AECI Mining’s 20 years in the DRC: drill‑and‑blast lessons for open‑pit engineers

30 Second Briefing
AECI Mining Explosives has marked 20 years of continuous operations in the Democratic Republic of the Congo at DRC Mining Week 2026 in Lubumbashi, emphasising its role as a long-term strategic partner to local copper and cobalt producers rather than a transactional explosives supplier. Over two decades the company has embedded blasting services, on-site technical support and supply-chain capability into major operations, adapting its product mix to changing pit geometries and higher stripping ratios. The anniversary signals sustained demand for integrated drill-and-blast solutions and stable emulsion supply in one of the world’s most active open-pit mining regions.
Technical Brief
- On-the-ground teams provide blast design, timing, and fragmentation optimisation aligned with each pit’s geotechnical model.
- Emulsion and accessories are supplied via in-country logistics chains, reducing border-crossing delays and stock-out risk.
- Technical personnel are embedded at mine sites to adjust charge densities and patterns as ore hardness varies.
- Long-term presence enables continuity of blast parameters as pits deepen and wall stability requirements tighten.
- Local workforce development includes training blast crews in safe handling of bulk emulsions and initiating systems.
- Close integration with mine planning teams allows drill-and-blast schedules to track rapid production ramp-ups.
- Experience in wet-season conditions informs water-resistant charging practices and bench drainage considerations.
Our Take
AECI’s 20-year explosives presence in the DRC, centred on hubs like Lubumbashi, positions it as a relatively mature African platform compared with its newer roles in markets such as Australia, where our coverage shows its Thiess joint operating agreement only runs to 2030.
The timing around DRC Mining Week 2026 indicates AECI is using the event to lock in or extend long-cycle supply relationships, similar in structure to the multi-year blasting services arrangements seen in the Thiess–AECI agreement in Australia.
