The test method and principle that isothermal difference leading the elevated temperature experiment and the large coal spontaneous ignition experiment are different, data acquisition methods are also different, the content and calculation basis of coal spontaneous combustion characterization parameters and solution are slightly different. In order to realize the comparative analysis of isothermal difference leading experiment and large coal spontaneous combustion experiment, it selects samples of Zhaoxian Coal Mine to conduct large coal spontaneous combustion experiment (defined as ZXDY) and isothermal difference leading experiment (defined as ZXYM), and to make an analysis of the characterization parameters of coal spontaneous combustion, obtaining the characteristics and applicability of the two experimental methods of coal spontaneous combustion characterization parameters.
