Appin Mine Twin Ventilation Shafts
pitt&sherry were engaged to ensure reliable and adequate ventilation air supply to personnel working underground.
Our Project Goals
We're supporting South32 in the planning, design and construction stages for two new ventilation shafts to extend the mine life beyond 2040.
What we did
Scoping, pre-feasibility and feasibility geotechnical and mining services for the two shafts. Provided specialist geotechnical and shaft mining technical advice to the selection of a suitable location for the shafts and appropriate excavation methodology for the diameter, depth and ground conditions. Geotechnical investigations and assessments of subsurface conditions for shafts and shaft infrastructure. (Subsurface investigations, factual and interpretive geotechnical assessments, design input to infrastructure design).
Design certification of shaft collars and lining for both shafts. This involved independent verification and design.
Project Outcomes
Project is under construction, with certification provided for VS8 collar and liner and work ongoing for VS7.
