Wage talks in the coal sector continued on Thursday as unions and employers looked to avoid strike action.
According to a report on Fin24, progress was made on Wednesday and the quick resolution to strike action in the gold sector has boosted hopes of similar action being avoided.
Unions have been asking for up to 60% in wage raises, but National Union of Mineworkers (NUM) general secretary Frans Baleni told Reuters that the union has "modified" its demands.
Trade union Solidarity, meanwhile, told the news agency that negotiations were at "a sensitive stage".
South Africa has been hit by large-scale strikes in recent weeks, and while the majority of unions have signed a new wage deal in the gold sector, one of the unions - the Association of Mineworkers and Construction Union (Amcu) - has yet to sign.
A strike in the coal sector could have a damaging effect on the country’s electricity supply and is the last thing needed in SA.
