Cementation Africa early dewatering designs: key lessons for mine planners

30 Second Briefing
Cementation Africa is pushing for underground mine dewatering to be designed from the earliest study phases, with hydrogeological investigations embedded in scoping and pre-feasibility work rather than added after shaft sinking. Study Manager Mine Engineering John Goulding stresses that early characterisation of aquifers, inflow rates and pore pressures allows proper sizing and siting of pump stations, sumps and grout curtains, and integration with shaft and decline layouts. For geotechnical and mine planners, this approach reduces unplanned inflows, avoids costly retrofits and supports more reliable ground support and excavation sequencing.
Technical Brief
- Pump station caverns and access drives are dimensioned early to accommodate staged pump upgrades and redundancy.
- Early dewatering design explicitly considers safe access for pump maintenance, pipe replacement and emergency power routing.
Our Take
Cementation Africa’s focus on embedding dewatering into early-stage designs aligns with its shaft upgrade work at Mopani’s Mindola copper shaft, where long-life hoisting and water management performance will be tightly coupled in practice.
Across our database of 1241 Mining stories, Cementation Africa appears repeatedly in technically complex underground work (Mindola, Tharisa’s underground transition, strategic fleet management), so formalising dewatering early on signals an attempt to standardise risk controls across a growing portfolio rather than treating water as a project-by-project add‑on.
The recent strategic ownership transition involving Cementation Africa, Cementation Americas and Terra Nova Technologies suggests that more integrated early-stage design inputs (like dewatering) could become a group-wide differentiator when bidding for deep or high-water-risk underground contracts.
