"Rescue workers scrambled to save 83 people trapped in Russia's largest underground coal mine after two explosions killed at least 12 people and injured dozens more, officials said. Among those still trapped early Monday were rescue workers who had entered the Siberian mine after the first blast."

"The Raspadskaya mine produces about 8 million tons (8.8 million short tons) of coal a year, according to the company's website."

Terrible way to go.
