Characteristics of coal spontaneous combustion and kinetics in Juye mining area
摘要
Abstract
Considering the situation that the spontaneous combustion of coal seamNo.3 in Juye mining area is se-rious, coal samples from upper seam 3 and lower seams 3 were selected as research object. In this paper, coal physical parameters test, thermogravimetric analysis and Fourier infrared spectrum were used to conduct experi-mental study on the characteristics of spontaneous combustion and kinetic parameters of seam 3 in Juye mining area. Experimental results show that coal of Juye mining area belongs to the classⅡof spontaneous combustion coal, and the coal pores are mainly macropore and mesopore; Activation energy of coal is 94~123 kJ/mol in the stage of weight loss induced by dehydration, 230~240 kJ/mol in the stage of weight gain induced by oxyge uptake. Coal molecule contains a large number of active functional groups, including hydroxyl, methyl and methylene, which are the key chemical structure leading to spontaneous combustion of coal in Juye mining area.关键词
