The 2008 Ukrainian coal mine collapse occurred at the Karl Marx Coal Mine in the city of Yenakiieve, Donetsk Oblast (province) of eastern Ukraine on June 8, 2008. The mine collapse was said to have been caused by a gas pipe explosion. The explosion occurred at a depth of about 1,750 feet (533 m). 37 miners were trapped underground at the time of the collapse, located 3,301 feet (1,006 m) below the surface of the earth. Additionally, five surface workers suffered from burns and other injuries in a blast that they described as one of the most powerful in the industry.
