This GIS layer was produced in association with another layer showing locations of coal-slurry deposits (CSDs) in Indiana (COAL_SLURRY_DEPOSITS_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).
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).
Preparation plants were identified on the historical aerial photographs and other imagery, and their locations were digitized directly from the imagery using ESRI ArcMap to create a point shapefile showing exact locations (COAL_PREPARATION_PLANTS_IN.SHP).
Preparation plants are typically tall structures that may cast long shadows and are sometimes associated with silos, conveyor belts, or smoke stacks. Preparation plants--particularly older plants and plants associated with underground mines--are often situated on rail lines (with multiple tracks adjacent to the plants), while more recent plants associated with surface mines are often connected to various pits by broad haul roads that are distinctive on aerial photographs. However, the plants--particularly those associated with surface mines--were often dismantled or moved when mining activity shifted to other areas.
This GIS layer was produced as part of an investigation that was conducted in 2006-07 that was a cooperative project of the Indiana Geological Survey, R.E. Mourdock and Associates, LLC., and Purdue University, Calumet. Funding was provided by the Center for Coal Technology Research, Purdue University, West Lafayette.
