Based on the specific analysis of No. 5 coal seam geological condition and coal seam wind oxidation characteristics of Jinbei Mine, wind oxidation characteristics distribution law was studied from structural factor, thickness of overlying rock, coal seam roof feature and coal seam structure. The result showed that the No. 5 coal seam Wind Oxidation was mainly affected by geological structure, with mainly vertical wind oxidation, which distributed along the east mining field anticline axis, influenced by lithology of coal seam roof and crack growth degree, different sites of coal seam, wind oxidation degree is different, the study provides geological basis for mine production.
