| Abstract: | Yangbajing No.1 tunnel is the longest tunnel on Qingzang railway and situated on Qingzang plateau,the ridge of the world.Under the condition of the operation of diesel engines and trackless haulage,the construction was speeded up by means of the proper selection of construction ventilation,the reform of ventilation fans,the in-situ management of ventilation,oxygen supply in the tunnel,dust collection etc.The practice can be taken for reference by similar projects. |
