Analysis on the dust prevention mechanism of air curtain in fully mechanized excavation tunnel

Abstract Aiming at reducing the dust pollution during the tunneling process and improving the application efficiency of air curtain dust prevention technology, according to the changes of radial jet velocity (v r), axial extraction velocity (v e) and extraction distance (L) in the formation process...
