The optimum utilisation of energy supplied to the excavator wheel rests upon the optimisation of mode parameters of breaking aimed at diminishing the energy demand of the mining process at keeping theoretical efficiency. With bucket wheel excavators, the mining process is subject, similarly to any process in the course of which rock breaking takes place, to general regularities influencing the final...
VŠB-Technical University of Ostrava, institute of geodesy and mine surveying has been cooperating with Severočeské doly j.s.c. (SD) in important research project since 2007. The main goal is improve control system for opencast mining. Two bucket wheel excavators (K800/103 and KU300/27) were equipped with measurement hardware at the Libouš Lignite Mine (North Bohemia brown coal basin). The position...
The shape and the geometry of a bucket edge, its material and the material of a mechanical tooth are the key influences on the efficiency and energetic demands of mining processes with bucket wheel excavators. If the excavator units are often changed due to wear or breaking down, it increases the cost of the mining process, of course. It also reduces the service life of the machine and therefore it...
