摘　　要：运用热重分析手段对几种阻化剂进行了实验研究,运用化学反应动力学方程计算得到了原煤样与阻化煤样的活化能。实验和计算结果表明,同种阻化剂对不同的煤样具有选择性,不同的阻化剂对相同煤样的阻化效果不同。为此提出基于煤的着火活化能确定煤自燃阻化效果的定量计算方法,对选择煤自燃阻化剂具有重要的理论与实际意义。Thermogravimetric analysis technique was used to study several inhibitors and the activation energy of original coal samples and coal -like ones was gained by the chemical reaction dynamic equation. The experimental and calculated results showed that the same kind of inhibitor had selectivity for different coal samples and different kinds of inhibitors had different inhibiting effect on the same coal sample. For this reason, a quantitative calculation method determining coal spontaneous ignition inhibiting effect by ignition activation energy of coal was proposed. It had theoretical and practical significance to select inhibitors of spontaneous ignition of coal.
