Anotace: This study determines the mechanical properties, such as cohesion

and internal friction angle of the soil-rock mixture waste dump slope
at different consolidation pressures of 400 KPa, 800 KPa, and 1600
KPa and analysed the deformation of the slope models. The stability
of the slope was analysed by the discrete element method (DEM)
PFC2D and the Limit equilibrium method GEO 5. The results show
that the hazardous area is not only concentrated on the surface of the
waste dump's slope but also in the consolidation pressure of the soilrock mixture slope, which has the weakest consolidation strength,
making it prone to sliding.
