1 Ventilation System in Tunnel during Construction Works
نویسنده
چکیده
Preface Construction works always involve danger and their environment is not always clean. In case of tunnelling works, especially in tunnels to be constructed with the drill and blast method, the problems on the safety and health such as the ones by dust and poison gas are serious subjects. This paper discusses the principle of ventilation system in tunnel during construction to provide good environment for tunneling works.

Preliminary Ventilation and Cooling during the Construction of the Brenner Base Tunnel
With a length of more than 55 km, the Brenner Base Tunnel (BBT) connecting Austria and Italy will be one of the world’s very long tunnels in the future. During the construction phase, climatic conditions need to be maintained fulfilling the occupational health requirements, assuring the functionality of the machinery and allowing the intended construction processes. In view of the extended cons...
متن کاملApplication of cut set method to reliability evaluation of mine ventilation networks
Providing a fresh and cool airflow in underground mines is one of the main concerns during mining. Destruction of support systems, the presence of undesirable objects in the airway and distortion of airflow are the parameters involved that would result in pressure loss, which would affect the ventilation network. There are a lot of research works about the ventilation network planning that cons...

Knowledge of the airflow distribution inside a Tunnel Boring Machine (TBM) can create a safe working environment for workers and machinery. The airflow quality and the related mass flow rate in the ventilation system should be sufficient to dilute gases and remove dust inside the tunnel. In this work, airflow distribution in the single shield TBM tunnel was studied using computational fluid dyn...
