- and others
The objective of this study is to demonstrate the technical feasibility of placing fixated scrubber sludge (FSS) into abandoned underground coal mines to control subsidence and to reduce acid mine drainage. Effectiveness of the technology will be determined by the total reduction of the mine void, the strength of the placed FSS, and the overall effects on the hydrogeologic environment. A pilot scale test project was developed at the Petersburg Generating Station owned and operated by Indianapolis Power & Light (IPL). The pilot program encompassed approximately five acres underlain by abandoned and depleted coal mines, and involved the placement of approximately 16,000 cubic yards of FSS. The program entailed two separate tasks. Task one, performed by Conversion System, Inc. (CSI), involved a laboratory investigation, equipment testing and evaluation, design and assembly of a pilot plant, and the large scale field demonstration of fluid placement of FSS. Task two, performed by GAI Consultants, Inc. (GAI), evaluated both the impact on the hydrogeologic environment and the effectiveness of the surface subsidence control using fluid placement of FSS.
