详细分析了上覆煤层采空区存在着火位置较高,发火点隐蔽等自然发火隐患以及上覆煤层采空区自然发火的特点,总结性提出了上覆煤层自然发火的预防策略,重点提出了上覆煤层立体式综合灭火技术,成功地解决了某矿上覆煤层采空区自然发火隐患,确保了矿井的安全生产。同时,也为近距离煤层采空区的防灭火提供了宝贵的经验。
This paper analyzes in detail the characteristics of spontaneous fire hazards such as high fire position, concealed ignition point and spontaneous combustion in overlying coal seam, and puts forward the preventive strategy of spontaneous combustion of overlying coal seam, Overlying coal seam three-dimensional integrated fire extinguishing technology, successfully solved a mine overlying seam spontaneous combustion potential hazards, to ensure the mine’s safe production. At the same time, it also provides valuable experience for fire prevention and extinguishment of the mined-out area near coal seam.
