Peabody Energy has commenced re-entry of Zone 1 of the North Goonyella mine in Moranbah in consultation with the Queensland Mine Inspectorate. This is part of a comprehensive, phased re-ventilation and safe re-entry plan for the mine, the company said.

The first zone of the mine represents approximately 25% of the area to be re-entered, and the area expected to be least affected by the incident. Upon re-entering Zone 1, Peabody will assess conditions underground and make any necessary repairs required prior to re-ventilating Zone 2.

The mine has been shut down since September after high gas levels were identified and shortly after, a fire broke out.
