Some 3,200 miners were trapped deep underground in a South African gold mine on Wednesday and a union spokesman said they could be suffocating.The miners at the Elandsrand mine were caught about 2.2 km down after a power cable to a lift broke at around 9:00 a.m. British time on Wednesday, a spokeswoman for owners Harmony Gold, the world's fifth biggest gold producer, said.
A National Union of Mineworkers (NUM) spokesman said the miners were trapped in a cramped space where temperatures could reach 30 to 40 degrees Celsius (86-104 Fahrenheit).
"We are very worried because ... they might be suffocating," NUM spokesman Lesiba Seshoka said. "There is no contact at the moment. That is our greatest worry."
