山岭隧洞施工中的通风与防尘

Ventilation and dust control in construction of mountainous tunnels

近年来,随着我国水利发电事业发展迅猛,山岭隧洞急剧增多。山岭隧洞施工过程中的通风与防尘问题严重威胁着施工工作人员的身体健康,同时也是影响施工工期的重要因素,本文介绍了山岭隧洞施工中常用的通风方式及减少洞内粉尘的措施。

In recent years, the businessof water power generation has developed rapidly, followed by a sharp in-crease in mountainous tunnels. During the construction of mountainous tunnels, the problems of ventilation and dust control are great threats to the health of construction workers, which are also the important factors affecting the period of construction. This paper describes the commonly used methods of ventilation and dust control during the constmction of mountainous tunnels.
