Pike River Coal Company has resumed control of mine stabilisation operations at the Pike River mine in New Zealand.
The firm will carry out a mine stabilisation plan by appointing a panel of experts, including those who were previously advising police, to maintain continuity in risk assessment advice.
The plan will provide a sustainable inert atmosphere within the mine, which is also free from any underground heat sources.
Receiver of the company John Fisk said stabilisation is a necessary first step to allow the investigation of options for the mine.
"However, there can be no assurance that the stabilisation plan will be successful or, even if it is, whether other options such as an eventual re-entry to all or part of the mine will be feasible," Fisk said.
