Summary:This paper analyses the stability of the design and construction of Kota Bunyih (KB) tailings dam of Rahman Hydraulic Tin Mine which is located at Kelian Intan, Pengkalan Hulu Perak. The stability assessment of KB tailings dam was conducted using 2D Limit Equilibrium Methods analysis software, Slide 6.0 from Rocscience Inc. using two different approaches - the deterministic and probability approaches. In the analyses, it was found that the upstream and downstream factors of safety (FOS) obtained through deterministic analysis are satisfactory as compared to the recommended minimum FOS for both normal operating freeboard and flood freeboard conditions. In addition, both of the normal and lognormal reliability index values obtained from overall slope surface analysis are twofold the minimum recommended value, which indicate the satisfactory level of safety of KB tailings dam slope.
