Effect of Pre-Oxidation Temperature on Coal Body in Normal Temperature Oxidation
In the process of preoxidation,the temperature distribution will change,which will affect the spontaneous combustion characteristics of coal.Through the normal temperature oxidation test,the changes of coal core temperature,CO,CO2 and other index gases of coal at different preoxidation temperatures were analyzed.The conclusion was that spontaneous combustion of coal will be promoted with the increase of preoxidation temperature,and the possible environmental reasons were analyzed and discussed.
