In order to address the air quality issues in underground construction sites, specific ventilation systems are required to meet the requirements of the law.
A tunnel or mine ventilation system during the excavation phases is an articulated system composed of different parts: fans, distribution ducts, dedusting systems, and regulation and measurement systems.
At Montes, we are specialists in the design and production of dedusting systems
made to customer specifications for any type of pollutant, including in explosive environments (ATEX M2 certification
) and for conventional (roadheaders, hydraulic hammers, explosives
) or mechanized (TBM
) excavation techniques.
Conventional excavation dedusters
are air filtration systems capable of operating autonomously in support of primary ventilation systems. This solution ensures maximum flexibility and the proper treatment of all types of dust. Conventional excavation filtration systems are mobile and can be placed in strategic points at the site for effective dust collection straight from the source.
Mechanized excavation dedusters
are installed on TBMs to dedust the air drawn in by the rotating head and related equipment. They are custom-designed to fit perfectly into the backup section on the TBM and connected to the air intake and discharge piping.
The solutions available to treat any type of dust (silica, gypsum, limestone, asbestos, coal, etc.) in tunnel excavation and mining are:
- TBM (Tunnel Boring Machine) dedusters to be mounted on the backup
- Dedusters for conventional excavation methods (roadheaders, hydraulic hammers, explosives)
