Pair were trapped underground for nine days and pitched a tent to keep themselves warm
Two South Korean miners who were trapped underground for nine days survived on coffee powder, authorities have said, after the pair were brought to safety.
The men walked free from a collapsed zinc mine in the north-eastern county of Bonghwa late on Friday. They had been trapped in a vertical shaft about 190 metres (620ft) underground after the mine collapsed on 26 October.
