When the roof of a coal mine collapsed in the Georgian town of Tkibuli in July, killing four miners and injuring six, the small town was plunged into grief. Not for the first time. In fact, just three months previously in April in an accident at the same pit, six miners were killed and three injured. In all, 32 miners have died in accidents at the Mindeli mine in Tkibuli, 200 km west of the capital Tbilisi, over the past decade and most local men acknowledge that if they could find other work they would do. The reality is there is no other alternative. REUTERS/David Mdzinarishvili SEARCH "GEORGIA MINE" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES. TPX IMAGES OF THE DAY.
