煤矸石放热危险性与微观基团相关性研究OACSTPCD
Study on correlation between exothermic risk of coal gangue and microscopic groups
为了探究煤矸石自燃过程放热危险性及其与微观基团的相关性,利用红外光谱实验和差示扫描量热实验测试了 4 种煤矸石的微观结构和自燃放热特征;基于放热量和活化能建立了煤矸石自燃危险系数,并确定了其与微观基团之间的相关性.结果表明:4 种煤矸石(编号CG1、CG2、CG3、CG4)均含有取代苯,‒C=C‒、Ar‒CH、‒CH3、‒CH2‒、Al‒CH、‒OH、‒C‒O‒、‒C=O及无机物等基团,但各基团的含量存在显著差异;煤矸石的自燃放热可分为水分蒸发,…查看全部>>
In order to explore the exothermic hazard of coal gangue in the process of spontaneous combustion and its correlation with microscopic groups,the microstructure and exothermic characteristics of four kinds of coal gangue(CG1、CG2、CG3、CG4)were tested by infrared spectrum experiment and differential scanning calorimetry experiment;based on the exothermic heat and activa-tion energy,the spontaneous combustion risk coefficient of coal gangue is established,and th…查看全部>>
