BHP Billiton has evacuated its Perseverance nickel mine following a rock fall incident.
The miner stated that the incident at its underground mine was caused by a seismic event yesterday, according to the ABC.
No one was injured in the event.
While the evacuation was stymied by a power outage, all miners still managed to safely leave the site.
The mine, located near Leinster, has a history of rock falls.
In 2009 the mine was nearly closed by the WA state mining engineer due to a series of rock fall incidents within a short period of time.
The two incidents saw one miner injured when a piece of rock hit him in the head, and another mine trapped in the same rock fall event.
Earlier this month another worker was trapped a kilometre underground for 16 hours after a small tremor triggered a 500 tonne rockfall.
Another miner was killed at the mine in 2010 after his vehicle fell 18 metres down a stope.
The mine is part of BHP's wider Nickel West operation, which includes Mt Keith, Kwinana, and the Kalgoorlie smelter.
