摘要
为了给自燃煤层的防灭火控制措施制定提供依据,以新疆西山煤样为研究对象,进行了室内热重试验测试得出了的TG和热重微分(DTG)曲线,根据对TG-DTG曲线和煤样红外谱图的得到了分析通过分析得出了煤自燃过程的8个特征温度,并确定出了相应的温度范围。
Experiments on the characteristic temperatures in coal spontaneous combustion is carried out using the Xishan coal from Xiangjiang region,and obtains the relationship between TG and DTG.The eight characteristic temperatures are obtained from the TG-DTG curve and the infrared spectrum of coal sample,and its temperature range is given.The experimental results can provide technical basis for judging the spontaneous combustion in Xishan coal seam.
