This unpredictable West Virginia coal Mine Explosion is worst U.S. mining accident in over two decades.About 50 mourners are at West Virginia church a few miles from the site of a deadly mine explosion to remember the 25 victims and pray for four missing miners. May some people went missing after a huge underground explosion in that dark mine. Everyone is hoping for a miracle like the one in Sago where, 40 hours after an explosion, Randal McCloy Jr. was pulled out alive.
