Zibulo North Shaft decline: mechanised development lessons for mine engineers
Reviewed by Joe Ashwell

First reported on International Mining – News
30 Second Briefing
Cementation Africa has completed Thungela Resources’ Zibulo North Shaft decline under demanding underground conditions, using a continuous miner for a critical phase of advance rather than conventional drill-and-blast. Project Manager Peter Mazibuko credits the team’s underground coal expertise and close collaboration with the client for enabling safe deployment of the continuous miner in a constrained decline environment. For mine developers, the project signals growing confidence in mechanised decline development to accelerate schedules where geology and layout permit.
Technical Brief
- Coal-specific ground control expertise from Cementation Africa’s underground teams underpinned safe sequencing and support installation.
- Ventilation and gas management had to be adapted for mechanised cutting in a confined decline geometry.
- Equipment access and egress plans were revised to maintain emergency escape routes during continuous miner operation.
- Operator training focused on coal cutting hazards, machine visibility envelopes and proximity to unsupported ground.
- Project learnings are expected to inform mechanised decline risk assessments and method selection on other coal shafts.
Our Take
Across recent coverage, Cementation Africa repeatedly appears on technically complex underground work – from Mindola shaft upgrades in Zambia to Tharisa’s Bushveld transition – signalling that Zibulo North Shaft fits a portfolio of high-risk, high-skill contracts where safety performance is a key differentiator.
Cementation Africa’s push, in a July 2026 article, for earlier integration of dewatering and hydrogeology into mine studies implies that lessons from Zibulo North Shaft could feed back into front-end design standards for future underground projects in the region, particularly around water management and ground control risk.
