瓦斯矿井升级突出矿井后通风系统设计优化

矿井通风系统的可靠性直接关系到矿井通风安全及矿井防灾抗灾能力。为了保证安全生产，矿井的通风系统必须随着矿井瓦斯等级的变化而提升，满足矿井瓦斯治理、防治突出的新要求。不同瓦斯等级的矿井对通风系统的要求不同，结构简单、安全可靠、经济合理、与矿井瓦斯等级相适应的通风系统，可以保障矿井安全生产、实现矿井的可持续发展。为此，总结了陈四楼煤矿瓦斯矿井升级突出矿井的通风系统设计优化过程，简要分析陈四楼煤矿通风系统优化经验，以期为矿井通风系统改造提供借鉴。

Design optimization of ventilation system after low gas mines changing into coal and gas outburst mines

The reliability of ventilation system for a mine is directly related to ventilation safety and anti-disaster ability. To ensure the safety production，the ventilation system of the mine must be changed with the change of the mine gas level，to meet the new requirements of mine gas treatment，prevention and control. Different level of gas mine for ventilation system requirements are different. System with simple stucture，safe functions，reliable，economic reasonable and appropriate to the level of mine gas and ventilation system of mine safety production，mine sustainable development is particularly important. Therefore，this paper summarized the design and optimization process of ventilation system in Chensilou Coal Mine，this can provide reference for the ventilation system renovation.
