摘　　要：针对阳泉五矿15#煤层自然发火期短、易自燃等特点,采用程序温升氧化实验对煤的自燃吸氧和发火特性进行分析,并选择CO作为指标气体、ICO指标作为辅助指标,研究了不同种类及浓度的阻化剂对煤层阻化抑制自燃的实验,优选出最佳阻化效果的浓度配比为:氯化钙为30%、氯化镁为15%、氢氧化钙为30%、硅酸钠为20%。该研究可为矿井防灭火提供实验基础参数。Aiming at the characteristics of Yangquan No.5 coal mine 15^#coal seam,which is inflammable and has short spontaneous combustion period,the spontaneous combustion character and oxygen uptake process of coal are studied through the heating-programmed oxidation experiment.Inhibitory effect of different inhibitor on coal seam spontaneous combustion is studied during the experiment,with CO selected as the index gas and ICO as the auxiliary index.The concentration ratio for the best inhibitory effect is determined with 30% calcium chloride,15% magnesium chloride,30%calcium hydroxide and 20% sodium silicate,the study can provide experimental basis for spontaneous combustion prevention.
