Book excerpt: Excerpt from Characteristics and Potential Uses of Waste From the Historic Longwall Coal Mining District in North-Central Illinois The first large-scale industrial coal mining operation in Illinois begun in the mid 7800s) produced more than 700 piles of waste - some almost 200 feet high, and many unstable. Most of these piles consist of shale, clay, and other debris resulting from min ing Operations; some consist of coal and clay separated from the coal during coal washing operations. Problems associated with the piles include slumping, erosion of gob materials onto adjacent farmland and streams, and runoff. In this study, conducted for the Illinois Abandoned Lands Reclamation Council, gob materials from 76 rapra sen ta tive sites were systematically samp led and tested, and six sites were studied in detail. Waste materials were classified on the basis of source material, mineral composi tion, geochemical properties, and color. Analyses of materials indicated that mining gob could be used for fired clay products, ligh t weight aggregate, landfill liners and levees, roads, and some foundations and fill, although considerable treatment might be required in some cases. Some coal could be recovered from preparation slurry deposits from discharge ponds at coal washing plants}, but coal cleaning would be required. Us. Epa Extraction procedures performed on mine waste materials and leacha tes did not indicate toxic or corrosive hazards; ho we ver, the potential for forma tion of acid leachates should be a consideration in the use of waste materials or rec/a mation of a site. Geotechnical engineering studies showed that slopes of the piles would generally be stable if slope angles were reshaped to about 20 to 30 degrees. Current reclamation technology cannot prevent all the problems associated with the piles, but reclamation of the mine sites can temporarily control the problems and in some cases provide parks or landfills for local residents.
