| 摘 要： | 对洛市矿区61个委托煤样的色谱吸氧法自燃倾向性鉴定表明,同一煤种煤的吸氧量随挥发分、煤的真相对密度、灰分增大而减小的趋势较明显,吸氧量随全硫含量增大而增大的趋势较明显,但对具体的一个矿井或煤层而言,应参考煤自燃倾向性鉴定等级,结合矿井地质条件、采掘布置、通风系统以及所采取的防灭火措施的影响等因素分析其自然发火的危险程度.

| Abstract: | According to the appraisal of spontaneous ignition tendency in 61 coal samples by chromatographic oxygen - uptake method, the authors have found out that the amount of oxygen - uptake in the same coal type has reduced along with the increase of volatile matter , true relative density and ash content and increased along with the increase of sulfur content. Therefore, they have come to a conclusion that as far as a certain colliery or seam is concerned, the hazard degree of spontaneous ignition should be analyzed according to the following factors - the rate of spontaneous ignition tendency, geologic condition, mining layout, ventilation system and the effects of fire prevention measures. |

| Keywords: | spontaneous ignition tendency oxygen- uptake amount volatile matter sulfur content ash content |
