中梁山南矿K₁煤自燃特性实验研究

摘要: 采集中梁山南矿煤样，进行煤自然发火实验及相关实验。对煤氧化升温过程进行了研究和分析，得到煤样静态吸氧量，确定了以CO气体为主、辅助以C₂H₄气体的煤自燃监测气体指标。建立数学模型，解算得到了煤样最短自然发火期为51 d。

Abstract: Coal sample was collected from Zhongliangshan South Coal Mine for experiment and relative experiments on coal spontaneous combustion. Coal oxidation warming process was studied and analyzed, from which quantity of static oxygen absorption was measured, and CO was mainly adopted as gas index for monitoring coal self-ignition, assisted with C₂H₄. Mathematical model was built, from which minimal time of coal self-ignition was fifty-one days.
