神东矿区内因火灾防治探讨

    Discussion on Spontaneous Fire Prevention and Control in Shendong Coal Mining Area

    • 摘要: 神东矿区煤层埋藏较浅,层间距较近,煤层近似水平,采动后易形成大面积多层复合采空区,导致各层均具有自然发火可能性,火灾具有隐蔽性。神东矿区有近距离易自燃(自燃)煤层群开采工作面、综采放顶煤开采易自燃(自燃)煤层工作面、大采高开采易自燃(自燃)煤层工作面和高瓦斯矿井开采易自燃(自燃)煤层工作面等不同内因火灾类型。针对不同类型内因火灾给出常规防治技术路线,以期可杜绝神东矿区内因火灾事故,保证矿井安全生产。

       

      Abstract: The coal seam in Shendong Mining Area is shallow depth and approximate horizontal, close interlayer spacing. The large area multilayer compound goaf will be generated after mining. Each seam has the probability of spontaneous combustion. The types of spontaneous fire are different, including close distance easy spontaneous combustion (spontaneous combustion) coal seam working face, fully mechanized roof caving spontaneous combustion (spontaneous combustion) coal seam working face, large mining height spontaneous combustion (spontaneous combustion) coal seam working face and high gas spontaneous combustion (spontaneous combustion) coal seam working face. The routine prevention and control technology roadmap was given for different spontaneous fire types to completely eradicate spontaneous fire accidents and guarantee mine safety production.
