中文摘要：

本文首先指出了我国现行的煤自燃倾向性色谱吸氧鉴定法的不足之处，同时给出了煤自燃倾向性鉴定标准的基本原则。根据绝热氧化理论和绝热氧化方程，设计了相应绝热氧化实验装置。通过理论和实验研究，提出了能够反映煤自燃关键阶段，即低温氧化阶段动力学参数活化能E作为煤自燃倾向性鉴定指标，并测试了五个典型煤样的低温氧化活化能E，同时根据该指标对煤自燃倾向性等级进行了初步划分。最后，通过现场煤自燃发火期与煤物理吸附氧量和低温氧化活化能E的对比，对该指标的实用性和科学性进行了检验。

英文摘要：

This paper firstly indicates the shortages of the method for identifying tendency of spontaneous combustion of coal by oxygen adsorption with chromatograph in China. Simultaneously , some principles about identifying the tendency of spontaneous combustion of coal are brought forward. Based on the adiabatic oxidation theory and equation of spontaneous combustion of coal, the adiabatic oxidation equipment is designed and manufactured. Through the theory of adiabatic oxidation and the simulation experiments of spontaneous combustion of coal, activation energy E during 40～70℃, which is the kinetic parameter of low-temperature oxidation of coal, is chosen as a new index of tendency of coal to self-ignite, and the activation energy of five coal samples is obtained by testing and calculating. According to the activation energy, the new grades of coal to self-ignite are put forward. At last, the practicability and correctness of the new identification method is proved through comparing spontaneous combustion period with Physisorption of oxygen and low-temperature oxidation activation energy of coal.
