Influence mechanism of pre-oxidation on the secondary oxidation characteristics of coal: insights from TG-DSC-FTIR analysis
release peaks, with cumulative total release increasing by 7.27-10.13% relative to raw coal. This study elucidates the mechanism by which pre-oxidation intensifies the secondary oxidation process of coal through reducing activation energy and altering reaction process, providing essential theoretical foundation and experimental data for accurately assessing the spontaneous combustion risk and environmental impact of pre-oxidized coal.
