摘 要:大兴煤矿N2-405工作面受火成岩侵入影响煤体变质焦化严重,易自燃发火,通过立项对CO来源及自燃发火参数进行研究,回采期间制定并实施了均压通风、采空区氧化带压注氮气、三项泡沫、充填河砂、浮煤喷洒阻化剂以及回撤过程中采用支撑掩护式全负压通风方法等一系列综合防火措施,取得了最佳防火效果,防止了自燃发火事故发生,保证了工作面安全回采结束。Daxing Coal Mine N2- 405 face is influenced by igneos roke, so coal body becomes bad and coked serious, natural catch fire easily. Through studying on CO source and natural catch fire paremeters, equal pressure ventialation is drawn up and put into effect during working. A series of comprehensive fire prevention measures about shield support full negntive pressure vent lating way is used by gob area oxidizing band pressure poured nitrogen, three item foam, full of river sand, float coal spray, stopping agent and returning to remove. It gets a best fire prevendon, effect, prevents natural catch finre accidents, ensures safe stoping to be finished of working face.
