mining, goaf floating coal oxidation temperature lead to CO concentration over the situation, with coal spontaneous combustion phenomenon, in order to ensure the smooth recovery of the work carried out on the face anti-fire fighting technology research, through the grouting , Nitrogen injection, gel injection and other technical measures, and the application of a new anti-fire extinguishing material - Stardf anti-fire extinguishing agent, and achieved good results: gas sampling analysis found that CO gas concentration remained at 12 × 10 -6, , Effectively prevent the spontaneous combustion of coal left to ensure the smooth and safe mining work.
