煤样自燃性升温程序实验研究

摘要

Taking coal samples from the Tongchuan coalmine as test specimens, using self developed coal seam spontaneous combustible heating up experimental system, carried out coal seam spontaneous combustion process experimental simulation.On the basis of tested data, analyzed coal temperature, gas rate and indicator gases circumstances, worked out spontaneous combustion characters of critical temperature, cracking temperature etc.The results have guiding significance on coalmine analysis and coal seam spontaneous combustion process prediction.%以铜川煤矿煤样为测试样品,利用自主研发的煤层自燃性升温的实验系统,对煤层的自燃过程进行实验模拟.根据实验测试数据对煤温与供气量以及实验过程的指标气体情况进行分析,得出煤层自燃性的临界温度、干裂温度等各个自燃特性.实验结果对煤矿分析和预测煤层自燃的过程具有指导意义.
