摘　　要：对51519综采放顶煤工作面采空区煤层自燃事件,采用矿用混凝土泵输送、喷射粉煤灰复合胶体进行灭火治理,并对采空区停采线附近巷道充填粉煤灰封堵采空区漏风,从而使采空区内的CO浓度迅速下降并最终消失,为安全生产提供保障。For the spontaneous combustion happened in 51519 fully-mechanized top-coal mining face, the transforming and ejecting of fly ash composite colloids with concrete pump were used to fight fire. The air leakage in gob area was sealed by filling fly ash in roadways near the end-mining lines so that the CO concentration decreased and disappeared at last, which guaranteed the safety production.
