摘要: For minimizing surface subsidence, river sand is mostly used in abandoned coal mines filling. Due to increase the use of construction industries, mining industries are facing scarcity fill mine. After extraction from mines, large number leave without filling, which creates subsidence. Therefore, industry searching for an alternate filling material easily available quantity and minimal cost. The present work aims characterize utilize largely ashes mine applications study various issues related geo- environmental aspects same. From experimental results, it concluded that can replace conventional normally thereby cost project as well problems relating ash be reduced a significant extent. It was observed water holding capacity bottom considerably lower than pond fly ashes. XRD results show has more numbers quartz, mullite iron oxide peaks. this classified under Class ‘F’ according ASTM C618. However, general provide better filler ‘C’ ash, because calcium content low. Heavy metal concentrations were leached compared ash. Initially, when neutral mixed with acidic water, pH value increases after 24 hours gradually decreases attains confirming drinking standard.
