Peabody says it has commenced re-entry of Zone 1 of the North Goonyella coal mine, in Queensland, Australia, in consultation with the regional mine inspectorate.

These activities are part of a comprehensive, phased re-ventilation and safe re-entry plan for the mine, which has been shut since early September when high gas levels were identified. Following this discovery, a fire broke out later that month.

Peabody Australia President, George J Schuller Jr, said: “Following the re-ventilation of Zone 1 of the mine, our team is ready to return underground and move us yet one step closer to resuming normal operations. We appreciate the dedication and participation of our trained employees, as well as the Queensland Mine Rescue Service, as we continue to advance this process.”

The first zone of the mine represents around 25% of the area to be re-entered, and the area expected to be least affected by the incident.

The company said: “Upon re-entering Zone 1, Peabody will assess conditions underground and make any necessary repairs required prior to reventilating Zone 2.”
