The Regulator launched an investigation after a loader working underground fell about 15 metres through a void, landing on the level below.
The operator was extracting material when the right-hand side of the loader dropped into a void in the floor. The worker exited and immediately notified their shift supervisor. The area was isolated to reassess the situation on day shift. However, overnight the void enlarged and the loader fell into a previously mined stope underneath.
The Regulator is investigating the cause and circumstances of the incident and will explore the mine’s design and approval processes.
Mine operators should ensure all known voids are documented and the process for any designs, including changes, are thoroughly reviewed before plans are approved.
