Jan 30, 2017 Soil water systems have been severely degraded in coal‐mined and subsiding land, where a shallow groundwater table is also present. The present paper discussed the effects of fly ash (FA) and coal gangue (CG) as filling materials on the hydraulic properties and water content distribution in a profile for the purpose of rehabilitating subsided lands. The saturated water content, water.

Mar 27, 2021 Fly ash is the ash from burning coal that floats on the surface, while bottom ash is the ash that falls to the ground. Carbon, nitrogen, and silica are only a few of the FABA components. These components can then be used as a raw material for a variety of industrial goods, such as asphalt, pavement blocks, and road foundations.
