Abstract: The range of rock pieces movement at mass blasts depends on the conditions of drilling and blasting operations, which, in turn, are determined by quite a few natural and technological factors. Quantitative assessment of the influence of each of these factors is a rather difficult task. Uncertainty is also introduced by the fact that most of the factors are interrelated, which additionally complicates the assessment of their influence on the size of the scattering. The variety of known and unexplored factors affecting the rock movement during the blast suggests the need to consider the range of movement as a value that has a probabilistic nature in its basis.
