WE SPECIALISE IN
UNDERGROUND DEVELOPMENT, CONSTRUCTION, VENTILATION
AND MINING SUPPLIES.
Lethithemba Trading (Pty) Ltd share 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. Less demanding 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 is an easy and safe expandable barrier; that is installed without the use of ladders. The Barrier comes in Single and Double frames. It can extend outwards; depending on the Mining width, creating a 0.5m spacing between bags and Pillars at all times.
This zinc type structure can be erected in a single shift.
This timber or steel clad steel structure provides access between two ventilation districts for vehicles and can be mounted in either zinc or cast-A door.
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/blasting work within the ventilation area.
This mobile steel structure can be erected in a matter of minutes to provide safe access across a moving conveyor belt structure.
This is an easy and safe expandable barrier; that is installed without the use of ladders. The Barrier comes in Single and Double frames. It can extend outwards; depending on the Mining width, creating a 0.5m spacing between bags and Pillars at all times.
This zinc clad steel structure provides safe pedestrian access between two ventilation districts without disrupting vent flow on intake and return.
The doors are constructed to the clients requirements in line with
Mine specifications.
This replaces all brick structures by means of a Heavy Duty steel door being casted in it’s place. The Cast-A-Door not only helps with Ventilation but also with storage underground.
This allows for all the brick structures (Sidewalls and Roofs) to be replaced with 30mPa Concrete, allowing a reduction in damages and leakages and increase the strength of the air crossing.
