      <abstract xml:lang="ru">
        <p>Направление углубки карьера характеризуется следом перемещения в карьерном пространстве, по мере понижения работ, места заложения первоначальной подготовительной выработки на каждом из горизонтов. Для определения рационального направления углубки был использован графо-аналитический метод, предложенный А. И. Арсентьевым и Г. А. Советовым. За критерий оптимальности принят минимум среднего с начала разработки коэффициента вскрыши, при котором достигается минимум приведенных затрат на строительство и эксплуатацию карьера. Цель исследования — проверить применимость методики при определении направления углубки для карьеров со сложными геологическими и топографическими условиями разработки, а также выявить особенности углубки таких карьеров.</p>

        <p>The direction of deepening of the quarry is characterized by the path of movement in the quarry space, as the works are lowered, the place of the initial preparatory excavation at each of the horizons. The graph-analytical method proposed by A. I. Arsentiev and G. A. Sovetov was used to determine the rational direction of deepening. The minimum of the average overburden ratio since the beginning of development is taken as the criterion of optimality, at which the minimum of the present costs of construction and operation of the open pit is achieved. The purpose of the study is to verify the applicability of the methodology in determining the direction of deepening for quarries with complex geological and topographical conditions of development, as well as to identify the features of deepening of such quarries.</p>
