Two more miners have died in accidents at Harmony Gold's Kusasalethu mine in North West and at its Joel mine in the Free
State.
Harmony's James Duncan says the accident at Kusasalethu occurred when a backfill paddock and bag failed, which resulted in an employee being buried under backfill material.
At the Joel mine, an employee died in a blasting accident.
Both incidents happened on Thursday afternoon, just hours after the bodies of eight missing miners were found following a fire at Harmony's Doornkop gold mine, west of Johannesburg.
Harmony chief executive Graham Briggs said the deaths were unacceptable.
He said shift general mangers had been tasked with re-enforcing safety messages and procedures, particularly in respect of critical safety areas.
