This information was extracted from detailed coal mine data stored in the ISGS Coal Section library database. Lines delineate the approximate outer boundary of individual mines (if known) or general mined areas. Interior mine boundaries such as pillars or small blocks of unmined coal are commonly not depicted. Outlines have been compiled from a variety of sources. Outlines of areas mined before 1987 are commonly from source maps at scales of 1:62,500 or smaller. Outlines of areas mined since 1987 are commonly digitized at scales ranging from 1:4800 to 1:12,000. Mines whose extent is not known or which only mined a few acres are not included in this coverage. Selected areas where there are several overlapping mines are depicted in the companion coverage COALMINES_PY2. Use both of these coverages together for more complete representation of areas mined for coal. Attributes indicate mine identification number, mine type, mining method, and status. Additional information is available from the Coal Section of the Illinois State Geological Survey. Purpose: This coverage was compiled and updated between July 7 and December 31, 1996 in order to provide a current, state-wide coverage showing surface/underground coal mines for use with the ISGS Coal Industry Map (1996). Due to the wide range of source map scales, this data is suitable for regional applications only at the 1:100,000 scale or smaller. Supplemental_Information: Coverages COALMINES_PY and COALMINES_PY2 replace the Coal Mine Areas coverage that was distributed on the Illinois DNR CD-ROM of Digital Datasets in Illinois (1996). Revisions: This coverage is version 2, revision 0 (2.0). The previous revision (1.0) was included on the 1996 Illinois DNR GIS data CD-ROM release under the name CLMINEPY and is in the ISGS Coal Section GIS database under the name COALMINES_PY. > Changes for this revision: > (1) the data are updated to January 1, 1996, > (2) the items SEAM, MINETYPE, STARTYEAR, and FINALYEAR > have been dropped, and > (3) the valid values for the ACTIVE item were changed > to numerical format. Time_Period_of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: 1996 Currentness_Reference: The data library from which this coverage was extracted was updated with available information in 1996. The currentness of the update source documents is largely dependent on the mining companies that provide the requisite documentation.

Online_Linkage: Data Set Documentation Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Attributes in this coverage are accurate with respect to the source data library. Contact the ISGS Coal Section for information regarding the accuracy of the source data library. Logical_Consistency_Report: 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. Completeness_Report: 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. Interior mine boundaries such as pillars or small blocks of unmined coal are commonly not depicted. Mines whose extent is not known or which only mined a few acres are not included in this coverage. Areas where there are several overlapping mines are depicted in the companion coverage COALMINES_PY2. Use both of these coverages together for more complete representation of areas mined for coal. Not all the attribute data available for these coal mine locations are included in this coverage. For more detailed information contact the Coal Section of the Illinois State Geological Survey. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal positional accuracy is verified by visual comparison of source and hard copy plots. The source materials used are commonly paper copies (ozalid or hand traces) or microfilm prints of original mine maps supplied by mining companies or other parties. 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.

See Entity and Attribute Descriptions. Process_Step: Process_Description: These data are stored in county by county tiles in the ISGS Coal Section GIS database. To prepare this statewide map, coal mine outlines from all county tiles containing this theme were joined. Due to differing .pat item structures in the various county tiles of the coal mine library, a multi-step MAPJOIN operation was performed as follows: The following coal library coverages were MAPJOINed to create an interim coverage called C2: > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy > *path_name_suppressed*/minepy Process_Date: 1996 Process_Step: Process_Description: Coverage C2 was edited to check for internal consistency and to add polygon labels, and was saved as interim coverage C3.

These two items were dropped from C2A to give the two interim coverages identical item structures. Process_Date: 1996 Process_Step: Process_Description: The two coverages C3 and C2A were MAPJOINed to create new coverage ALLMNPY, which was subsequently renamed COALMINES_PY to conform with the name of the previous version.

Polygon attributes requiring further explanation are: > M-INDEX(n) - Unique ISGS identification number assigned > to each mine. A polygon can represent up to three mines because > of overlapping mines in different seams or surface mining through > shallow underground mines, or due to changing mine ownership and/or > permit status over time. > > PIT(n) - Pit number. This is used to distinguish between > different pits mined by a single surface mine or different seams > mined by an underground mine. PITn is associated with M-INDEXn. > > TYPE(n) - Polygon code associated with M-INDEXn. > A - Unmined area between mines > B - Indefinite mine boundary (surface mine) > H - Auger mine > K - Unmined area within a mine > L - Underground mine > M - Surface mine > N - Indefinite mine boundary (underground mine) > S - Abandoned surface mine or tipple > W - Abandoned slope > (no value) - other unmined areas > > METHOD(n) - Method of mining for M-INDEXn.
