Influence law of air flow and water immersion duration on the risk of secondary oxidation spontaneous combustion of coal

Abstract To further elucidate the variations of secondary oxidation spontaneous combustion risk of lignite under different air flows and immersion time. Secondary oxidation experiments of short-term water-immersed coal and long-term water-immersed coal were conducted under four air flows. The result...
