Mines & Quarries

PARTNAIR INDUSTRIES makes its experience and technical expertise from Charbonnages de France available to you.

The world of mines and quarries is the historical heart of the company.

We offer a range of skills and service from the measurements and the studies of the ventilation to the supply of specific equipment for your underground site: refuge chambers, main or secondary ventilation.

Safety equipment for underground mines and quarries 

Because the operating sites do not always have emergency exits adapted to all reasonably foreseen risks or disasters, it is the responsibility of the Operations Manager to provide a safe area the closest possible from the work area.

These safety areas called refuge chambers allow, thanks to their mobility and modularity, your evacuation plan to evolve according to the progress of the excavation.

PARTNAIR INDUSTRIES offers a complete set of refuge chambers adapted to technical and economic constraints of the mining environment.  These refuge chambers increase the chances of survival of the staff.

Equipped with the latest technology, the refuge chamber maintains an optimal air quality and a pressured atmosphere over a period of a few hours to a few days.

Ventilation ensures the renewal of air in underground quarries and mines.

PARTNAIR INDUSTRIES designs ventilation systems for venting gases and dust, in order to guarantee the health and safety of the staff and to increase the productivity of your excavation work.

Our ventilation systems can be connected to the site’s security supervision. This increased ventilation includes monitoring equipment to perform predictive maintenance

Ventilation / Aeration studies

Main ventilation studies

The study of the main ventilation is a site study to validate compliance in terms of both architecture and means of the site. It takes into account the production, geographical and short, medium and long-term strategic constraints.

This ventilation study shall be regulated by/based on a technical file designed to identify all direct or indirect ventilation risks and to include action plans with a view to ensuring the health and safety of the workers.


A study of main ventilation meets several criteria:

  • Inventory of the architectural data of the site
  • Drafting of the strategic development plan at 5, 10, 15.. and even 30 years
  • Inventory of productive equipment and regulatory constraints throughout the life of the project
  • Numerical modelling of the site using aeraulic in mesh networks calculation software« AERO© »
  • Proposals of concepts of main ventilation/aeration for air renewal adapted to the simultaneity of the work, framed by secondary aeration/ventilation studies.
  • Recommendation on the necessary equipment
  • Study Report

Studies of secondary ventilation 

The secondary ventilation study is the study of specific dead end workings. It defines the concept and means of ventilations to be used depending on the method of excavation and marinating chosen. This study must be strictly applied during the work phase by the site operators.

All secondary ventilation studies form an integral part of the technical file.

Studies and specific measures

These studies concern both specific problems and those involving the presence of fires in a mesh network.

  • Study of piping systems : dimensioning study of piping networks for hydraulic and compressed air transmission and distribution.
  • Study of air conditioning systems : modelling of existing climatic conditions leading to a sizing study of the necessary refrigeration facilities.
  • Study of filtration systems (dust removal) : sizing study of the filtering system using innovative and adapted technologies.

Fire evacuation studies

On the basis of numerical modelling carried out during the main and secondary ventilation studies, we simulate the presence of fires and their consequences on the atmosphere and the evacuation of workers.

The simulated scenarios correspond to the risk analysis that we will carried out jointly with you and which very frequently includes the areas of entrances and exits of the site, the mechanical workshop of the site, the excavation/drivage galleries and the explosive deposits.

The type of fire simulated will be adapted to the surrounding conditions and hazards.

Example: the fire of an operating machine filled with fuel in one of the galleries, or the fire of a machine under maintenance in the mechanical workshop.

The results obtained validate or not the natural excavation/drivage gallery/route, the need for refuge chambers and their locations where appropriate.
