Abstract: Aiming at the problem of spontaneous combustion of coal gangue in Yangmei Group, the mineral properties of coal gangue were analyzed firstly. The carbon in coal gangue was studied from the view of particle size by screening test. The sulfur in coal gangue was quantified by determination of total sulfur. The su8020 scanning electron microscope was used to study the sulfur embedding state and the distribution of sulfur under different liberation degrees. The image processing analysis was carried out by ImageJ software to provide a new method for quantifying the sulfur distribution law.
