神东矿区内因火灾防治探讨

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

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。

The coal seam in Shendong Mining Area is shallow depth and approximate horizontal, close interlayer spacing. The large ar- ea muhilayer 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 combus- tion） 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 ~uarantee mine safety nroduction.
