Abstract: Results from both laboratory and in-situ cone penetration tests (CPTs) on predominantly sandy silt platinum tailings from an operational mine in South Africa are reported. The CPTs were conducted with four different cone ...

Abstract: Over the past decade there has been increasing use of “paste” for backfilling of mined-out voids (“stopes”) in underground mines. Paste backfill is generated from full stream tailings and is almost always placed underground ...

Abstract: The evolution of the soil-water retention curve (SWRC) for cemented paste backfill (CPB) undergoing cement hydration is evaluated in this paper. A pressure plate apparatus and insertion tensiometers in a continuous drying ...

Abstract: In current underground mining practice, it is common to use tailings, without added cement, to fill mined-out voids (“stopes”). If fine-grained tailings are used, the high placement rates and low permeability can often ...

Abstract: In this paper, the discrete element method (DEM) is coupled with the Lattice Boltzmann method (LBM) to model the cone penetration test (CPT) of a saturated granular media. The coupled numerical model was calibrated using ...

Abstract: Electrokinetic experiments were undertaken to transport permanganate (

Abstract: An apparatus was designed, manufactured, and implemented to isolate pH during electrokinetic in situ chemical oxidation (EK-ISCO).
