In this paper, analysis was made on the inflection point temperature of the chromatographic oxygen absorption capacity of different water-bearing coal samples in Mengba Mine, the “0”-value point and inflection point temperature and the critical temperature of DSC (differential thermal analysis) system as well as the ratio inflection point temperature of ψ(CO2)/ψ(CO) by using GC-4075 coal spontaneous combustion tester,DSC( differential thermal analysis) system and the experimental system of programmed temperature rise,and the influence law of the moisture on the characteristic temperature of coal was determined,which thus provided the basic data and theoretical support for the prediction of spontaneous combustion in the main mining seams in Mengba Mine.
