Longwall operations have been temporarily suspended at a Central Queensland mine following a frictional ignition event.
No workers were injured when the incident occurred in the longwall at Kestrel South underground mine near Emerald on Sunday afternoon.
A frictional ignition refers to a hot spot or spark that ignites a flammable concentration of methane.
A Kestrel Coal spokesman said the Queensland Mines Inspectorate was aware of the incident.
Resources Safety and Health Queensland was contacted for comment.
“Kestrel Coal elected to temporarily suspend longwall operations while an internal investigation was conducted into the cause of the incident,” the company spokesman said.
