淮南丁集矿1272(3)工作面综合防灭火技术研究

Research on Comprehensive Fire Prevention Technology at 1272(3) Working Face in Huainan Dingji Coal Mine

针对淮南丁集矿1272(3)工作面回采过程中,采空区的遗煤在连续供氧、聚热等条件下会造成煤炭自燃,提出了采取采空区防漏风、灌浆、注氮、束管监测等综合防灭火技术措施,确保工作面的安全生产,为其他同类工作面煤炭自燃的防治提供了宝贵经验。

According to the Huainan Dingji coal mine 1272（3） in the process of mining, the residual coal in the goaf is in the condition of continuous oxygen supply and heat accumulation, will cause coal spontaneous combustion. Adopted the goaf air leakage prevention, grouting, nitrogen injection, beam tube monitoring comprehensive fire prevention technical measures, to ensure the safety of the working face, and provide valuable experience for the prevention and control of coal spontaneous combustion in other similar working face.
