双柳煤矿自燃火灾综合防治技术研究

Study on preventing and extinguishing technology against spontaneous combustion of Shuangliu Mine

通过对煤炭自燃发火机理的研究,结合双柳煤矿工程地质条件,对双柳煤矿煤层自燃发火特点进行了总结。分析采空区自燃"三带",并采用现场监测与数值模拟的方法对该矿33(4)11工作面采空区进行自燃"三带"划分,给出了双柳煤矿火灾综合防治技术措施,有效的控制了工作面自燃火灾的发生,保障了矿井的安全生产。

Spontaneous combustion of coal seam is one of the main disasters in mine.Based on the research on spontaneous combustion mechanism of mine and the engineering geological conditions of Shuangliu Mine,the characteristics of spontaneous combustion of coal seam in Shuangliu Coal Mine were summarized.The three zones of spontaneous combustion in gob area were analyzed and the three zones of spontaneous combustion in 33(4)11 face of Shuangliu Mine were divided by means of local monitoring and numerical simulation.The integrated control measures for fire in Shuangliu Mine were given,and the effective control spontaneous combustion of the face of the occurrence of the mine improved the safety of production.
