Characterization of material at the base of spoil piles coal mines
- Compare variability of laboratory measured properties of category 2 soil material for a range of overburden pressure scenarios.
- Compare reduction in strength, slaking potential and spoil disintegration for category 2 material over time for a range of overburden pressure scenarios.
- Models to estimate materials properties such as slaking, PSD, permeability, consolidation and shear strength of category 2 spoil foundation material at given time and a given soil height.
- Create or provide guidance of appropriate material parameters for category 2 spoil material to be used in design at different time and spoil height scenarios.
