Abstract

Slopes in mining activities require analysis and calculation because dangerous slopes will cause landslides that can endanger workers. In slope analysis, the overburden stripping process which uses the blasting method affects the stability of the slope. The stability of a slope which is influenced by the vibration of the blasting results is the reason why the researcher did the research. Analyze slope stability using Rocksceince Slide v.6 software. Slope stability will be analyzed according to the safety factor standard where FK> 1.25 is stable. The initial analysis is static where without the influence of vibration, namely only density, cohesion, and internal shear angle. The FK analysis results were in a static state, namely section A1 1.886; section A2 2,171; section B1 1,984; section B2 2,004; section C1 2,323; section C2 1,648. Pseudo-Static Analysis by adding blasting vibration results, namely the seismic acceleration of the longitudinal wave where the acceleration used is 0.058 (g). The results of the analysis in a pseudo-static state, namely section A1 1.575; section A2 2,171; section B1 1,677; section B2 1,700; section C1 1,946; section C2 1,402.
