Explosion Proof Protection Systems for Mines and Tunnels Environments
vehicles for Mining and Tunnelling sectors Ex protected annually
Accidents in tunnels can have serious consequences. When an explosion occurs in an enclosed system, the fire can spread all around rapidly and escape is difficult. Dust, gas or even both, can be present in the tunnel and potentially, they can be the responsible for an explosion.
Miretti Group, through constant research focused on new technologies and innovative solutions, can explosion protects: Multi Service Vehicles (MVS), Dumpers-Wheel Loaders, Excavators, Mixers, Personnel Carriers, Monorail, Drilling Vehicles, TBM, Ambulances, Cranes etc.

The Explosion Proof Protection Group I Class M2 (gas + coal’s dust) with a most temperature of 150° (450° for tunnels) guarantees the machine’s electrical and mechanical protection, motor included, in order to eliminate explosive primer’s risk.
New Ex Systems, Services and Products for Mines & Tunnels “hazardous locations”
Explosion Proof Protection Systems Mines and Tunnels Environments
All products satisfy the requirements for use in environments with presence of gas, flammable powders and coal dusts.
The target is for all contractors and OEM’s equipment manufacturers. All protection systems have to be design around every single machinery trying to keep their performances and reliability identical to the original ones. More and more frequently, OEM’s are looking for competence and experience in this very sensitive sector.
The production range also includes explosion proof sophisticated lighting systems, electricity sub-stations, data transmission and gas detection/monitoring and control systems.
Emission Control Systems for Mines & Tunnels Environments
Miretti can provide a wide range of solutions reducing exhaust pollution from machines/engine which work in mines and tunnels environments.
Miretti also adopts an environmental friendly approach by using gas purification systems for exhaust gases.
Tunnels & Mines Integrated Gas Monitoring System
Miretti can provide Integrated Safety and Security Systems (and not only simple components).
The Miretti Integrated System allows the control and monitoring of the explosive gas in combination with the pollutant substances. Our Systems can control also the tunnel ventilation apparatus.
Miretti can offer the customer a Complete Solution for the Safety and Security Management of the entire working site.
Miretti Monitoring System is supplied, integrated and certified in compliance with the main Worldwide Explosion Proof. It is also possible, on request, to have a Notified Body Approval of the entire Miretti System.
