The Resources Regulator in NSW has launched a causal investigation into factors that led to an underground mine fire at Perilya Southern Operations, Broken Hill, NSW, on 12 January 2025.
The Regulator’s investigation will consider if a polyurethane ground stabiliser self-heated after being applied by workers who were undertaking ground support and remedial work in an isolated underground area.
Underground workers identified fumes and vapor while applying the product. The workers successfully retreated to fresh air where they remained until it was assessed as safe to leave the mine. All workers were safely removed from the mine and there were no injuries reported by the mine operator regarding this incident.
The Regulator has provided some preliminary recommendations which can be found in the Investigation Information Release.
Following the completion of the investigation, an investigation report will be published.
