注氮防灭火技术在后安煤矿的实践与应用
Practice and Application of Nitrogen Injection Fire Extinguishing Technology in Hou’an Coal Mine
摘要:
针对后安煤矿090204工作面采空区自燃的事实，并且根据实际情况采取了井下注氮防灭火技术进行防灭火。阐述了注氮防灭火的工作原理，并对使用注氮防灭火技术的特点和工艺进行了认真地分析，分析认为注氮防灭火收到了良好的效果，保证了矿井的安全生产。
Abstract:
Aiming at the fact of spontaneous combustion in the goaf of 090204 working face of Hou’an Coal Mine, and adopting underground nitrogen injection fire extinguishing technology to prevent and extinguish the fire according to actual conditions, the working principle of nitrogen injection fire prevention and extinguishment was expounded, and the characteristics and process of using ni-trogen injection fire prevention and extinguishment technology were carefully analyzed. The analysis believed that nitrogen injection fire prevention and extinguishment received good results and ensured the safe production of the mine.
