COAL MINING AND EXPLOSIVE ENVIRONMENTS

EXPLOSIVE ENVIRONMENTS

(Coal mines, sanitation)

SUB’ROCA offers you a set of skills and services ranging from measurements and ventilation studies to the supply of specific equipment for coal mines: emergency and rescue refuges as well as main and secondary ventilation.

Safety equipment for explosive environments

Because your sites do not always have emergency exits adapted to all reasonably foreseeable risks or disaster situations, it is the responsibility of the operations manager to propose a safe place as close as possible to the work areas.

Thanks to their mobility and modularity, these safety areas, known as rescue chambers, allow you to develop your evacuation plan as excavation progresses.

SUB’ROCA offers a complete range of refuges adapted to the specific constraints of mines with explosive atmospheres. This equipment is therefore non-electrical. These refuges increase the staff’s chances of survival.

With its state-of-the-art technology, the emergency refuge maintains optimal air quality and a pressurised atmosphere over a period of a few hours to a few days (up to 36 hours and more).

VENTILATION STUDIES

MAIN AERATING STUDIES

Site study allowing to validate the conformity both in terms of architecture and means of the site. It integrates the production, geographical and strategic constraints in the short, medium and long term.

SECONDARY VENTILATION STUDIES

Study of specific worksites in dead end. It defines the concept and the means of ventilation to be set up according to the chosen method of digging and pickling. This secondary ventilation study must be strictly applied during the work phase by the site operators. All the secondary ventilation studies are an integral part of the technical ventilation file.

STUDIES AND SPECIAL MEASURES

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

SIMULATION

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