Konkola Copper Mines (KCM) has successfully reintroduced raise boring technology at No. 3 Shaft – Konkola Mine in Chililabombwe, marking a pivotal milestone in its journey toward safer, more efficient, and future-ready underground mining operations. This marks the first raise boring operation at KCM in 15 years, underscoring the company’s renewed commitment to operational excellence and innovation.
Raise boring is a modern mechanical excavation method used to develop precise vertical or inclined shafts between underground levels—without the need for blasting. The technique is widely recognized for its superior safety, speed, and cost-effectiveness, making it a critical tool in modern mining operations.
This strategic initiative is being executed in collaboration with TUMI Raise Boring, a globally respected specialist in raise boring technology. The project supports KCM’s production ramp-up strategy to achieve 300,000 tonnes of copper per annum (300KTpa) by 2030—a key target in the company’s long-term growth plan.
In April 2025, TUMI began drilling the first pilot hole at No. 3 Shaft. The reaming of the drain hole commenced in May. These drain holes play a vital role in dewatering previously inaccessible areas, enhancing underground safety, and unlocking additional mining potential. They are instrumental in stabilizing mine conditions and increasing productive capacity.
The successful return of raise boring is not just a technical accomplishment—it represents a renewed momentum in KCM’s underground mining capabilities, enabling the company to sustain and scale its operations for the future.
Malcolm Mewett, Chief Operating Officer at KCM, emphasized the broader significance of this development:
“Raise boring in any mine is critical. It enables escape routes in emergencies, material movement, and most importantly—ventilation for our people. For KCM, these operations are essential as we grow this mine for the future.”
He added that this success lays the groundwork for a series of raise boring projects, aimed at unlocking deeper ore bodies, improving underground access, and advancing KCM’s transformation agenda. The initiative is also a key pillar in KCM’s efforts to modernize operations, reduce environmental impact, and drive long-term sustainable growth.
Konkola Copper Mines (KCM) Plc, a subsidiary of Vedanta Resources Holdings Limited, is one of Zambia’s largest copper producers. It operates integrated mining and processing facilities across Chingola, Chililabombwe, Kitwe, and Nampundwe. Backed by Vedanta’s investment commitment of over $1 billion, KCM is working to unlock key projects such as the Konkola Deep Mining Project (KDMP) and raise copper production to 300,000 tonnes annually by 2030.
