Enhanced Mining Safety with Stainless Steel Split Sets
Mpumatech has introduced stainless steel split sets to underground mining environments, marking a significant advancement in roof support technology.
Mpumatech Sales and Business Development Director Andrew Ioannou says: “Our stainless steel split sets, made from corrosion-resistant stainless steel, are designed to enhance safety and efficiency in underground mining operations, offering a long-lasting solution that significantly reduces maintenance and operational downtime”.
Understanding split sets
A split set, or friction anchor, is used in underground mining to provide temporary or permanent support in excavation roofs or walls. It is a cylindrical steel tube with a longitudinal slot allowing expansion when inserted into a predrilled hole. This expansion creates frictional anchoring,
which stabilises underground excavations, especially in soft or unstable rock formations.
Innovative material
Stainless steel split sets have the same load-bearing capacity and elongation as traditional mild steel versions but with additional benefits. The corrosion resistance of stainless steel makes it ideal for harsh underground environments, ensuring long service life and reducing the need for frequent replacements. Mpumatech also customises split sets to meet specific mining requirements, optimising performance while maintaining compatibility with existing infrastructure.
Life cycle cost
The life cycle cost of durable stainless steel split sets is also competitive when compared to galvanised steel options. While the initial cost of stainless steel is higher, its extended service life and reduced maintenance needs lead to longterm savings. Galvanised steel requires regular maintenance and replacements, which can add to operational costs over time.
Localisation potential
Mpumatech’s stainless steel split sets have significant localisation potential in South Africa, particularly through collaboration with Columbus Stainless. This partnership could enhance domestic production, create jobs and reduce import dependency. Local sourcing also supports environmental sustainability by lowering carbon emissions associated with transportation.
Market growth
Durability and corrosion resistance position Mpumatech’s product for market growth, particularly in Australia. Ongoing trials comparing stainless steel with galvanised steel in mining environments are expected to highlight the advantages of stainless steel split sets. “This product is a game changer for the South African mining sector, which has long struggled with issues of durability and cost in challenging underground conditions,”
says Ioannou. “By introducing stainless steel split sets, we’re offering a solution that not only enhances safety and efficiency but also supports local manufacturing and reduces long-term operational costs. This innovation comes at a critical time, providing the industry with the resilience it needs to overcome current challenges and sustain its future.”
