复杂条件下超长综放工作面防灭火技术

Fire Prevention and Extinguishing Technology at Super-long Fully Mechanized Caving Face Under Complex Conditions

通过在不同时期采取有针对性的通风方式、堵漏风、注氮和预防性注浆等综合防灭火技术,有效地防止了011604超长综放工作面的自然发火,并阻止了上部9#煤层小窑高温区内有害气体的侵入,确保了矿井安全顺利生产。

Through adopting targeted comprehensive fire prevention and extinguishing technology such as ventilation mode, plugging air leakage, nitrogen injection and preventive grouting and other technologies at different stages, the spontaneous combustion at 011604 su- per - long tully mechanized caving face is effectively prevented, which prevents harmful gas invasion fi＇om upper 9# coal seam small pit high temperature zone and ensures the smooth production of mine safety.
