JOHANNESBURG - Another two workers have died at mines belonging to Harmony Gold, just days after eight workers were killed following an underground fire at the company's Doornkop Mine, west of Johannesburg.

Harmony Gold says a worker was killed in a blasting accident at its Joel Mine in the Free State on Thursday night and while another death was reported at its Kusasalethu Mine near Carletonville.

All blasting at the company has since been halted and its CEO Graham Briggs says all workers on duty today will be safety shifts.

Earlier today, questions were asked about mineworkers' compliance with safety regulations and equipment used in underground emergencies following the deaths at the Doornkop mine.

The bodies of the eight men were found on Thursday after a fire broke out underground on Tuesday.

The blaze followed a seismic event, which triggered a rock fall.

Initially, reports stated 17 miners were unaccounted for after the fire broke out, but nine were rescued and one miner is still missing.
