| Summary: | Blocks 18 and 21 in Pit 4 Asamasam mine of PT Arutmin Indonesia, South <br />
<br />
Kalimantan, have a weak material that can affect the stability of the low wall. It is <br />
<br />
therefore a necessary to continuously evaluate the stability of the low wall. <br />
<br />
PT Arutmin Indonesia Site Asamasam had done one of preventive action through <br />
<br />
dewatering as an alternative to reduce the driving force on the mining slope (low <br />
<br />
wall) at Blocks 18 and 21. The significance of dewatering action was then tested <br />
<br />
by doing a slope modeling with GeoStudio SLOPE/W GEO-STUDIO International <br />
<br />
Ltd. software with limit-equilibrium slicing method type Morgenstern-Price. <br />
<br />
Groundwater elevation was being measured by Piezometer. <br />
<br />
The slope modelling revealed that lowering the groundwater level can improve the <br />
<br />
stability of the low wall. A higher improvement is expected at Block 21 in <br />
<br />
comparison to Block 18. <br />
