实践证明,通风管理不善造成采空区大量漏风,是引起采空区煤炭自燃的主要原因之一。所以建立合理的通风系统,加强日常通风管理,对防止采空区自然发火有着重要意义;另一方面,当井下一旦发生火灾时,只有采取正确的通风措施,及时调整风流流动状况,才能迅速有效地扑灭火灾,缩小事故范围和减少灾变造成的损失。因此,“以 Practice has proved that poor ventilation management causes a large amount of air leakage in the goaf, which is one of the main causes of coal spontaneous combustion in the goaf. Therefore, to establish a reasonable ventilation system and to enhance daily ventilation management is of great importance to prevent spontaneous combustion in the goaf. On the other hand, when a well fire occurs in the underground, correct ventilation measures and timely adjustment of the ventilation and flow conditions can be effective immediately Extinguish the fire, narrow the scope of the accident and reduce the losses caused by catastrophes. Therefore, "to
