Abstract

 The new ventilation system for reducing the dust concentration has developing in order to cope with the enlargement of the cross section of the mountain tunnel. Now a new ventilation method called “the dust collection system with air supply and suction” is proposed at various sites. This method is expected large dust collection effect by isolating the dirty and clean air to form the wall of air flow called “Air curtain” by using dust collector near the tunnel face. However, this method is experimental method, it is necessary to clear the optimal design of ventilation system. The indoor wind tunnel experiments were executed the formation characteristic of “Air curtain” by the wind tunnel experiment. And, the possibility of further improvement of dust collection efficiency is examined by in-site experiment at the tunneling site.
