PEX Expandable Sheet
Pretensioned support element designed for underground mining.
When injected with high-pressure water, it expands uniformly,
providing stability and reinforcement in critical areas.
PEX FORMIN Expandable Sheet: Effective Support Solution for Underground Mining
At FORMIN, we specialize in providing advanced solutions for underground mining projects. Our PEX expandable plate is a pretensioned unit used for supporting tunnels and galleries, working together with the Wood pack to prevent rock falls in underground mining operations.
What is the PEX Expandable Sheet?
The FORMIN PEX expandable sheet is a pretensioned support system designed to strengthen underground mining structures.
It is installed once three-quarters of the total height of the structure is reached, fully covering the area with the Wood pack elements.
The base where the unit is placed must be prepared as a bed, allowing the plate to inflate uniformly when injected with high-pressure water, exerting even pressure across its entire surface and ensuring reliable support throughout the area.
Benefits of the FORMIN PEX Expandable Sheet
High load capacity
The FORMIN PEX expandable plate can support up to 160 tons, providing excellent strength and stability in underground structures.
Easy and quick installation
Using high-pressure pumps, the plate expansion is carried out quickly, without the need for additional chemicals.
Adaptability to different shapes and sizes
The pretensioned unit is available in various configurations, such as rectangular, square, oval, and triangular, making it perfect for different support applications.
Vibration resistance
The plate is highly resistant to vibrations caused by blasting, thanks to the high confinement pressures it withstands.
- Tunnel and underground gallery support.
- Prevention of rock falls in underground mining operations.
- Reinforcement of temporary structures in mining projects.
- Recovery of pillars and strengthening of other critical areas in underground mining.
