In order to prevent and control the spontaneous combustion of residual coal in alkaline coal mines, the effect of coal particle size on coal oxidation self-ignition in an alkaline environment had been explored. Through water quality tests and Fourier-transform infrared spectroscopy (FTIR) tests, the microstructural changes of coal with different particle sizes soaked in alkaline solution were analyzed and judged. The oxidation kinetics of coals with varying particle sizes soaked in alkaline solutions had been investigated through programmed heating experiments and calculations of apparent activation energy. The results show that during the process of soaking coal particles of varying sizes in an alkaline solution, the redox potential (ORP) and total dissolved solids (TDS) exhibit significant changes as soaking time increases, the content of active functional groups in the coal increases, the coal samples with a particle size of 0-1 mm exhibit significantly higher levels of active functional groups compared to the other test groups. After soaking in an alkaline solution, coal samples with smaller particle sizes exhibit lower apparent activation energy. As particle size decreases, the amount of oxygen consumed during oxidation increases, enhancing the oxidation capacity. Consequently, the quantities of CH₄, and C₂H₆ gases released in the later stages of oxidation also progressively rise. In an alkaline environment, smaller coal particle sizes experience more severe erosion. The lower the energy barrier that must be overcome for oxidation, the more intense the coal-oxygen composite reaction becomes.

为预防和治理碱性环境煤矿的遗煤自燃现象，探究碱性环境中煤粒径大小对煤氧化自燃的影响。通过水质检测试验和傅里叶红外光谱（FTIR）测试，分析判断碱性溶液浸泡不同粒径煤的微观特征变化；通过程序升温试验和表观活化能计算得出碱性溶液浸泡不同粒径煤的自燃特性。结果表明：碱性溶液浸泡不同粒径煤的过程中氧化还原电位（ORP）和总溶解固体（TDS）随浸泡时间的增加变化幅度较大，煤体的活性官能团含量增加，粒径为0~1 mm的煤样活性官能团较其他试验组的显著偏高；碱性溶液浸泡后粒径越小的煤样，表观活化能越低，氧化时所消耗的氧气含量越多，氧化能力随粒径的减小逐级增强，氧化后期CH₄、C₂H₆气体析出量也逐步上升。碱性环境中煤的粒径越小受到的侵蚀越严重，氧化所需突破的能量壁垒越低，进行煤氧复合反应的程度越剧烈。
