Ex Mines & Tunnels Underground

Explosion Proof Heavy Duty Solutions typically used
for Underground field and in compliance with
Group I M2 (Atex Directive)

Accidents in tunnels can have serious consequences. When an explosion occurs in a closed system, the fire can spread rapidly around and escape is difficult. Dust, gas or even both may be present in the tunnel and potentially be responsible for an explosion. The high temperature surfaces of diesel engines or electric motors, hot exhaust gases and sparkling electrical appliances, by their very complexity, sometimes represent an obstacle in the way of protection.

Miretti Explosion Proof protects several special vehicles, specialist machines and large earthmoving machinery, Heavy Duty Solutions typically used in major construction sites, in underground operations, in mines and in tunnels:

Multi Service Vehicles (Msv) | Personnel Carriers | Monorail | Dumpers | Wheel Loaders | Ambulances | Drilling Vehicles | Tow Tractors | Access Platforms | Scissor Lifts | Boom Lifts | Utility Vehicles | Excavators | Mixers | Cranes | TBM (Tunnel Boring Machine) | Mining Equipment & Components & Enclosures | etc…

Projects like these have been always a challenge.

Since 1973, the Miretti Group has extensive experience in the mining and tunneling sector, therefore it is able to immediately understand the needs of the end user. When “Hazardous Areas ” comes, Miretti engineering team can offer multiple solutions.

The realization of Large Construction Sites or State Strategic Works implies having to operate in dangerous areas. The construction of tunnels involves important and colossal underground excavations. There is a real risk of running into dust and gas pockets, in operating with large handling machines in underground or proxemic tunnel areas, such as the better-known firedamp, which can generate dangerous explosions with serious damage for the workers, the construction site itself and the surrounding natural habitat.

    The collaboration with the “Strategic State Works” department, where Miretti still plays a pivotal role as the primary supplier, working in partnership with major players in the Construction and Major Infrastructure sectors began in the 1980s.

    In the 1980s, Miretti ventures into earth-moving and begins designing explosion-proof solutions for the large machines used in National Strategic Projects and Construction Sites. This means reliability in explosion-proof conversions for vehicles that work in underground environments such as mines and tunnels. Each equipment upgrade requires a deep knowledge of the latest Atex regulation and a thorough understanding of both mechanical and electrical method of protection. All these protection systems must be designed around each single machine, trying to maintain performance and reliability identical to the original ones.
