Illinois State Geological Survey Mine Maps

Map Information

Coal has been mined in 73 counties in Illinois and more than 4,500 coal mines have operated since commercial mining began in 1810. The ISGS compiles maps of known surface and sub-surface coal mines.

The coal mine maps and accompanying directories, which provide basic information about the mines, represent the most comprehensive compilation of available data. However, please note, the accuracy and completeness of the mine maps and directories vary depending on the availability and quality of source material. Little or no information is available for many mines, especially the older ones, because mining activity was not regulated or documented until the late 1800's.

These maps of known mines may help the user identify areas that may be subject to mine subsidence. However, understanding that maps of some mines may be unavailable or incomplete, mine subsidence may occur in areas not documented as undermined.
