DISPLACEMENT AND STRESS ANALYSIS AT BISMA PIT SLOPE, SATUI, SOUTH KALIMANTAN WITH DISTINCT ELEMENT METHOD (UDEC)

In mining area, surface or underground, Occupational Safety and Health (K3) is a very important matter. For surface mining, one thing we must always watch is the slope stability. Slope at the surface mine influenced by driving forces and resisting forces. If the resisting forces larger than the resi...

For surface mining, one thing we must always watch is the slope stability. Slope at the surface mine influenced by driving forces and resisting forces. If the resisting forces larger than the resisting forces, the slope will stay stable. But if the driving forces larger than the resisting forces, the slope is not safe and slop failure might happen. Hence, we need to do an analysis to see the possibility of the failure. In here the analysis is numeric method analysis by using computer program based on distinct element method which called Universal Distinct Elemen Code (UDEC). The research took place at the highwall slope face of Bisma Pit, Satui, South Kalimantan owned by PT Arutmin Indonesia. The result of this research shows that the maximum horizontal displacement occur at the bottom-most part (toe) of the highwall slope. The displacement value is 0.19 meters. Maximum vertical displacement occur at the crest of the slope which the value is 0.838 meters. The average value of major principal stress (σ1) is 766.6 kPa and 328.5 kPa for the minor principal stress (σ3). The average value of horizontal stress (σxx) is 520.4 kPa, while the average value of vertical stress (σyy) is 311.7 kPa. The safety factor is quite varied from 1.1 to 4.95. At the bottom part of the slope, there are some points with relatively small safety factor. This may causes local failure at the toe part and may disrupts the overall slope stability. text
