Dust Suppression in the Main Tube

A2 Second Tube Gotthard 2023

We implemented a double dust suppression system for the first section of the motorway tunnel excavated with traditional blasting technology.
The first one traps the dust and drags it into the ground during general processing, the second one is activated during blasting and allows the dust and gases generated by the explosion to be quickly abated.
