These data were extracted from the ISGS Coal database. Because there is no legal filing requirement for non-coal mines in Illinois, these data show only approximately 20% of the non-coal mines in the state. Mine index numbers can be related to tabular mine information maintained by the ISGS Coal Section. These data are not actively maintained. A much more comprehensive non-coal mine point data set is in preparation. This data set was assembled as a subset of all underground mines in Illinois to identify areas that may be subject to mine subsidence. These data have a nominal scale of 1:24,000. none 199612 publication date complete none planned -91.47780541 -87.93918145 42.49916694 37.30415203 none geology mines underground none Illinois none Reproduction or redistribution of copyrighted digital data sets or products derived therefrom outside of licensee's organization or entity is expressly forbidden.

Contact the ISGS Coal Section for information regarding the accuracy of the source data library. Note: A polygon with CODE = 12 is also present with the database, but is probably mis-coded. Polygon and chain-node topology is present. The coverage was checked for complete chain-node topology (no dangling arcs, except where appropriate), polygon labels (one per polygon, except for universal polygon), boundary values appropriate for map projection and map units, and appropriate "fuzzy" tolerances. There are no known arc or polygon attribute values outside the appropriate value domains. This data set does not represent a complete collection of the location of mine shafts, slopes, and other openings. Lines delineate the approximate outer boundary of individual mines (if known) or general mined areas. It is estimated that less than 20% of the non-coal underground mines in Illinois are represented. Horizontal positional accuracy is verified by visual comparison of source and hard copy plots. The source materials used are commonly paper copies of original mine maps or USGS 7.5' quadrangles. ISGS staff have not verified the accuracy or validity of the original source material. Some original maps are not drawn on a cartographic base. Due to the physical and cartographic quality of the source materials used, horizontal positions may be in error by 500 feet or more. For applications requiring precise horizontal accuracy, the original source maps should be consulted. Coal Section, Illinois State Geological Survey 1996 Champaign, Illinois Illinois State Geological Survey varies digital files 1996 unknown none mine outlines and index numbers This data set was created from digital data maintained by the Coal section of the Illinois State Geological Survey. The data is separated into county-by county databases archived on-line in /coal4/library. If a non-coal polygon coverage existed within a county database, it was copied to a separate workspace. There were a total of 15 counties with non-coal polygon coverages. The 15 individual coverages were combined into a single coverage with the ARC/INFO APPEND command. 1996 Vector Point 77 String 192 GT-polygon composed of chains 78 Lambert Conformal Conic 33 0 0.000 45 0 0.000 -89 30 0.000 33 0 0.000 914400.00000 meters 0.00000 coordinate pair unknown unknown feet NAD27 CLARKE1866 6378206.4 meters 294.98 Attribute items are in typical ARC/INFO feature class format.
