Abstract
Kako bi se smanjila potreba za naknadnim usitnjavanjem stijenske mase, te povećala efikasnost pri drobljenju stijenske mase, potrebno je utvrditi optimalne parametre miniranja kojima utječemo na veličinu i razdiobu fragmenata stijenske mase. Ostvarivanje povoljne fragmentacije odminirane stijenske mase ima izravan utjecaj na povećanje rentabilnosti kamenoloma i površinskih kopova. Fragmentiranje stijene ovisi o strukturnim i fizičko-mehaničkim značajkama stijenske mase prema kojima odabiremo vrstu eksploziva i geometriju bušenja. Za prognoziranje fragmentacije najčešće se koristi Kuz-Ram model, opisan u ovom radu, koji je, zbog svoje jednostavnosti i mogućnosti proširivanja kod različitih situacija miniranja, jedan od najprimjenjivanijih modela u inženjerskoj praksi. Za ostvarivanje bolje prognoze fragmentacije koriste se rezultati dobiveni pokusnim sijanjem ili fotografskom analizom fragmentacije stijenske mase kojima se postiže bolje razumijevanje strukturne građe stijenske mase. U radu će biti prikazana usporedba prognozirane fragmentacije Kuz Ram modelom ,te fotografske analize računalnim programom „Wip-Frag“ na primjeru utvrđivanja fragmentacije prilikom probnih miniranja na eksploatacijskom polju tvrtke Cemex Hrvatska d.d. iz Splita.
Abstract (english)
In order to reduce the need for subsequent blasting of rock mass and increase the efficiency of rock mass grinding, it is necessary to establish optimal mining parameters that affect the size and distribution of rock mass fragments. The realization of favorable fragmentation has a direct effect on the increase of profitability in open pit mines and quarries. Fragmentation of a rock depends on the structural, physical and mechanical characteristics of the rock mass according to which we choose the type of explosives and drilling geometry. For the prediction of fragmentation, the most commonly used Kuz-Ram model, described in this thesis, is one of the most applicable models in engineering practice, due to its simplicity and ability to expand in different minefield situations. For better prediction of fragmentation, the results obtained by sieving or by photographic analysis of rock mass fragmentation are used to achieve a better understanding of the rock mass structure. In this thesis, a comparison of the predicted fragmentation of the Kuz Ram model and the photographic analysis of the computer program "WipFrag" will be presented on the example of fragmentation determination during mining probes on the exploitation field of Cemex Hrvatska d.d. from Split.
