Abstract: The article presents the results of sensitivity analysis to the change of the probability distribution type of the duration of technological processes in the simulation modeling of stripping mining operations for the conditions of six open-cut mines in Kuzbass, as well as the results of the study of 280 samples of the duration values of the main technological processes of excavator-automobile complexes and the identification of the distribution laws of these values. Examples of analyzing the sensitivity of the model to changes in the distribution law of the main technological processes, as well as identifying the type of distribution in the modeling of stripping mining operations in the conditions of Kedrovsko-Krokhalevsky coal deposit are described in detail.
