TRG for fans at underground coal mines

We have published a new Technical Reference Guide (TRG): Main fans, booster fans and auxiliary fans at underground coal mines. (PDF, 700.31 KB)

This TRG provides information that will assist underground coal mine operators to minimise risks to health and safety relating to the use of ventilation fans at underground coal mines. It supersedes Mining Design Guideline (MDG) 3 and was developed following a review of MDG 3 in 2020, followed by targeted stakeholder consultation in early 2021.

A new booster fan design order which references this new TRG will be published in early 2022. A suitable transition period will be included in the new design order to enable industry time to prepare for the new standard.
