Abstract
Osnovni cilj ovog rada je utvrditi u kojoj mjeri fizikalno-mehanička svojstva stijena utječu na energiju potrebnu za rezanje stijena, te analizirati zavisnost specifične energije drobljenja i specifične energije rezanja. Laboratorijska ispitivanja specifične energije rezanja provedena su na pet uzoraka različitog mineralnog sastava. Ispitivanja su provedena na uređaju za pravolinijsko rezanje stijena pri čemu su mjerene sve tri komponente sile rezanja. Specifična energija rezanja dobivena je iz omjera energije utrošene na rezanje i mase odlomka. Statističkom obradom podataka dobiveni su korelacijski odnosi prema kojima najveći utjecaj na specifičnu energiju rezanja ima tlačna čvrstoća. Na temelju dobivenih rezultata i rezultata prijašnjih ispitivanja određena je zavisnost specifične energije drobljenja o specifičnoj energiji rezanja.
Abstract (english)
Abstract: The main goal of this paper was to determine to what extent physical and mechanical properties of rocks affect the energy used for rock cutting and to analyze the dependence of the specific crushing energy on the specific cutting energy. The research activities of the specific cutting energy comprised 5 samples of different mineral compositions. Cuts on the samples were made by means of the linear cutting machine. After each cut all the three strength components were measured by means of the measurement converter. The specific cutting energy was obtained from the ratio between the energy used for cutting and the sample mass. The statistical data processing provided the correlation values, according to which the compressive strength has the highest impact on the specific cutting energy and the specific crushing energy. Based on the obtained results and the results of the previous research activities the dependence between the specific crushing energy and the specific cutting energy was determined.
