What does this data set describe?

Title: Areas Mined for Coal in Illinois - Part 2
Abstract:
This is the companion coverage to COALMINES_PY, showing additional areas where there are several overlapping areas mined for coal, updated to 1996. Most mapped coal mines are depicted in the coverage COALMINES_PY. Use both of these coverages together for a more complete representation of areas mined for coal. 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. 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.

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).

  7. How does the data set describe geographic features?

    Entity_and_Attribute_Overview:
    Attribute items are in typical ARC/INFO feature class format. 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.  For a detailed
     description of these methods see: Bargh, M.H., C.G. Treworgy,
     G.K. Coats, 1993, Directory of Coal Mines in Illinois,

     Series, Springfield East Quadrangle, Sangamon County.
               B - Blind room and pillar
               C - Checkerboard room and pillar
               H - High extraction retreat
               L - Longwall
               M - Modified room and pillar
               N - Modified room and pillar; some pillars pulled
               O - Room and pillar basic (irregular panels)
               P - Room and pillar panel

               S - Room and pillar; some pillars pulled
    
     ACTIVE - Status of mine.  Due to the nature of coal mining,
     active/inactive status of a mine may change frequently.  These
     designations are current as of September 1, 1996.
               1 - Active mine
               0 - Inactive mine
    
     MINE  - Concatenation of M-INDEX  and PIT  items.

Why was the data set created?

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.

  2. How were the data generated, processed, and modified?

    Date: 1996 (process 1 of 6)
    Procedures Used: These data are stored in county by county tiles in the ISGS Coal Section GIS database. To prepare this coverage, 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 UNION operation was performed.

    The following coal library coverages are those that contain information for overlapping coal mines/seams used in this coverage.

     *path_name_suppressed*/mpoly200
     *path_name_suppressed*/mpoly220
     *path_name_suppressed*/mpoly999
     *path_name_suppressed*/mpoly200
     *path_name_suppressed*/mpoly220
     *path_name_suppressed*/mpoly999
     *path_name_suppressed*/mpoly220
     *path_name_suppressed*/mpoly250
     *path_name_suppressed*/mpoly200
     *path_name_suppressed*/mpoly220
     *path_name_suppressed*/mpoly999
     County is indicated by c*** and mine layer is indicated
     by mpoly***.
    

    Date: 1996 (process 2 of 6)
    In order to UNION these coverages, item names and definitions had to be altered to insure that no information was lost.
     To do this, the coverages were copied to the following:
     copy *path_name_suppressed*/mpoly200 mp059
     copy *path_name_suppressed*/mpoly220 mp259         2
     copy *path_name_suppressed*/mpoly999 mp959         3
     copy *path_name_suppressed*/mpoly200 mp0165        4
     copy *path_name_suppressed*/mpoly220 mp2165        5
     copy *path_name_suppressed*/mpoly999 mp9165        6
     copy *path_name_suppressed*/mpoly220 mp2183        7
     copy *path_name_suppressed*/mpoly250 mp5183        8
     copy *path_name_suppressed*/mpoly200 mp0199        9
     copy *path_name_suppressed*/mpoly220 mp2199       10
     copy *path_name_suppressed*/mpoly999 mp9199       11
    
    The number in the rightmost column above was used in the item redefinitions to create a unique set of items for each coverage. The polygon attribute items for the coverages are listed below. For each coverage, the asterisk was replaced with the corresponding number. For example, the asterisk would be replaced by the number 3 to uniquely identify the set of attribute items in coverage mp959.

    The coverage was copied to COALMINES_PY2. As a result of the UNION operation, each record had 132 items definitions in 33 groups of 4 (X1A, P1A, T1A, M1A ........ X11C, P11C, T11C, M11C). However, most of these fields were blank; no single record represented more than five unique mine index numbers. An AML was created to reduce the items to the minimum necessary, which was determined to be 5 groups of 4 items each. Prior to running the AML the items had to be renamed to use numbers for easier processing. Thus the items definition names became: X11, P11, T11, M11 ......... X113, P113, T113, M113 respectively.

    This is the AML that was used.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    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.

  2. How accurate are the geographic locations?

    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.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    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. The companion coverage COALMINES_PY shows considerably more mined areas than this coverage. This coverage and COALMINES_PY should be used 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.

  5. How consistent are the relationships among the observations, including topology?

    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.


How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
