Abstract
Bucket wheel excavators are machines that on the current level of surface mining development have gained the widest application. Its work consists of the main movements (slewing of the bucket wheel and superstructure) and auxiliary movements (moving of the excavator toward advance direction and modification of the height position for the bucket wheel in the vertical plane).The support of the bucket wheel (bucket wheel boom) is the most loaded part of the excavator structure participating with 6 to 13% to the complete excavator weight. Depending on the soil-mechanic properties of the deposit, as well as mining technology, it is selected the optimal parameters of the excavator and therefore the required boom length, of course with the optimization of economic indicators.This paper provides comparative analysis of the BW boom length influence on the technical parameters of the block as well as on the capacity of different types of excavators.KeywordsAdvance DirectionTechnical ParameterMining TechnologySide SlopeCentral PillarThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
