Coronado halts Australian coal mine on roof collapse

US-Australian coal producer Coronado has paused underground mining operations at its mostly coking-coal producing Curragh complex in Queensland because of a fatal roof collapse on 2 January.

Queensland regulator Resources Safety and Health Queensland (RSHQ) has issued several directives to the mine to mitigate potential further risk to workers, RSHQ's chief executive Rob Djukic told Argus on 5 January. RSHQ investigators are also currently on site, Djukic added.

Coronado's open-pit mines at Curragh are operating normally, the company told investors.

Coronado has faced safety challenges before. The company suspended operations at its Lower War Eagle coal mine in West Virginia because of a fatal incident on 18 December 2025. But it has since restarted the mine, a Coronado spokesperson told Argus today.

West Virginia's Office of Miners' Health, Safety, and Training is conducting a full investigation into the incident, the state's governor Patrick Morrisey said.

Coronado's recent safety issues come alongside existing financial challenges. Australian state-owned electricity generator Stanwell finalised a long-term support package for the coal producer on 27 November 2025. The deal includes a mix of prepayment arrangements, loan facilities, and flexibility around existing coal supply contracts, Coronado said on 28 October 2025.

Stanwell previously agreed to support Coronado's Curragh complex through a $150mn coal prepayment deal on 10 June 2025.

But Coronado's financial challenges did not substantially impact production at Curragh in 2025. The company commissioned a continuous mining unit at the complex's underground mine in late-June 2025 and ramped up production at the site in July-September. It produced 3.1mn t of coal at Curragh over the quarter, up by 35pc on the year.
