Abstract EN
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 AMD, with pH of 5.56 and soaking time of 30 to 360 days, were tested.
The change trend of compressive strength, elasticity modulus, and mass first increased, then decreased, and finally ended at 94.37%, 96.68%, and 98.00%, respectively.
The respective creep processes of CGB soaked in AMD and untreated CGB were similar, initial creep stage lasted only for a short time, and no creep deformation occurred in the steady creep stage.
Moreover, the long-term strength of CGB soaked in AMD was 98.6% of the untreated CGB.
The creep law of the CGB soaked in AMD was accurately fitted by using the Kelvin model.
The theoretical analysis revealed that the final creep deformation of the CGB column soaked in AMD was only 4.4 mm.
The results of this paper show the possibility of using CGB in AMD-accumulating goaf.
