Acid mine, drainage (AMD) is a hazardous by-product of coal mining, which may intensify the creep deformation of cemented gangue backfill (CGB) in solid backfill mining. In this study, the long-term stability and creep property of CGB soaked in AMD were quantitatively measured by experimental and theoretical analysis. The uniaxial compressive strength, elastic modulus, and mass of CGB soaked in ...

The production of acid, including sulfuric acid, causes metals to leach from waste rock into water and has contaminated nearby Joe Creek with cadmium, copper, lead, arsenic and zinc at levels that are toxic to aquatic life. Joe Creek is unable to contain any self-sustaining populations of fish due to the mining waste.
