| dc.description.abstract | Slope stability is the primary factor in designing a stable slope. The strength of
the disposal slope relies on the characteristic of the dump materials. The rock
shear strength denotes the rock's ability to withstand the burden, both constant
and dynamic load. The weakest material used as a reference in designing the
disposal slope is siltstone in Pulaubalang formation (location-04). The safety
value in locations 04 and 02 tend to drop quickly as the inclination increase,
while the safety in locations 01 and 03 tend to fall slowly. This indicates that
rocks with a lower plasticity index tend to be stronger in steeper slope
conditions. The slope geometry was designed to be 10, 15, 20, and 25 m high
with a slope angle of 10o, 15o, 20o, 25o, 30o, 35o, 40o, 45o, 50o, 55o, and 60o. The
slope geometry is considered stable and safe. However, this study suggests that
the most effective slope design is the slope with 25 m high, an overall slope of
25.3o; a single slope of 35o; a berm width of 4.66 m, bench height of 5 m, with
a safety factor value of 4.30 (SF= 4.30). | en_US |
