Abstract

Nowadays the amount of fly ash disposed as industrial wastes is increasing with increasing coal demands all over the world. Although fly ash is generally disposed by landfill, the demand of effective utilization of it is increasing because of the limitation of the disposal site. Moreover, there are few studies to use it as topsoil substitutes in coal mine. In this paper, the applicability of fly ash as topsoil substitutes at mined land in Indonesian open cut coal mine is discussed by means of physical and chemical analyses. Considering the obtained results, it was suggested that the utilization of fly ash as topsoil substitutes becomes possible by mixing topsoil and fly ash based on the physical characteristics and the amount of boron eluted from fly ash.
