    (Wydawnictwa AGH, 2009) Kozioł, Wiesław; Machniak, Łukasz
    The paper describes geological and qualitative characteristic of hard workable rocks on a example of lignite deposit »Bełchatów«. The analyses methods of rocks workability classification with BWE were executed. The attention was paid to development the technology using compact bucket wheel excavators with high digging forces. Auxiliary technologies like too: hydraulic excavators, surface miner, rippers and hydraulic rammers were also introduced. These technologies can pick up efficiency of excavation hard workable rocks.
