Some peculiarities of excavation of three flat seams strata using draglines

One of the methods increasing efficiency dragline operation is to optimize their work when mining end sections cuts. This especially important length front relatively short. With operations going deeper, and complication geological conditions bedding, it often becomes necessary mine shorter face sections. However, as a rule, design bureaus do not take into account visualize excavation sections, because these are, in fact, special cases standard schemes. Nevertheless, significantly complicates organization due need create routes for draglines ascend descend dump tiers. Scientific literature does pay enough attention this issue its complexity full-scale field experiment, which modern very problematic. article establishes relevance above-mentioned identifies directions further research.
