The company said it has launched processes "which may result in the closure of the mine and placement thereof on care and maintenance and possible retrenchments."
The announcement marks an uneasy start to the year for South Africa's key mining sector, which in 2012 went through a devastating and costly bout of labour unrest.
Last year's nationwide strikes left more than 50 people dead, starting with violence in August at London-listed Lonmin's Marikana platinum mine, before spreading to other mines and sectors. The strikes affected over 140,000 workers and cost more than US$1.2bn.
Harmony Gold chief executive Graham Briggs said in a conference call that currently "secure and safe production is just not possible" at the Kusasalethu mine at Carletonville, south-west of Johannesburg.
The mine, which employs some 6,000 workers, has not re-opened since it shut before the Christmas holiday break.
"There is extremely high risk that something will go wrong at Kusasalethu in its current state," said Briggs. "We are drawing a line in the sand."
He said live ammunition had been fired at mine security guards during the December unrest, while mine managers had received death threats.
"Management is of the view that the status quo concerning production and labour strife will remain, as it has exhausted all possible avenues to achieve normal production and cannot find a solution to the current state of lawlessness prevailing at the mine," said the company in a statement.
"This is a difficult situation, it's quite sad for us to do this," Briggs added.
In the latest troubles to hit the mine, protesting gold miners clashed with police and private security guards last month. Ten workers were hurt by rubber bullets or tear gas as 1,700 others staged a 38-hour underground sit-in.
In November, two workers were killed and one wounded in a turf battle between members of rival unions at the same shaft.
Harmony has 10 underground and several surface operations in South Africa. It bought Kusasalethu in 2001.
