"Application of fine desulfurised coal tailings as neutralising barriers in the prevention of acid rock drainage" -  A. Kotsiopoulos, S.T.L Harrison

  • Co-disposal of sulfur lean tailings with coal interburden is investigated in the prevention of acid rock drainage (ARD)
  • Fine tailings are applied to exclude the permeation of oxidants to acid generating waste rock surfaces
  • Benign barriers as either alternating layered covers or blends with the acid generating coal interburden are investigated
  • Tests are performed under continuous flow conditions to assess the neutralising efficiency over prolonged periods of time
