摘要
氮气防灭火技术是防治煤层内因火灾的有效技术措施之一,但氮气轻,易流失,本文针对新峪矿5110综放工作面的实际情况,采用了氮气泡沫结合的方法进行防灭火,对注氮设备、注氮方式、注氮工艺、进行了详细的阐述,并对防灭火效果进行了深入分析。
Fire fighting technology of nitrogen injection is one of the most effective technical measures in preventing coal seam fire.However,nitrogen is light and loses easily.Regarding the practical situation on 5110 fully mechanized coal face of Xin Yu mine coal,this thesis analyzes the combination of nitrogen and foam for firefighting technology.It elaborates the nitrogen produce equipment,nitrogen injection way,and nitrogen injection technology.Furthermore,it analyzes the fire control results in details.
