An urgent rescue operation is underway at the Curragh coal mine complex near Blackwater in Central Queensland following a devastating roof collapse that has left one worker trapped underground, possibly 1km deep, sparking mounting fears for his life as hours turn into days.

The incident unfolded around 3pm on Friday, January 2, at the Mammoth Underground mine within the Curragh complex, operated by Coronado Global Resources. Three workers were affected when a section of roof gave way in a development panel, trapping them in unstable conditions. Two were rescued safely — one with non-life-threatening injuries and airlifted to hospital — but the third remains unaccounted for, believed to be in a confined space amid risks of further falls.

“We are doing everything possible,” Acting Mines Minister Tony Perrett said in a statement. “Emergency crews, including the Queensland Mines Rescue Service, are on site, but safety is paramount. My thoughts are with all involved, their loved ones, and the entire mining community.”

Resources Safety and Health Queensland (RSHQ) confirmed the roof collapse and is leading a thorough investigation. “Loss of life in mining operations is unacceptable,” RSHQ said, noting the focus is on supporting recovery efforts while assessing structural damage.

Police were called to the scene shortly after the collapse, establishing a command post as Mines Rescue teams deployed drones, remote cameras, and specialist equipment to navigate the hazardous environment. Conditions are described as “extremely unstable,” with geotechnical experts monitoring for secondary collapses. By Saturday morning, the search had entered its second night, transitioning toward recovery as hope waned.

The missing worker, an experienced longwall operator in his 30s, is a family man known to colleagues as reliable and dedicated. “He’s one of the best — always looking out for his mates,” a co-worker told ABC News, voice cracking. Families have gathered at the gate, clutching photos amid vigils in Blackwater, a town where mining defines life.

Curragh, one of Australia’s largest coal producers supplying metallurgical and thermal coal, has a history of incidents, including a 2020 methane explosion injuring five. Coronado CEO Douglas Thompson expressed devastation: “We extend our deepest sympathies to the family, friends, and colleagues. We are cooperating fully with authorities.”

Premier David Crisafulli visited the site, pledging resources: “This is every family’s worst fear. We’ll leave no stone unturned.” The Mining and Energy Union demanded an independent probe, highlighting ongoing safety concerns in Queensland’s Bowen Basin.

As hours stretch on, attention fixes on the rescuers battling darkness and danger. What began as a routine shift has become a haunting reminder of mining’s perils — where an ordinary day underground turns to nightmare. For the trapped worker’s loved ones, every update brings dread and dwindling hope. Queensland holds its breath, praying for a miracle in the depths below.
