Abstract:

  Because of the high altitude, low air pressure and low air density in plateau area, the performance of the ventilators in plateau area is different from that in plain area. The factors that influence the air pressure and air volume of ventilators in plateau area are analyzed. Solutions for the performance changing of ventilators in plateau area, appropriate ventilation methods and assistant measures for tunnel construction ventilation in plateau area also presented.
