UNDERGROUND VENTILATION STRUCTURES
Mantella Trading 310 (Pty) Ltd own patent 98/7391 for Roll-A-Wall Ventilation Stoppings. This industry proved stopping system can be erected by a team of four trained people in under two hours.
This modular system holds many advantages to clients by improving rate of construction thus reducing down time due to ventilation problems and less demand on the transport system because of the light weight and bulk of the components.
Other products have been developed to be used in conjunction with Roll-A-Wall Stoppings such as:
This zinc clad steel structure provides pedestrian access between two ventilation districts.
This self closing ventilation pressure relieve structure should be used to reduce the amount of damage caused to the ventilation stoppings due to a goaf within the ventilation area.
Heavily constructed steel doors to ensure the safety of the occupants in the rescue bay.
