摘　　要：对于地下洞室群施工中的通风问题,必须解决好稀释炮烟、各种燃油机械排出的废气及除尘等,以创造出良好的地下施工环境。地下洞室群的结构特点及施工过程中的复杂性决定了地下洞室群通风问题的特殊性。阐述了针对地下洞室群施工过程的不同阶段设计的不同的通风散烟系统并予以实施,不但解决了高效通风问题,而且在一定程度上优化了地下洞室群的开挖程序。For the ventilation in the construction of underground caverns,it is necessary to solve the problems of dilution of blasting smoke,exhaust gas and dust removal from various fuel-fired machinery,so as to create a good working environment for underground construction.Nevertheless,the specific ventilation issue of the underground cavern group is influenced by the distinctive structural features and intricate construction procedures associated with it.This paper presents various ventilation and smoke dispersion systems designed for different stages of the underground caverns construction process,taking into account the calculation of the theoretically appropriate ventilation volume.These systems aim to not only achieve efficient ventilation but also enhance the excavation procedures of underground caverns to some extent.
