Areas Mined for Coal in Illinois

Title: Areas Mined for Coal in Illinois - Part 1

Abstract:

Outlines of areas mined for coal in Illinois as of 1996. 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.

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.

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, 7.5-Minute Quadrangle 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 Q - Room and pillar panel; some pillars pulled R - Room and pillar; specific type unknown 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. MINE2 - Concatenation of M-INDEX2 and PIT2 items. MINE3 - Concatenation of M-INDEX3 and PIT3 items.
