VENTILATION SYSTEMS FOR UNDERGROUND MINES AND QUARRIES

Ventilation systems

Ventilation is an essential function in underground mines. It ensures the health and safety of workers and the productivity of the operation.

SUB’ROCA designs high-performance ventilation systems to ensure the smooth running of the mine.

Whether it concerns the main ventilation of the mine, or the secondary ventilation of the excavation fronts, we are able, thanks to our software and our experience, to guide the operator in his choices and to propose a solution that is economical to operate while ensuring the safety of the miners.

SUB’ROCA offers you a whole range of silent axial fans, which can be equipped with skid frames and connected to flexible PVC ducts.

Main ventilation

Main fans for the main ventilation system designed and installed taking into account the ventilation requirements related to the mining methods and design of the mine.

Our software enables us to analyse the impact of ventilation on the meshed networks and to optimise the equipment to ensure performance and energy savings.  

Secondary / auxiliary ventilation

Secondary fans allow the air flow to be brought and controlled to the work area.

SUB’ROCA designs its secondary fans on general principles of robustness, mobility and performance.

Together with you, we define the necessary flow rates and the most strategic duct diameters to ensure reduced energy consumption.

Various configurations

We are able to design fans ranging from single stage (1 stage) to multi-stage (up to 4 stages) adapted to the constraints and phasing of your site based on the following characteristics: 

  • Casing made of S235JR steel with galvanised or epoxy paint finish.
  • The motors supplied have, depending on the case, a supply voltage of 230/400V or 400/690V (230V single phase/1000V or other on request).
  • Our fans are equipped with support feet as standard, but can be optionally mounted on fixed or mobile chassis (wheels, sledge/skid, etc.) for ease of movement.
  • The propellers are made of blades whose material varies according to the application propylene, glass-fibre reinforced propylene, aluminium, antistatic plastic. Thanks to our high quality materials and our design software, we can provide you with the propeller best suited to your constraints. Being at the forefront of propeller technology is part of our commitment.

Ventilation ducts and networks

Flexible spiral ducts, more commonly known as « Spiragaines » are ducts that allow a fluid, in this case air, to circulate, which may be loaded with pollutants, dust or gas. They can be used for either blowing or suction (in overpressure or underpressure) and can be connected by different technologies (belts, straps, zip,…).

They are originally produced with 550g/m2 PVC, but can be produced with PVCs from 300 to 1000g/m2 on request and are packaged in sections of 5, 10, 15 or 20 metres.

Smooth flexible ducts, more commonly known as « Ventubes », are ducts for the circulation of a fluid, in this case air, which can be loaded with pollutants, dust or gas. They are used for blowing and can be connected by different technologies (belts,
straps, zip,…).

They are originally produced with PVC of 550g/m2, but can be produced with PVC from 300 to 1000g/m2 on request. They are packaged in sections of 5, 10, 15 or 20 metres. They can also be produced on the basis of several tens, or even hundreds of metres if a sheathed cassette is used, particularly for digging work by tunnel boring machines.

Ventilation walls

Mur ventilation

In addition to designing multi-stage fans, we are able to design customised ventilation solutions for your underground projects such as ventilation walls. 

Accelerators for open lanes

Due to the geometry of the galleries and mesh networks, it can be difficult or even impossible to guide the air to specific locations. It may be possible to favour the air path with Jetfan or also called accelerator.

SUB’ROCA has been able to make use of its know-how from the Charbonnages de France to design Jetfans mounted on fixed or mobile frames that can be easily moved to adapt the air path.
