Mine workers await their shift outside the Doornkop Gold Mine, about 30 km (19 miles) west of Johannesburg September 3, 2013. South African President Jacob Zuma on Tuesday appealed to unions and companies in the gold industry to avoid an imminent strike that could seriously damage Africa's largest economy, force mine closures and cost thousands of jobs. Gold miners were set to strike for higher pay from Tuesday, after talks between unions and companies broke down last week.
