Coal Mines, Coal Geology, and Resource Data Online
The Coal Mines in Illinois Viewer illustrates a general depiction of underground mining in the state, and by utilizing Google Maps, will help determine the proximity of coal mines and underground industrial mines to your home or business.
These selected 1:24,000-scale, 7.5-minute quadrangle maps show active and abandoned mines and their known extent. They are presented online as PDF versions on a topographic map base which includes township, range, and section lines and surface features such as roads, towns, lakes, and rivers. The mines are color-coded by mining method and the relative precision and completeness of the source map used for the mine boundary are indicated. Accompanying each map is a directory that gives a brief history of mining on the quadrangle and lists for each mine the location of mine opening and tipples; the name, thickness, and depth of seams mined; production history; geologic problems reported; company names; mine names and numbers; type of mine; years operated; coal seam mined; and mine location. Links to these same files are also now available via the county coal mine maps and directories pages and maps.
The series contains coal resource maps, coal mine maps and directories, and coal logs. This index is designed as a starting point for gathering information on coal and mines within an Illinois county. After choosing a county, you will be taken to the county webpage where links to the maps and coal logs are displayed. Coal resource maps on this page include structural elevation, depth, thickness, sulfur, and chlorine maps of the Colchester, Danville, Davis, Dekoven, Herrin, Jamestown, Seelyville, and Springfield Coals. The coal mine maps are maps compiled by the ISGS of known mines, both underground and surface. The coal mine maps and accompanying directories, which provide basic information about the mines, represent the most comprehensive compilation of available data. Please note, however, that the accuracy and completeness of the mine maps and directories vary depending on the availability and quality of source material. The coal logs are non-confidential coal log descriptions from the Coal Section's stratigraphic database located in the county. These are part of the basis for the coal resource maps.
Statewide coal maps on this page include structural elevation, depth, thickness, sulfur, and chlorine of major, potentially minable coal seams in Illinois. These include the Colchester, Danville, Davis, Dekoven, Herrin, Jamestown, Seelyville, and Springfield Coals. The maps presented here are page-sized (8.5 x 11 inches) maps available as PDF files. Herrin Coal structural elevation maps at a scale of 1:500,000 also available.
These statewide trace element maps, which also include ash, total sulfur, and pyritic sulfur content to organic sulfur content ratio, are PDF versions and show trace element concentrations in the Herrin and Springfield Coals.
Downloadable GIS Data
Digital coal resource shapefiles and raw database files available from the ISGS Coal Section. The listed shapefiles are the same ones that were used to construct the County Coal Map Series maps and Mined Out Area maps.

The Proximity of Underground Mines to Urban and Developed Lands in Illinois
Circular 575, 2009, study provides maps and statistics per county on the proximity of both coal and non-coal underground-mined
areas to urban development, and is an update of Treworgy and Hindman's 1991 study. The current report reflects newly available data coupled with a revised assessment
methodology which incorporates a mine-depth, rules based approach within the spatial calculations, and provides the most detailed view to date of the exposure of housing units
and developed land areas to the potential of mine subsidence.
