Based on experiment results and theoretical analysis,pointed out that the method of coal susceptibility to spontaneous combustion determination with fluid oxygen adsorption can not present the essence of coal oxidation process and oxidation reaction. The method is incorrect,paying attention at one aspect and ignoring the rest.The method is not reasonable for coal susceptibility to spontaneous combustion determination.Sus- ceptibility to spontaneous combustion of coal reflects chemical property of coal oxidation with oxygen absorption and heat release at low temperature.Coal's susceptibility to spon- taneous combustion is mainly decided by the number of molecules with reaction activation energy and activation molecule production rate at certain temperature.Therefore,index of susceptibility to spontaneous combustion should adopt accumulative value or trend of heat release or oxygen adsorption during oxidation process. 展开更多

通过理论与实验结果的分析,指出流态色谱吸氧法测定煤炭自燃倾向性高低未能反映煤的氧化过程与氧化反应的实质,流态色谱吸氧法的指标体系不科学性;同时指出煤的自燃倾向性是反映煤在低温氧化条件下煤的吸氧与氧化放热的化学性质,煤的自... 通过理论与实验结果的分析,指出流态色谱吸氧法测定煤炭自燃倾向性高低未能反映煤的氧化过程与氧化反应的实质,流态色谱吸氧法的指标体系不科学性;同时指出煤的自燃倾向性是反映煤在低温氧化条件下煤的吸氧与氧化放热的化学性质,煤的自燃倾向性主要由煤在某反应温度条件下具有反应活化能值的分子数及反应分子活化速率决定的;煤炭自燃倾向性高低的指标应采用氧化过程的放热量(或吸氧量)的积累指标或趋势指标。 展开更多
