摘要：

It has great importance to study on the characteristic temperatures for prediction and prevention of coal spontaneous combustion. Base on the temperature programmed experiment system and original index gases analysis, establish growth rate analysis to test index gases of CO and C2H4, CO/CO2 and alkane ratio so that to determine the characteristic temperatures of different metamorphism degree of coal, and compare it with index gases analysis. The results show that the extreme values of growth rate analysis are characteristic temperature points for coal spontaneous combustion, and different metamorphic coal has different extreme value. What's more the growth rate analysis is more concise, effective to determine the points and reduce the uncertainty. (c) 2014 Published by Elsevier Ltd.
