摘　　要：采空区遗煤自燃危害严重影响矿井安全生产,为避免遗煤自燃的发生,分析了采空区自燃“三带”分布特征,研究了工作面供风情况对采空区氧化带宽度的影响。结果表明,氧化带和散热带宽度均随工作面供风量增加而变大,当供风量小于2200 m^(3)/min时,二者近似线性增长,氧化带宽度增幅高于散热带宽度增幅。The spontaneous combustion hazard of residual coal in goaf seriously affects mine safety production.In order to avoid the occurrence of spontaneous combustion of residual coal,the distribution characteristics of "three zones" of spontaneous combustion in goaf are analyzed,and the influence of air supply in working face on the width of oxidation zone in goaf is studied.The results show that both the oxidation zone and the heat dissipation bandwidth increase with the increase of the air supply volume of the working face.When the air supply volume is less than 2200 m^(3)/min,the two increase approximately linearly,and the increase of the oxidation zone width is higher than that of the heat dissipation zone width.
