A dangerous incident occurred at North Wambo Coal Mine on 3 May 2020, which resulted in the partial collapse of a ventilation shaft.

The failure of an underground bulkhead seal during shaft boring operations led to a surface sinkhole being created beneath a drilling rig, causing workers to take evasive action and the drilling rig to partially descend into the void. No one was injured.

The NSW Resources Regulator has issued an Investigation information release (IIR20-07) into the incident today and have begun an investigation to determine the cause and circumstances of the incident. The mine operator, relevant contracting companies as well as the site and industry safety and health representatives are participating in the investigation.

This information has been published to draw attention to the occurrence of a dangerous incident in the mining industry. Further information may be published as it becomes available.
