在分析采区进风系统巷道火灾时风量变化原因的基础上,进行了采区进风系统相似模拟实验.结果表明:采区进风系统巷道发生火灾时,对主运顺槽和辅运顺槽之间的联络巷风量影响很大,尤以对靠近火灾点的联络巷风量影响最大,与火灾的发展、稳定燃烧和衰退过程相对应,巷道火灾对采区进风系统风量的影响也经历逐渐增大,达到最大和逐渐减小的过程.
Based on the cause of air variation in the period of tunnel fire in air supply system, the similarity simulation experiment of air supply system was carried out. The results showed that when the air supply system was on fire, the air volume in crossheading between the main crossheading and the auxiliary crossheading was mainly influenced, and the crossheading near the air supply system was under the greatest impact. The impact of tunnel fire on the air supply system was found to follow the process of gradual increase, reaching maximum and gradual decrease corresponding to the developing, stable and decline process of the tunnel fire.
