About 900 million tons of coal has been produced in Indiana by underground mining. The total area undermined is more than 100,000 acres, or about 150 square miles, mostly in Vermillion, Vigo, Sullivan and Knox Counties. Mines have ranged from one-person operations to mines employing hundreds of workers. The states largest mine - more than 9 square miles - was Kings Station Mine in Gibson County south of Princeton. It closed in 1972.
