A High-level Overview of Different Shaft Linings

The lining of a shaft performs several functions including stabilising the walls of the shaft, providing structural support to the guides for the conveyancing systems, as well as to optimising air flow for the mine ventilation design. Therefore, selection of the most appropriate type of shaft lining needs to be considered during the design phase.
