Introduction
Anglo American is approaching a critical milestone in the recovery of its Grosvenor underground coal mine, nearly one year after a devastating methane gas explosion shut operations. The mine, located in Queensland’s Bowen Basin, is undergoing final re-entry preparations, with laser imaging, drones, and even robotic technology trialled to ensure worker safety.
While the reopening promises hope for returning miners, questions remain about long-term safety practices and job security following multiple explosive incidents at the site.
Details of the Incident
The Grosvenor Mine was evacuated in June 2024 after a methane ignition incident—eerily similar to a 2020 explosion that injured five workers. This latest event led to a full operational halt and intense scrutiny from regulators and unions.
Grosvenor Mine technical assurance manager Wesley Noble explained that teams are still removing material that had filled the underground shafts during the crisis. “We were able to utilise [laser] technology… to map the underground workings from the surface,” he said.
Advanced technology, including drones and thermal imaging tools, has been deployed for structural and environmental assessments. Anglo American is also reportedly evaluating the use of a robotic dog—nicknamed “Spot”—to reduce human exposure to hazardous environments.
Regulatory Actions and Findings
Resources Health and Safety Queensland (RHSQ) confirmed it is actively monitoring re-entry efforts at Grosvenor and has permitted preliminary construction activities underground. A “staged approach” has been approved for Anglo American’s other affected site, Moranbah North, which also experienced a methane incident.
The union representing mining and energy workers continues to enforce a directive that prevents its members from entering the mine. Industry health and safety representative Jason Hill stated the ban would only be lifted once there’s an “acceptable level of risk”.
Broader Implications
The repeated gas-related incidents at Grosvenor have reignited concerns about ventilation, methane detection systems, and the reliance on human re-entry too soon after high-risk events. Jason Hill of the Mining and Energy Union noted the emotional and financial strain on the workforce:
“A lot of the miners that come from Grosvenor… what I’m hearing, and what I’ve been told, want to go back,” he said. “Getting this step forward… will provide some security.”
Robotics expert Professor Mohsen Yahyaei from the University of Queensland supports the push for AI-powered safety solutions. “You remove the human being from those hazardous environments, and therefore you improve the safety aspect,” he explained.
Company Response
Grosvenor general manager Shane McDowall said the company’s focus remains on “safely re-ventilating the underground environment” before full re-entry. “Our teams will return underground, carry out visual inspections, and continue readiness activities,” he added.
A spokesperson for Anglo American also highlighted the company’s collaboration with RHSQ and union safety officers to ensure “compliance at every stage of the re-entry plan”.
Facility Details
Grosvenor Mine is the largest underground coal mine in Queensland’s Bowen Basin, previously employing around 850 permanent and contract workers. The mine forms part of a $5.7 billion acquisition deal by Peabody Energy, with resumption of mining at Grosvenor tied to the final purchase price.
To assess re-entry, teams have used:
- Laser imaging down boreholes
- Drones for thermal and gas mapping
- Artificial intelligence and robotic dogs for surveillance
Conclusion
As Anglo American prepares to restart operations at Grosvenor Mine, stakeholders remain cautious. With worker safety, technological innovation, and corporate accountability all in the spotlight, the reopening will serve as a pivotal test of Queensland’s mining safety regime and industry resilience.
