Coronado said in a statement that a return to work plan had been developed to ensure tyre work was resumed in a safe and controlled manner.
"A detailed investigation was launched by the inspectorate when Donald Rabbitt, an employee of Curragh mine contractor Thiess, was fatally injured during a tyre change activity in the main workshop on January 12 2020," it said.
"The company was supportive of the directive and all efforts to improve safety at its operations.
"Coronado continues to conduct its own investigation to understand the causes of the incident and continues to support the third-party reviews underway."
Production at Curragh resumed in a phased approach from January 17.
Coronado said following the resumption of tyre and wheel rim fitting activity, there were no ongoing restrictions on mine operations.
