The application of photogrammetry analysis in the evaluation of muck pile fragmentation of Russian diamond and copper-nickel ore
mines was presented in the article. The evaluation was performed in the AutoCAD and Split Desktop 2.0 software based on the photographic
documentation of three different muck piles. Moreover, calculation of Hazen’s index which may be applied in Russia as an additional tool to
evaluate blasting works were included. According to performed analysis, it can be observed that the weighted average grain diameters for
Underground A and B were in the optimum range. Furthermore, Hazen’s index shows that all analysed muck piles should be evaluated as
non-homogenous. This could be explained by the type of exploitation system which was used during ore extraction.
