o:1122 Calibration of excavator cutting force and energy consumption considering the impact of the overburden mechanical properties en Abstract: In present paper authors examine the impact of overburden mechanical properties on the cutting force and energy consumption of the bucket-wheel excavator at the opet pit mines. The conducted research consisted of two parts: experimental and analytical. Experimental phase included terrain and laboratory methods in order to determine the main properties of the overburden, as well as the performance of the excavator, at „Turija-Banovići“ case study. Analytical phase included the extensive statistical study of the obtained results, in order to detmine the impact of the examined overburden properties on the excavator performance. For this purpose, authors developed explicit mathematical models, where cutting force and energy consumption are represented as the linear function of statistically significant influential factors: unit weight, compressive strength and the cohesion of the overburden. Results obtained indicated that cutting force and energy consumption increases with the increase of unit weight, cohesion and compressive strength, while tensile strength and friction angle have statistically insignificant effect. cutting force, energy consumption, overburden, mechanical properties, statistical analysis 1552100 978-86-82673-21-7 2022-12-29T08:07:40.854Z 44 no 46 Jelena Trivan University of Banja Luka, Faculty of Mining Prijedor, Prijedor, Bosnia and Herzegovina Srđan Kostić Institut za vodoprivredu "Jaroslav Černi" person 0000-0002-3705-3080 Mirko Šalović University of Banja Luka, Faculty of Mining Prijedor, Prijedor, Bosnia and Herzegovina person application/pdf 705622 https://unilib.phaidrabg.rs/o:1122 no yes 1 70 92000004 71A04 8th Balkan Mining Congress, September 28-30, 2022, Belgrade 441 447 Mining institute Ltd., Belgrade 2022
