Underground Mine Development Infrastructure and Mechanised Lateral Drilling
Redpath Africa Limited deploys specialised underground development systems to optimize mechanised lateral advance rates for regional mining operations.

Redpath Africa Limited and Redpath Australia Limited cooperate to execute complex underground development projects across African mining operations. This cross-entity partnership combines regional shaft-sinking and raiseboring resources with specialised high-speed mechanised lateral development systems.
Operational Challenge and Technical Rationale
Transitioning open-pit operations into underground production requires diverse engineering disciplines, including portal construction, civil ground stabilization, electrical network installation, and lateral drilling. Underground mine development demands both extensive regional mobilization and specialised mechanized tooling. To address these multidisciplinary demands without fragmenting contractor management, Redpath Africa Limited accesses the technical methodologies and mechanical competencies established by Redpath Australia Limited. This structure replaces single-scope contracting with an integrated delivery framework across the project lifecycle.
Technical Solution and Engineering Division
The combined engineering framework encompasses vertical and horizontal excavation:
- Redpath Africa Limited manages shaft sinking, raiseboring, site infrastructure, blasting protocols, and regional logistics.
- Redpath Australia Limited provides technical protocols and equipment configurations for high-speed mechanised lateral development.
Operational safety and mechanical stabilization utilize engineered rock bolts, shotcrete lining, and industrial automation to ensure ground support integrity during high-speed excavation cycles.
Implementation and Field Results
The integrated model was implemented at the Mogalakwena Mine in Limpopo, operated by Valterra. The project scope required the construction of portal entries, surface infrastructure, electrical substations, and a 3,000-metre exploration decline.
By integrating specialized lateral advance methods, the operational teams achieved a monthly advance rate of 367 metres under sustained ground-support conditions. At the Maseve Platinum Mine, Redpath Africa Limited functioned as the principal general contractor, managing underground civil works, structural engineering, and technical development routines.
Regional Target Applications
The operational model targets hard-rock extraction environments across southern and central Africa, including projects in Namibia, Botswana, Zimbabwe, the Democratic Republic of the Congo, and Tanzania. The combined system applies directly to open-pit operations undergoing transition to deep-level underground shaft and decline networks. Technical services and equipment integration were recently highlighted during industry technical sessions at the Ngezi Mining and Technology Exhibition in Zimbabwe.
Technical and Economic Value
Project scheduling and capital utilization represent the core focus of the system. Rather than optimizing exclusively on a contractor cost-per-metre basis, the combined approach targets accelerated access to ore bodies, lowering overall capital costs through standardized lateral and vertical advance rates.
Stuart White, Managing Director of Redpath Africa Limited, noted: "Whether it is shaft sinking, raiseboring, or development, we do not do a lot of mining production really per se. Most of what we do is construction-related, which is important as we seek to reposition ourselves around underground mine development."
