| 摘 要： | 通过巷道内木材火试验,从氧气浓度、温度、实验现象等方面分析,判定了本次木材火实验产生了次生灾害,同时验证了A·罗伯特燃烧类型评判标准、风流与巷壁热交换基本定律等相关理论的正确性。最后为了防止次生灾害发生,提出了相关建议。

| Abstract: | In this paper,the experiment has shown secondary disasters took place in tunnel timber - fire through the analysis of oxygen concentration,temperature,experimental phenomena,empirical data,which get from this experiment. And it also verify that the A o Robert evaluation criteria of burning type,heat exchange basic law and other related theories are correct. Finally in order to prevent secondary disasters,this paper presents some relevant recommendations. |
