Application of Photogrammetry Analysis and Hazen’s Index in Evaluation of Muck Pile Fragmentation Obtained in Russian Ore Mines

Abstract

The application of photogrammetry analysis in evaluation of the muck pile fragmentation of Russian diamond and nickel ore mines was presented in the article. The evaluation was per-formed in the Split Desktop 2.0 software based on the photographic do - cumentation of three different muck piles obtained from the last phase of sublevel caving. Moreover calculation of the Hazen index which may be applied in Russia as an additional tool to evaluate blasting works was included. According to performed analysis it can be observe that the average grain diameters were in the optimum range. Furthermore the Hazen index shows that all analyzed muck piles should be evaluated as various grain size. This could be explained by the type of exploitation system which was used during ore extraction.
