| dc.description.abstract | This research aims to conduct a comparative analysis of slope stability
using two prominent geotechnical software programs, GeoStudio and
Rocscience, within the context of the Cipta Kridatama mining project
located in Jambi, Indonesia. The primary focus of this study is to evaluate
the safety factor of the slope, which is critical for ensuring the stability
and safety of mining operations.
The analysis employs the Fellenius (Ordinary) method, a widely
recognized approach for assessing slope stability. Key geotechnical
parameters are considered in this study, including soil cohesion (c),
internal friction angle (φ), unit weight of soil (γ), slope height (H), and
slope angle (α). Additionally, the groundwater level is assumed to be at
the slope surface, which is a crucial factor influencing the stability of the
slope. The slope object under review is a single cross-section of a slope
located at the PT Cipta Kridatama mining project, Jambi site. Analysis
results indicate that both software programs show high consistency (very
small or comparable differences) for each inter-ramp: inter-ramp 1 with
a difference of 0.006, inter-ramp 2 with a difference of 0.011, and inter
ramp 3 with a difference of 0.018. However, the most significant
difference is observed in the overall slope analysis, where Slope/W
yielded an SF of 1.477, while SLIDE produced an SF of 1.307, resulting
in a difference of 0.170. The selection of appropriate software in mining
projects and a thorough understanding of the analytical differences
between the two software programs are crucial for informed decision
making in slope design and risk mitigation, ensuring more responsible
open-pit mining operations, particularly at the PT Cipta Kridatama,
Jambi site. | en_US |
