At least 37 miners are trapped underground following an powerful blast that destroyed two shafts Sunday at a coal mine in eastern Ukraine. The miners were making safety repairs at the Karl Marx mine in Donetsk. The blast occurred around some 1,000 meters (3,280 feet) underground. Four workers above ground were injured, including three women who were taken to hospital with severe burns. Rescue workers have begun trying to get to the trapped miners.
Ukraine has some of the world’s most dangerous mines due to outdated equipment and poor safety standards. Since the 1991 collapse of the Soviet Union, more than 4,800 miners have been killed in Ukraine. Officials say that for every one million tonnes of coal brought to the surface in Ukraine, three miners lose their lives.
