摘要
为了有效控制和扑灭井下采空区火灾,以注氮为主的防灭火是井下预防火灾和减少火灾事故损失的一种非常有价值和实用的技术。鑫顺煤矿针对综放工作面自然条件,通过合理选择注氮方法和工艺,制定操作规范和注氮技术要求,现场实施后有效抑制了工作面采空区煤炭自燃发火现象,对于开采自燃煤层煤矿火灾防治具有积极的推广价值。
In order to control and extinguish fire in goaf underground effectively,using nitrogen injection to prevent and extinguish fire was is a very valuable and practical technology,it could prevent fire and reduce fire accident loss.For natural conditions of mechanized working face,through the reasonable selection of method and nitrogen injection technology,developed standardized operation and nitrogen injection technology requirements,suppressed spontaneous combustion phenomenon in working face goaf after the implementation effectively,it had positive popularization value for preventing fire in spontaneous combustion coal.
