MINAX 80/4.6 was build in this tunnel to provide the best dynamic ground support.

MINAX® 80/4.6 is the solution when it comes to high demands in ground support. Wherever conventional ground support elements come to their limits, MINAX 80/4.6 will provide the best dynamic ground support to protect from rockburst and bigger ground failures.
Various Tests conducted by the Western Australian School of Mines (WASM) and at our dynamic test site in Walenstadt have shown that high-tensile MINAX® mesh with a wire tensile strength of at least 1,770 N/mm2 can withstand substantially higher static and dynamic loads than conventional reinforcement nets. This also enables higher levels of rockburst energy to be absorbed.

Benefits

High-tensile steel wire

High-tensile steel wire

For high load capacity: Both static and dynamic capacities (e.g. while blasting) are higher compared to other surface support meshes/nets.

Balanced stiffness

Balanced Stiffness

Very high load capacities (both static and dynamic) with optimal deformations, not endangering tunnel clearance.

Rhomboidal chain-link structure

Rhomboidal chain-link structure

For easy handling and storing: Manual and mechanized installation by unrolling with any mechanized technology.

Low weight

Lightweight

For fast installation: Very light relative to its strength due to the high-tensile wire. This makes manual or mechanical installation very easy and improves the occupational health and safety.

Knotted ends

Knotted ends

For maximum stability at the edges: Profit from minimized overlapping, optimized number of rock bolts and no sharp edges.

Cutting edge corrosion protection

Whether hot dip galvanized, SUPERCOATING®, stainless steel: After our analysis of the environmental conditions in your mine, we offer the corrosion protection solution, according to your specific needs.
