Characterization of the distribution of physical and mechanical properties of rocks at the Tutupan coal mine, South Kalimantan, Indonesia

摘要

Uncertainties of factors that influence slope stability have been acknowledged by many geotechnicalrnengineers, and these are drawn from the characterization of the geotechnical parameters of the slope. Therncharacterization is associated with a process of identifying the distribution of random variable values used inrnthe design of a single slope of an open mine, and also part of the probabilistic method which is an alternativernapproach in estimating the stability of a slope with a Failure Probability value (FP). This paper explains the characterizationrnprocess using the Kolmogorov-Smirnov (K-S) method, which will determine the most appropriaternfunction for the distribution of the random variable. The characterization results can be used in determining thernSafety Factor including the level of confidence and Probability of Failure based on the best fitting function.
