PECULIARITIES OF PROVIDING AERODYNAMIC SAFETY AT THE CONSTRUCTION AND OPERATION OF VEHICLE TUNNELS
The principles of ensuring aerodynamic safety at construction and operation of underground constructions of vehicle tunnels are formulated. Constructive and functional differences of fans -ejectors, applied in potash and the bauxite mines, from the jet fans used for ventilation of vehicle tunnels are noted. The technical solution under application of fans - ejectors for ventilation of vehicle tunnels after end of their driving during construction and erection work is proposed.
