The Mount Lyell Copper mine will remain closed until investigations in to the fatal accident last week have finished.
On Friday 53 year old Michael Welsh, a Barminco contractor at the site, was killed when a mudslide tore through the lower levels of the mine.
In December operations were suspended at the Queenstown mine following the double fatality, where the men, Craig Gleeson, 45, and Alistair Lucas, 25, were killed in a mine shaft accident.
Operations have now again been suspended as the probe into the incident is carried out, according to The Advocate.
"Investigations are still continuing into the tragedy, and the mine will remain closed until those are complete," Australian Workers Union Tasmanian secretary Ian Wakefield said.
"The workers are really taking it hard and it comes just weeks after the incident in December.”
This isn’t the first time the site has suffered a mud rush, when in 2009 Mt Lyell was forced to close for weeks due to the landslip incident.
Wakefiled added that operations at the mine will only restart following the safety review.
