摘要
以呼和乌素煤矿4104主运顺槽和辅运顺槽及其联络巷道为实验原型,根据流体相似理论以1∶20的比例构建了相似实验模型,并在其中的一段巷道中进行了巷道火灾中火区阻力的实验测定.测定结果表明,在巷道风量不变的条件下,巷道火灾时期火区阻力的大小与火源热释放特性有关,即火灾的火区规模、燃烧温度和释放的热量越大,火区阻力也越大.
According to the theory of fluid similarity, the experimental model was established using Huhewusu 4104 main transport trough, auxiliary transport trough and contact roadway as antitypes in proportion of 1：20, and the experimental determination of fire zone resistance in one of the roadways was carried out. The results showed that the value of fire zone resistance was related to the characteristics of fire heat release while the wind was constant. It indicates that the larger are the fire scale, fire temperature and heat-releasing, the larger is the resistance of the fire zone.
