富含瓦斯隧道的施工通风及安排防护

The Ventilation in the Rich Gas Tunnel under Construction and Technology of Safety Protection

瓦斯隧道施工，预防瓦斯和各种有害气体，保证施工安全应放在首位，而最经济最有效的技术措施，就是采取合理的通风方式。本文结合华蓥山隧道瓦斯含量高、压力大、隧道断面大的特点，研究其施工通风系统设计方法及综合安全防护技术，并介绍了初步应用效果。

Combined with Huaying Mountain tunnel's features of rich highaspressure gas and large section,the report researched the method of ventiltion in the tunnel under construction,amd the comprehensive technology of safety protection,and introduced tentative good results of appling the technology.
