Mancala traditional shaft sinking capabilities have been utilised in numerous applications including:
- Pre sinks in areas of poor ground conditions prior to full shaft excavation by other method
- Underground coal storage silos
- Complete shaft excavation up to 6.0m diameter and 250m depth - concrete or fibrecrete lining
- Ore pass refurbishment and lining by shrinking
The Future Developments:
- Non-entry 14m diameter to 500m depth
- Mancala in conjunction with Herrenknecht is developing methodologies to reliably sink and concrete line shafts at productivities which far exceed existing technologies
