摘　　要：首先介绍了用锥形量热计测定矿用可燃物燃烧特性的测试方法 ,并对几种不同类型的矿用输送机胶带及木材进行了对比实验 .实验结果表明 :非阻燃的输送机胶带释热速率最高 ,阻燃输送机胶带产生的毒气危害性最大 .针对井巷网络火灾的特点 ,还对通风巷道中的火源燃烧特性进行了研究 ,介绍了在中国矿业大学矿井火灾综合模拟实验系统中进行的网络火灾线火源的火焰蔓延速率。The method of utilizing the cone calorimeter to measure the combustion properties of mine combustibles was presented. Based on the method, some contrasting experiments among different kinds of mine conveyor belts and timber were conducted. Experimental data obtained indicate that non flame retardant belts have a higher heat release rate, and flame retardant belts have more toxicity. From the characteristics of fire in a roadway network, the properties of fire sources in a ventilated tunnel were also investigated. Experiments of linear fire source were conducted in the Mine Fire Experimental System at CUMT. The results obtained, such as the spreading rate of flame, the distribution of temperature, the effect of combustion zone on airflow's reduction, were introduced.
