Good ventilation is the prerequisite for the safe construction of long tunnels and is also the guarantee measures for good construction progress and good works quality. In the paper, the performance parameters of ventilation ducts are analyzed, the influence of ventilation ducts on the ventilation energy consumption and ventilation fan selection is obtained, and the cost efficiency of the ventilation equipment and ventilation operation is analyzed, so as to achieve energysaving and environmentfriendly ventilation for longdistance deadend tunneling. Conclusions drawn are as follows: 1) Instead of ventilation fans made by foreign companies, highquality ventilation ducts should be used; 2) The tunneling contractors should unite largescale domestic ventilation fan manufacturers and ventilation duct manufacturer to manufacture highquality ventilation equipment, so as to achieve energysaving and environmentfriendly tunneling ventilation. 
