        <p>Наиболее часто границы открытых работ определяют по равенству контурного коэффициента вскрыши экономически допустимому, который находят сопоставлением добычи открытым и подземным способом. Однако при значительной мощности наносов такая методика может привести к неверным выводам, так как определяемые по ней границы не учитывают горнокапитального объема, необходимого для пуска карьера в эксплуата­цию и зависящего от мощности наносов ...</p>

        <p>The most common way of determining the boundaries of open pit operations is to determine whether the contour stripping ratio is equal to the economically acceptable one, which is found by comparing open pit and underground mining. However, in the case of significant sediment load, this methodology can lead to incorrect conclusions, since the boundaries determined according to this method do not take into account the mining capital required to put the open pit into operation, which depends on the sediment load ...</p>
