Large scale stability and Neutralisation capacity of Potential mine backfill material Formed by neutralisation of fly ash And acid mine drainage
Expanded Title:The study focus was on an assessment of the feasibility for large scale treatment of AMD from coal mines and recovery of water including: o Preliminary planning and consultation for large scale studies including, neutralisation, ash walling, ash lining, water recovery and mineralogical studies. o An evaluation of historical ash placement studies, to gain access and determine the mineralogical and other environmental impacts and changes associated with historical placements of ash previously used as fill materials o A determination of the overall suitability of solid residues for extending the life of coal mines and increasing the amount of extractable coal from each mine o The potential for control of surface AMD by employment of FA as ash walls within coal mine spoil heaps to establish performance as an in-situ barrier for passive treatment of AMD flows.
