摘要
对潞安集团一缘矿15#煤分别通入30%和60%2种不同浓度CO2气体,吸附24 h后,结合程序升温氧化和热重差热分析实验,研究煤样吸附CO2后耗氧速度、CO产生率、特征温度等自燃特性参数的变化规律。
Two different concentrations of CO2 concentrations were 30% and 60%,were passed into Yiyuan mining area 15# coal seam of Lu＇an Group,after adsorption for 24 h,combined with temperature-programmed oxidation experiment and thermal gravimetric and differential thermal analysis experiments,some variation rule of spontaneous combustion parameters such as oxygen consumption rate,CO production rate,characteristic temperature were studied.
