摘要
采用程序升温实验,研究了东庞煤样的自燃特性,测定了煤样在不同热解温度下一氧化碳、二氧化碳、甲烷、乙烯、乙炔等气体的浓度,确定了这些气体的检出温度。对比指标气体优选原则,分析了自然发火指标气体随温度变化的规律性,选出了适合东庞矿煤层自然发火预测预报的指标气体。
The spontaneous combustion characteristics of coal samples fromDongpang Coalmine were determined by programmed heating experiment. The concentrations and initial e- mission temperatures of CO, CO2, CH4, C2 H4, C2 H2 were measured. According to the optimi- zation principle of the index gas, the laws of index gases varied with the temperature were ana- lyzed and the index gases suitable for the prediction and forecast of coal spontaneous combustion of Dongpang Coalmine were determined.
