Effect of stacking parameters on stability of paste tailings accumulation body

Surface paste tailings disposal is a new tailings disposal technology,which has outstanding advantages in safety,environmental protection,operation and management.The stability of stacking body with different emission modes,stacking heights and slope angles is studied in this paper with limit equilibrium theory by software Geo-Slope.It is shown that the slope safety factor is negatively correlated with the stacking height and slope angle,and the slope angle has greater influence.
