综采工作面采空区遗煤自燃防治技术研究

Research on Prevention and Control Technology of Coal Spontaneous Combustion in Goaf of Fully Mechanized Mining Face

井下常因遗煤自燃引发严重火灾,造成人员伤亡、影响煤矿效益。遗煤自燃火灾通常是因工作面进度慢、处置不当、遗煤及煤尘发生氧化而引起,因其位置的特殊性,火灾消除难度系数高,矿井需实施有效的防灭火措施,避免灾难发生。

Serious fires often occur underground due to spontaneous combustion of residual coal,resulting in casualties and affecting the efficiency of coal mines.The spontaneous combustion of residual coal is usually caused by slow progress,improper disposal,and oxidation of residual coal and coal dust in the working face.Due to the unique location,the difficulty coefficient of fire elimination is high.Effective fire prevention and extinguishing measures need to be implemented in mines to avoid disasters.
