Effect of fly ash grout backfills on groundwater environment
In order to utilize the fly ash grout backfills in overburden strata to solve the serious problem of large pillars being left under villages and to ensure the safety of drinking water supply in mining area, groundwater quality was studied before and after the fly ash grout backfills was implemented.This paper analyzed the influence of fly ash grout backfill operations on water quality of drinking water at Nos.1 and 2 aquifers in the Quaternary strata, Permian sandstone aquifers, limestone aquifers,and mine water.Preliminary conclusions were presented.
