摘要
综合机械化采煤工作面撤架期间的自然发火及瓦斯防治技术是易自燃煤层、瓦斯矿井经常面临的一大课题,通过选择封闭注氮回撤支架的方法,并采取综合性防灭火及瓦斯防治技术,可有效防治煤炭自然发火、防止瓦斯超限,保证安全生产。
Spontaneous combustion and gas control technology at fully mechanized working surface during withdrawing support period is a major issue in easy spontaneous combustion seam and gas mine. Through selecting the method of closed nitrogen injection to withdraw-al support and taking comprehensive fire prevention and gas control technology, coal spontaneous combustion can be effectively preven- ted and controlled, which prevents gas overrun and ensures safety production.
