| 摘 要： | 在总结7种典型火灾气体指标的基础上,采用修正后的氧消耗浓度计算方法,分析了某矿因自然发火封闭的火区内火灾气体指标的特点和随封闭时间变化的曲线。研究发现:综合应用几种典型火灾气体指标能够较为准确的判断隐蔽火点或封闭火区的燃烧状况;火势较小时,特里克特比率对燃烧物种类的判断能力较弱;在对火区温度进行分析时,个别高温点容易被忽视;不同监测点指标值的大小次序能够为隐蔽火源点和燃烧重点区域位置的确定提供指导。

| Abstract: | Base on the gas index of the 7 typical fire disasters,the calculation method of the corrected oxygen consumption density was applied to analyze the features of the fire disaster gas index in the spontaneous combustion sealed fire area and the curves with the sealed time variation in a mine.the study showed that the comprehensive application of several typical fire disaster gas indexes could be correctly to judge the combustion status in the hidden firing location or sealed firing area.As for a small firing ... |
