针对煤层自然发火工作,注氮均压灭火技术迅速有效地解决了火势发展迅速造成的下风侧风流中CO含量迅速升高而导致巷道、工作面封闭的情况发生,避免了矿井因采、掘工作面封闭造成的巨大经济损失,并有效的抑制了漏风地点的漏风量,为常规灭火手段创造足够的时间。
Aiming at the spontaneous combustion of coal seam, the technology of pressure equalization and fire extinguishing with nitrogen injection can quickly and effectively solve the situation that the content of CO in the leeward side wind flow caused by the rapid fire development rapidly increases, resulting in the closure of roadway and working face, avoiding the mining Surface closure caused huge economic losses, and effectively curb the leakage of air leakage sites, to create enough time for conventional fire fighting means.
