As a Geotechnical Engineer Internship Student for 6 months in PT Bayan Resources Tbk, I have completed my final project on slope stability analysis, studying site lithology, coal channel sampling, staking out IUP limits, surveying topo and stockpile volumes with real-time kinematic, supervising mining progress, analyzing the rock structure and determining slip surface using DIPS, calculating rock mass rating, slopes modeling, analyzing data distribution of physical and mechanical properties of rocks for the probability of failure (PoF) analysis, analyzing mine slope stability using the Mohr-Coulomb and Hoek and Brown failure criterion, analyzing disposal stability, exercising minescape, SLIDE, DIPS, and Matlab software, as well as processing data and making weekly slope monitoring reports with Slope Stability Radar (SSR-XT).
