Description:
The technical and economic aspects of surface treatment of regraded acidic strip mine spoils with pulverized fuel fly ash as a method to produce a soil cover which will sustain grasses and legumes and also enhance abatement of mine drainage are discussed. Data on present stream water quality of Hillman State Park was obtained to establish a set of parameters which will be used for comparison with future water quality analysis in order to determine effects of construction and the application of fly ash to the water quality. Other criteria used in this evaluation include: pH of strip mine spoil material and fly ash; moisture retention characteristics of spoils and spoils treated with fly ash; and grain size distribution of spoils treated with fly ash. The feasibility study results indicate this demonstration project would be technically feasible and the reclamation would be effective to produce useable land and improve water quality.
