The operators of the Grasberg mine in Indonesia's Papua region have restarted operations, after the government completed its preliminary investigation into the fatal tunnel collapse two weeks ago.
Inspectors from the Ministry of Energy and Mineral Resources have given the company Freeport McMoRan several recommendations regarding their operations.
The company says it is carrying out maintenance on its underground operations and hopes production will be sped up after being closed for two weeks.
The company is estimated to lose nearly two million US dollars for each day of closure.
The collapse happened in a training facility some distance from the mine operations, and killed 28 workers who were undergoing safety training.
