Ventilation in underground mines and tunnels

In closed environments like mines and tunnels, ventilation is crucial to maintain sufficient quantities of oxygen and keep air free of dust, toxic gases and vapours. We have produced guidance that outlines the ventilation needed for different types of mining and tunnelling operations.

This approved code of practice outlines the ventilation needed for different types of mining and tunnelling operations. This is intended to provide practical guidance to anyone engaged in mining on how they can meet health and safety obligations around ventilation.
