Abstract The large amount of dust that emerges during long tunnel construction is harmful to the health of workers. To improve dust-removal technology during tunnel construction, the mechanism of dry dust-removal technology is analyzed and the technology and performance of a dry dust-removing machine are discussed in this paper based on research of state-of-the-art dust-removal technologies at home and abroad. During construction, the dry dust-removal machine is placed 30m behind the tunnel face where the dust concentration is higher. Dust-removal is mainly focused on the construction sequences of blasting and shotcreting, and its effects are significant. This study shows that the installed ventilation system can exhaust noxious CO gases out of the tunnel and that the dust-removal machine can decrease the concentration of dust from 75mg/m3 to 3mg/m3 after two minutes of operation. The problem of dust concentration exceeding acceptable standards during long tunnel construction can be successfully solved by using a dry dust-removal machine in combination with a jet flow ventilator.
