长隧道掘进通风及防尘技术

隧道施工,尤其特长大隧道施工,搞好通风防尘是改善洞内施工环境,提高工作效率的一个重要措施,是采用无轨运输方式,更要全力搞好。通风防尘主要解决两方面问题,一是有毒气体,主要来源于爆破炮烟和内燃机械废气;二是粉尘,主要来源于洞内开挖爆破和机械作业扬起的灰尘等。

Long Tunneling Operation Well Ventilated and Dustproof Technology

The tunnel construction,the special skill big tunnel construction,does well ventilates dustproof is especially improves in the hole to construct the environment,raises the working efficiency an important measure,especially selects the flexible transport method,must do well with allone's strength.Ventilates dustproof mainly solves two aspect problems,one kind is the noxious gas,important source in demolition artillery smokeand internal combustion mechanical waste gas;Another kind is the dust,the important so...
