Abstract (english)

Load factors, defined as portion of utilized engine power, are used in estimation of the diesel mining equipment fuel consumption. Every type of equipment is involved in the specific work operation, common in quarrying of crushed stone. Furthermore, load factors are specific for the equipment type and their application/operating conditions. Based on the mining company’s empirical data on fuel consumption, load factors of the main equipment in quarrying of crushed stone are determined in this paper. This includes bulldozer, backhoe excavators, wheel loaders, trucks, blasthole drill, mobile crushing and screening plants, and mobile belt conveyor. With an assumption of similar operating conditions, those factors can be considered as characteristic for small quarries of crushed stone, but also for mining on other surface pits, depending on the specific equipment application. The obtained load factors are compared to the available data from other sources in order to verify the results and establish the appropriate procedure for assessment of unknown load factors in different operating conditions.

Abstract (croatian)

Koeficijenti opterećenja, definirani kao udio nazivne snage pogonskog motora angažirane pri radu, koriste se pri procjeni potrošnje goriva rudarske mehanizacije. Svaka vrsta mehanizacije koristi se u specifičnom radnom procesu pri eksploataciji tehničko-građevnog kamena. Koeficijenti opterećenja karakteristični su za vrstu stroja i radni proces/uvjete rada. Prema empirijskim podacima potrošnje goriva koncesionara, u ovome radu su određeni koeficijenti opterećenja pogonskih motora glavnih strojeva pri eksploataciji tehničko-građevnog kamena. Ovo uključuje dozer, bagere, utovarivače, kamione, bušaću garnituru, pokretna postrojenja za sitnjenje i klasiranje, te pokretni tračni transporter. S pretpostavkom sličnih radnih uvjeta, dobiveni koeficijenti opterećenja mogu se smatrati karakterističnima za male kopove tehničko-građevnog kamena, ali i ostale površinske kopove, zavisno o primjeni mehanizacije. Dobiveni koeficijenti opterećenja uspoređeni su s drugim izvorima radi verifikacije rezultata i određivanja pogodne procedure procjene nepoznatih koeficijenata opterećenja u nepoznatim radnim uvjetima.
