对于矿井通风系统的稳定性而言，正常生产时期的影响因素对系统的影响可以限制在一定的范围之内，可以通过加强通风管理来实现。但矿井通风系统是一个开放的系统，对外界有密切的联系，各种外界的条件都一起特有的方式作用于矿井通风系统。在这些外部因素中，有些因素对矿井通风系统的影响非常巨大，有时是灾难性的。然而，这样的灾难性事件通常难以预测、预报，通常具有突发性。这种情况下矿井通风系统稳定性与正常生产时期的矿井通风系统稳定性有本质的区别，应采用不同的方法进行分析和研究。通风系统的好坏与火灾防治、瓦斯事故、粉尘治理、热害治理等都是密切相关的，由于井下主要的危害体现在影响巷道的可通性上
For the stability of the mine ventilation system, the normal production period of the impact of factors on the system can limit the scope of a certain can be accomplished by strengthening the management to achieve ventilation. But the mine ventilation system is an open system is closely linked to the outside world, a variety of external conditions with a unique way of acting on the mine ventilation system. In these external factors, some factors on the impact of the mine ventilation system is very strong and sometimes disastrous. However, such catastrophic events are usually difficult to predict, forecast, usually with a sudden. This case the stability of the mine ventilation system and the normal production period of the stability of the mine ventilation system is essentially the difference between different methods should be used for analysis and research. The quality of ventilation systems and fire prevention, gas accidents, dust control, heat treatment and other harm are closely related, as the underground against the major roadway in the impact of transparency on
