South African miners locked up

johannesburg - Due to the collapse of a corridor, thirteen South African miners got stuck underground on Thursday. The cause was a slight earthquake. According to the management of the Masakhane gold mine, west of Johannesburg, rescue workers have been able to make contact with three of them.

'We are making every effort to locate the ten others and to bring everyone safely up', according to the statement from the operating company Sibanye-Stillwater.

South Africa has the deepest mines in the world and many mines are therefore considered dangerous by geologists. In February, severe weather put down the power supply of the Beatrix mine of the same company. Then more than a thousand workers were locked up for more than 24 hours. They could be saved.
