ABSTRACT

PT. Kuansing Inti Makmur (PT. KIM) is a company engaged in the field
of coal mining, PT. KIM was established on January 2004, as a subsidiary of PT.
Golden Energy Mines Tbk, located at Sinarmasland Plaza Tower 2, 6
floor, Jl.
MH. Thamrin No. 51, Jakarta.
The best result of physical and mechanical properties attained from the
rock sampling in the field was input as properties material data of geometrical
model. The data includes weight of content, cohesion, and inner sliding angle.
Geotechnical modeling utilizes a support of software slide V6 by Rocscience.
This modeling is conducted all over the area of Highwall slope. All modeling are
simulated in the condition of half saturated except for the modeling of high level
change on the highwall slope.
From the analysis factors of the steepness stability, the results are : for
CW_A04, height 95,911 m, angle 20°, half saturated groundwater with FK value
(1,347) ; for CW _A07, height 93,977 m, angle 25°, half saturated groundwater
with FK value (1,230); for CW_B01, height 79,9976 m, angle 19°, half saturated
groundwater with FK value (1,357). Bishop Simplified method.
For CW_A04, height, height 95,911 m, angle 20°half saturated
groundwater with FK value (1,229), CW_A07, height 93,977 m, angle 25°, half
saturated groundwater with FK value (1,099). For CW_B01, height 79,9976m,
angle 19°, half saturated groundwater with FK value (1,200). Janbu simplified
method with critical criteria (
