JOHANNESBURG - Another mineworker has died at a Sibanye-Stillwater mine, less than a week after two people were killed at another shaft, the National Union of Mineworkers (NUM) said. 

The union said a worker was killed at the Driefontein&39;s No. 1 shaft on Monday while trying blast an ore pass box that was blocked by big rocks.

When the rock was crushed, a rush of mud overwhelmed the worker, who suffocated to death. 

A rockfall at the company&39;s Kloof mine killed two people on Wednesday

“We are very much concerned about the loss of lives happening at Sibanye-Stillwater," said Mbuyiseli Hibana, NUM Carletonville regional secretary.

“The company must be made to account on all of these incidents and those found responsible must be made to take the blame."

In another incident in January, more than 1,100 miners were trapped underground at the Beatrix gold mine in the Free State province, after a power outage at the mine caused by a severe storm in the area. No one was injured. 

Trade union Nehawu has demanded all Sibanye mines be shut down until they can be declared safe.
