All 955 workers who were trapped underground a gold mine in South Africa following a power cut have been safely brought back to the surface. <br/><br/>The miners were stuck in the Beatrix gold mine, in the small town of Theunissen near the city of Welkom, for around 30 hours after a massive power outage. <br/><br/>The huge power cut caused by a storm prevented lifts from bringing workers on the night shift to the surface. But today morning electricity was finally restored to a lift, enabling the miners to be brought up in batches, who had been trapped since Wednesday evening. <br/><br/>Mine spokesman James Wellsted said everybody is out and there were "cases of dehydration and high blood pressure but nothing serious". South Africa is a leading gold producer, but safety in the industry is often questioned.
