Zusammenfassung:Method of open-pit development of steeply-dipping plate-like mineral deposits includes run of the pit field by extraction excavator blocks connected to each other by transport platforms and safety platforms. Thee pit field along the deposit is beforethat separated to parts for extraction excavator blocks, at that in the process of mining works at the laying side of the bed the blocks are shifted forward with respect to the areas of blocks at the overhang side to distance not less than the length of car descent from one terrace to another. Development of minerals is performed in long direction from the run end of the pit, with permanent transport communications, to the other one.
