        <p>Определение границ карьера — одна из основных задач проектиро­вания разработки месторождения. Ее решение обычно осуществляется в три стадии. Рассчитывается граничный коэффициент вскрыши, затем выбирается метод оконтуривания, и, наконец, по выбранному методу карьер оконтуривается.</p>

        <p>Determination of open pit boundaries is one of the main tasks of designing the field development. Its solution is usually carried out in three stages. The boundary stripping ratio is calculated, then the method of delineation is selected, and, finally, according to the selected method, the quarry is delineated.</p>
