Technical Paper


Concerning human health and safety, more studies should be taken place on the impact of dust movement in the tunnels construction. In the case of large cross-section tunnels driven by boom-type roadheader, dust removal efficiency of the ventilation system is essential for safety protection in tunnels. For the first time, to adapt the larger cross-section tunnels, the following ventilation system has been proposed, and the feasibility has been proven by the comparison results of CFD numerical simulation between large and small cross-section tunnels. Comparisons of removal effect for different cutting point have been made, and the adjustment direction to better removal effect has been summed up. In addition, the two adjustment strategies have been presented and compared within actual working conditions. The results indicated the best parameters range of following ventilation system refers to distance and airflow ratio. The data about dust concentration on different height plane are meaningful for further study into dust removal in large cross-section tunnels, and the rules could be applied in other larger cross-section tunnels.
