煤自燃火灾防治技术研究

The research of fire-fighting and extinguishing technology on coal self-ignition

分析煤炭的火灾危险性及煤自燃的特点 ,讨论煤自燃火灾扑救的方法 ,提出适合于煤炭自燃火灾扑救的新型灭火剂。小型灭火试验及在实际煤自燃火灾扑救中的应用结果表明 ,新型灭火方法可以有效降温并减小煤体的空隙率 ,减缓煤的煤氧复合作用 ,具有良好的灭火和抗复燃效果。

In this paper, the fire hazard of coal and characteristic of coal self-ignition are analyzed. The extinguishing methods of coal self-ignition are discussed. The new extinguisher for extinguishing coal self-ignition is put forward. The experiment results from small scale extinguishing experiment and applicable experiment of extinguishing coal self-ignition in coal using this new technology show that this new extinguishing methods can not only effectively lower temperature of coal , reduces hole rate but also lighten the chemistry reaction of coal and oxygen. Thus it obviously has better fire fighting and extinguishing and resisting combustion effects.
