Ans. Yes, fly ash is a good material to substitute sand for back filling of open cast mines. Coarser portions of fly ash that is bottom ash and coarse ash from pond ash are even better materials than sand for this purpose. Fine ash particles that take relatively longer time for settlement, can also be settled faster with application of appropriate technology.
