The "One miner dead, one day off" campaign by NUM is beginning to bite.
Miners at Nkomati Platinum downed tools last week to mourn a colleague who died at work.
The trade union resolved last year that it would take a day off "to mourn a colleague" whenever there was a fatal mining accident.
"We are observing our culture, which says we should mourn if there is a death," NUM spokesman Lesiba Seshoka said.
"The decision was taken by our members and we conveyed it to the mine owners," Seshoka said. "They objected but members went ahead anyway."
NUM reported 231 mine deaths last year. This year 130 miners have so far lost their lives.
Seshoko said most deaths occurred at Goldfields' mines, which NUM claims have not improved their safety standards. African Rainbow Minerals (ARM) also had high casualty figures, NUM said.
ARM chief executive Steve Mashalane told Sowetan: "We observe stringent safety measures and steps are taken against those who break them."
