Abstract
Coal mine surface dumps and surface mine spoils generated by previously uncontrolled surface mining and dumping of preparation plant refuse have been responsible for environmental and aesthetic problems. One potential method of treatment developed by the Bureau of Mines employs powerplant fly ash as a soil-building amendment. Application of tonnage quantities of fly ash has resulted in successful revegetation of experimental sites with grasses and legumes. Where plant growth has been inhibited in some instances by high salt content of the fly ash-spoil mixtures, weathering appears to remedy the adverse conditions. Tree plantings on fly ash-treated areas are more effective when a heavy ground cover has been established first with grasses and legumes. This study, as well as studies by others, has indicated that there are basic chemical and physical benefits to be gained from utilizing fly ash on spoils, waste areas, and agricultural soils.
