Abstract
In order to investigate the influence of magma intrusion on the low-temperature oxidation characteristics of coal,we take the metamorphic coal and the original coal in the magma intrusion area of Xin'an Mine as the objects,and the difference of the low-temperature oxidizing thermal effect between the metamorphic coal and the original coal is comparative-ly investigated through the experiments carried out by the industrial analysis and the C80 microcalorimeter.The results showed that:the moisture and volatile matter of metamorphic coal decreased,and the fixed carbon,ash and metamorphic de-gree increased;under different heating rates,the initial exothermic temperature point and thermal equilibrium temperature point of metamorphic coal were lower than that of the original coal,the exothermic amount of metamorphic coal was higher than that of the original coal,and the activation energy was lower than that of the original coal,and the spontaneous combus-tion hazard of the metamorphic coal was higher than that of the original coal caused by the effect of magma intrusion;and the smaller the heating rate,the lower the characteristic temperature point of the metamorphic coal and the original coal,and the greater the exothermic amount,the smaller the energy required for coal oxygen reaction.关键词
