Some characteristics of solidified coal ash are studied. With regard to seepage prevention, stability insurance and uneven settlement prevention, some engineering measures and design requirements are also studied. Some specific construction and maintenance requirements are discussed. Also, the tech economic and environmental benefits are analysed. It is proved that the heightening of ash dams with solidified coal ash is technically feasible, and economically rational, thus it can be popularized.
