1st August 2018

The NSW Resources Regulator has lifted a prohibition notice allowing limited longwall activities, under controlled conditions, to recommence at Austar Mine.

On 18 May 2018 the Regulator issued a notice prohibiting all underground longwall production, following a significant coal burst event which occurred on 17 May 2018.

The notice was lifted on 30 July 2018 after the implementation of additional controls by the mine, including de-stress drilling and the training of staff in pressure bump identification and coal burst trigger action response plans.

A further prohibition notice remains in place which prohibits longwall extraction from the 293m chainage.

The mine will undertake controlled cutting under strict conditions up to this point in order to test additional controls to mitigate a coal burst risk, and will maintain a 50-metre exclusion zone for workers.
