Abstract:
Paper maps of Eggert (1979) and Weismiller and Mroczynski (1978) were digitized to provide a GIS layer showing the approximate locations of coal-slurry deposits (CSDs) and associated preparation plants. Additional information on the locations of preparation plants and associated deposits was obtained from various reports in the IGS publication series titled "Directory of Coal Mines and Producers in Indiana," as well as from various editions of the Keystone Coal Industry Manual (Coal Age, 1987, 1989, 1991, 1993, 1995, 2000, 2005).

Using the shapefile of approximate locations to identify areas of interest, about 160 historical aerial photographs taken in those areas between 1937 and 1981 were then obtained from the archives of the IGS and georeferenced. Other imagery that was utilized included Digital Ortho Quarter Quads (DOQQs) of the U.S. Geological Survey (1998) and imagery of the National Agricultural Imagery Program (2003) and the Indiana Orthophotography Project (2005).

CSDs were identified on the historical aerial photographs and other imagery, and their boundaries were digitized directly from the imagery using ESRI ArcMap to create this polygon shapefile (COAL_SLURRY_DEPOSITS_IN.SHP). The historical development of some CSDs was complex. Wherever possible, imagery taken on various dates ranging from 1937 to 2005 was used to identify and map different stages in a CSDs development.

CSDs were emplaced in a variety of different settings. At underground mines, disposal cells were specially constructed, but at many surface mines, preexisting features such as final-cut pits and spoil deposits were utilized for slurry disposal. Disposal cells sometimes consisted of impoundments ("slurry ponds") that were bounded by berms constructed of gob (coarse-grained refuse from coal preparation) or spoil (disturbed and displaced overburden from surface mining). Boundaries of various features (e.g., berms, final-cut pits, spoil deposits) that were visible at the times when the photographs were taken were then digitized directly from historical aerial photographs or other imagery.

The identification of CSDs on imagery involved the evaluation of several factors. CSDs are typically situated close to preparation plants, although in some locations, slurry is pumped or flows for considerable distances through pipes or ditches before entering a disposal cell. Other factors indicating the existence of a CSD include the presence of berms, a generally dark gray or black appearance (except where the deposit is highly oxidized or where salts have formed on the surface), the existence of braided or meandering stream channels (indicating a flay-lying deposit), and an absence of shadows indicating that the deposit is elevated.

Older, unreclaimed CSDs may exhibit erosional features that typically have relatively low relief, in contrast to coarse-grained gob deposits, which were created by dumping refuse in a large pile. Unreclaimed gob deposits are also typically dark gray to black in color, but they may also exhibit steep-sided, eroded edges that cast long shadows. Gob deposits may also show evidence of straight travelways on their upper surfaces where dump trucks traversed the deposit. Although both CSDs and gob deposits are typically dark gray to black, the more elevated (and drier) portions of CSDs are often light-colored to white because of more pronounced weathering or the formation of salts on the surface.

Historical aerial photographs are typically black-and-white and may be of poor resolution, and CSDs are sometimes difficult to differentiate from gob deposits or other disturbed or barren areas associated with active mining, so that the recognition of CSDs invariably requires subjective interpretations by the investigator.

After the CSDs were identified and mapped, estimates were made of their thicknesses, and volumes were then calculated.

Purpose:
This GIS layer was created to show coal-slurry deposits (CSDs) that have been emplaced in Indiana since the 1930s in association with coal-preparation activities. CSDs contain significant quantities of coal that might be recoverable at some future date. The layer was used to calculate the volumes of slurry that are present at various sites.
Supplemental_Information:
This GIS layer was produced in association with other layers showing locations of coal-preparation plants in Indiana (COAL_PREPARATION_PLANTS_IN.SHP), locations of points where coal slurry was introduced (through pipelines or ditches) into disposal cells (COAL_SLURRY_DISCHARGE_IN.SHP), and locations of samples of coal slurry that were collected and analyzed by the Indiana Geological Survey (COAL_SLURRY_SAMPLES_IGS_IN.SHP).

Attribute_Accuracy_Report:
Historical aerial photographs are typically black-and-white and may be of poor resolution, and coal-slurry deposits (CSDs) are sometimes difficult to differentiate from gob deposits or other disturbed or barren areas associated with active mining, so that the recognition of CSDs invariably requires subjective interpretations by the investigator.

In order to provide volumetric estimates of the CSDs that were mapped, it was necessary to make assumptions regarding the thicknesses of the deposits. The following simplifying assumptions were made: (1) The thickness of a CSD emplaced in a final-cut pit ("FCP") was assumed to be equal to the depth of the coalbed that was mined. Also, the cross-sectional area of such a CSD was assumed to be rectangular. NOTE: This assumption does not take into account any slurry that was emplaced by overflow above the tops of final-cut pits. Also, for the purposes of this preliminary evaluation, inclined haul roads and haul roads that transected spoil ridges are also included in the category of "final-cut pit" at some mine sites. (2) The thickness of a CSD emplaced behind a berm ("GND") is assumed to be equal to the height of the berm. It is assumed that the CSD was emplaced on undisturbed ground (rather than an excavated pit). The cross-sectional area of such a CSD is assumed to be rectangular. (3) A CSD emplaced within a deposit of ungraded spoil ("SPL") is assumed to completely fill the troughs between parallel ridges. Spoil ridges are assumed to have an angle of draw of 30 degrees on both sides, so that the troughs between them are assumed to have cross-sectional areas that are isosceles triangles. Consequently, the maximum thickness of a CSD within any given trough is assumed to be approximately equal to one-fourth of the average spacing between ridges, and the average thickness is assumed to be approximately equal to one-eighth of the average spacing. NOTE: This assumption does not take into account any slurry that was emplaced above the tops of spoil ridges.

For a few features, site-specific drilling data exists regarding the thicknesses of individual CSDs. For most features, however, thicknesses of deposits were estimated using various preexisting datasets, as follows: (1) Final-Cut Pits ("FCP"). Depths to coalbeds in the vicinity of CSDs emplaced in final-cut pits were obtained from two sources: (a) Information on surface mines contained in the Coal Mine Information System (CMIS). (b) Drilling-log data that are tabulated in the National Coal Resource Data System (NCRDS). In general, the approximate elevation of the coalbed was determined from the drill hole that is geographically closest to the CSD feature. The depth of the coalbed at the feature was then calculated by subtracting the coalbed's approximate elevation from the elevation of ground at or near the feature. Where data are available from both the CMIS and the NCRDS, preference was given to the NCRDS data. For many features, a range of ground elevations exists, so that values for a "minimum" and "maximum" thickness were determined. (2) Undisturbed Ground ("GND"). The heights of berms associated with CSDs emplaced on undisturbed ground were estimated from topographic contour data contained in digital line graphs (DLGs) derived from 1:24,000-scale quadrangle maps of the U.S. Geological Survey. (3) Ungraded Spoil ("SPL"). The average spacing of spoil ridges associated with CSDs emplaced in troughs between such ridges was determined by measurements made directly from georeferenced historical aerial photographs and other imagery. Wherever possible, the measurements were made on the spoil ridges where slurry was later emplaced; where slurry was already present in all available imagery, measurements were made on nearby spoil deposits that were presumably associated with the same coalbed. (NOTE: Typically, georeferenced historical aerial photos have not been orthorectified.) As described above, the average thickness of the deposit was then assumed to be equal to one-eighth of the average spacing between ridges.

Of the deposits that are categorized as FCP, GND, and SPL, there are several situations for which thickness estimates are not possible in the absence of site-specific field data. These include: (1) Graded spoil deposits. (2) Active areas where slurry emplacement (or removal) has recently been occurring, as indicated by changes that are evident by comparison of aerial photography taken in 2003 and 2005. (3) Excavated pits, other than final-cut pits and impoundments on undisturbed ground.

Indicates that the coal-preparation plant associated with the CSD was active before 1978; activity may also have continued after 1978. The Surface Mining Control and Reclamation Act (SMCRA) was enacted in 1977. Before that date, standards of mining reclamation were primarily dependent on state (rather than federal) statutes. After that date, standards of mining reclamation were primarily dependent on federal (rather than state) statutes.
