As Africa’s mining industry moves deeper, targets increasingly complex ore bodies and responds to rising global demand for critical minerals, the role of specialist underground mining contractors has never been more important. Successful project delivery now depends not only on construction capability but also on engineering expertise, technical innovation and the ability to manage risk throughout the mine development lifecycle.
According to Graham Chamberlain, New Business Director at Cementation Africa, mining companies are placing far greater emphasis on partnering with contractors that can deliver certainty on technically challenging projects.
“Today’s mining projects demand considerably more than conventional contracting capability,” Chamberlain says. “Clients are looking for partners with proven engineering expertise, extensive underground experience and the ability to execute safely and efficiently under increasingly demanding conditions. The complexity of modern underground mining means technical competence has become a critical project differentiator.”
Cementation Africa has established itself as one of the continent’s leading underground mining contractors through decades of specialist experience in shaft sinking, mine development, raiseboring and underground mine infrastructure. The company’s integrated approach combines engineering design, project management, construction, mechanical and electrical installations, commissioning and operational support into a single delivery model.
This multidisciplinary capability enables mining companies to reduce interface risks while benefiting from a contractor that understands every phase of underground mine development.
“Underground mining projects are among the most technically demanding engineering undertakings in the resources sector,” Chamberlain explains. “Every project presents unique geological conditions, different mining methods and specific operational requirements. Success depends on developing engineered solutions that are tailored to each project rather than relying on standard methodologies.”
The company’s track record reflects this depth of expertise. Since 2001, Cementation Africa has successfully completed 25 shafts across the continent, including 10 since 2012. During this period, it has sunk more than 10 000 metres of vertical shaft infrastructure, completed over 72 000 metres of raiseboring and drilled 93 holes using the Rotary Vertical Drilling System (RVDS) and accumulated 8.5 million Fatality Free Shifts.
According to Chamberlain, these achievements represent far more than operational milestones. “They demonstrate accumulated technical knowledge, practical experience and the ability to solve complex engineering challenges underground. Every project builds on the expertise developed on previous projects, allowing us to continually refine our methodologies, improve efficiencies and enhance safety.”
As mining operations pursue deeper deposits and increasingly complex developments, integrated project delivery has become an important advantage. Chamberlain says that the company’s engineering, procurement and construction teams work collaboratively throughout the project lifecycle, enabling faster decision-making, improved coordination and greater flexibility when underground conditions change.
“In underground mining, conditions rarely remain exactly as anticipated,” Chamberlain says. “Having engineering, construction and project management expertise working together allows us to respond quickly to changing circumstances while maintaining programme, quality and safety objectives. That integration creates real value for our clients.”
Innovation also continues to shape the company’s approach to underground mining. Cementation Africa continues to invest in advanced shaft sinking methodologies, specialised equipment, digital engineering technologies and modern project management systems to improve productivity, optimise project execution and reduce operational risk.
However, Chamberlain believes that technology alone is not enough.
“Technology is a powerful enabler but it delivers the greatest value when combined with experienced people who understand underground mining. Our strength lies in bringing together engineering excellence, practical construction knowledge and a culture of continuous improvement to deliver predictable outcomes on some of Africa’s most demanding mining projects.”
With global demand for copper, platinum group metals and other critical minerals continuing to drive investment across Africa, Chamberlain expects demand for specialist underground expertise to increase.
“The future of African mining will depend on developing increasingly complex underground operations safely, efficiently and sustainably,” he concludes. “That requires contractors with the technical depth, engineering capability and proven execution experience to deliver critical underground infrastructure with confidence. Cementation Africa has built its reputation on precisely those strengths, and we remain committed to setting the benchmark for underground mining excellence across the continent.”
