Stretched Metal Mesh: A Seismic Support Solution for Gold Mine Tunnels in New Zealand
2026-05-07
Situated within the Pacific Ring of Fire, New Zealand faces geological challenges in gold mining. Stretched metal mesh, manufactured from high-tensile steel, forms a ‘flexible-rigid’ support system in conjunction with anchor bolts: when seismic stress is released, the mesh absorbs energy through elastic deformation, preventing sudden tunnel collapse; its lightweight design reduces underground transport loads, making it well-suited to the deep mining operations characteristic of New Zealand’s gold mines. It creates a seismic safety barrier for miners, minimising the impact of geological activity on mining operations.
