What is shaft lining?

Shaft lining is a technique used to reinforce the interior walls of a vertical tunnel or shaft. This is necessary in mining and excavation projects to prevent the walls from collapsing and potentially endangering workers or equipment.

Shaft lining typically involves installing steel or concrete supports inside the shaft, either by drilling or affixing them to the walls. The lining can be temporary or permanent, depending on the nature and duration of the project.

Some common materials used for shaft lining include steel arches, concrete segments, and polymeric liners. These materials provide added strength and stability to the walls of the shaft, reducing the risk of cave-ins or collapses.

Proper shaft lining is an important safety measure in any vertical excavation project. It helps to ensure the well-being of workers and the integrity of the surrounding environment.
