U radu se analizira razlika dobivena pri određivanju granulometrijskog dijagrama odminirane stijenke mase metodom sijanja i obradom slike za situaciju kada se fragmenti međusobno preklapaju. Ukratko je opisana tehnička analiza sijanja i analize slike. Pokazano je da se računalnim programom GoldSize dobivaju bliski rezultati onima koji se dobivaju sijanjem te da se taj program može vrlo uspješno primijeniti za određivanje granulometrijskog dijagrama odminirane stijenske mase.The difference obtained by determining grain size distribution diagram of the blasted rock mass by sieving method and by image processing, in situations when fragments are overlapping, is presented in the paper. The technical analysis of sieving and image processing is described in general terms. The authors demonstrate that results close to sieving results have been obtained by GoldSize program and that this program can successfully be used for determining grading of the blasted rock mass
