| 摘 要： | 通过程序升温实验研究了煤炭的自燃特性，测定了不同粒度煤样在不同温度下产生CO，CO2等气体的浓度，讨论了指标气体的选择，分析了CO，CO2等气体浓度随温度的变化规律，得到了耗氧速度与煤温及煤温及煤体粒度的关系，结果表明，煤体粒度越小，温度越高，则煤氧复合的强度越大，本实验的研究结果对煤矿火灾的防治具有指导作用。

| Abstract: | The characteristics of coal spontaneous combustion were investigated through programmed temperature experiment and the concentration of CO, CO2 etc for coal with various sizes was measured at different temperatures. The selection of index gases was discussed. The law of concentration change for CO, CO2 etc and the relation of consuming oxygen velocity to coal temperature and size were analyzed. The smaller the coal size and the higher the temperature, the more intense the reaction of coal and oxygen. The results can direct the prevention and treatment of fire in mine. |
