. "The cutting edge (blade) geometry and the cutting edge (blade) material are key influences for efficiency and energy demands of the bucket wheel excavator mining processes in brown coal open pit mines. The frequent exchange of the cutting edges (blades) causing by wear and tear or break is the cause of increasing of mining processes energy demands and reduction of excavator working time, i.e. lower productivity of the equipment complex. The basic thought of this paper is dealing with relation and association of bucket wheel excavator cutting edge (blade) geometry and corresponding energetic demands, life time, position in bucket, termographic image and blade material in typical mining and geological conditions of the North Bohemian coal basin. We use measuring devices and evaluation methods. The blade wear and frequency of blade exchange optimization is expected output." . "10.5593/sgem2014B13" . . "2014-01-01+01:00"^^ . . .
