In most cases, this is dictated by the high rate of a pit deepening and multi-stage development. In this study, the energy intensity of rock mass (RoM) haulage from the working zone of a pit to the surface is considered at several hierarchical levels. Mineframe software was used to study 3D-models of open pits with different slope angles in order to test the method of analytical calculation of a pit volume that allowed ensuring accuracy under a wide range of mining conditions. The findings of the research are as follows: with an increase in the pit bottom diameter, the zone of stabilization of rock mass lifting (haulage) height shifts to greater target depths. An increase in the pit slope angles entails shifting the weighted average height to deeper elevations. By increasing the pit target depth, combined modes of transport become more economical in comparison with dump trucks due to an increase in the total volume of rock mass. Depending on the comparison purpose, it was proposed    to use different types of energy intensity. For a broad estimation of the rationality of the pair “scheme of opening – mode of transport” for open pits, the ratio of potential energy intensities of rock mass haulage   of a considered option of a pit opening and its basic option without transport berms was used. The ratio of potential energy intensities as a function of a pit depth was determined. The values of total energy intensity of rock mass haulage from a pit to the surface were also established.</p></abstract><trans-abstract xml:lang="ru"><p>Значительная часть месторождений полезных ископаемых, разрабатываемых открытым способом, вскрывается автомобильными транспортными съездами на всю глубину без использования комбинированного транспорта. В большинстве случаев это связано с высокой скоростью снижения уровня горных работ и многоэтапной разработкой. Методы исследований энергоемкости транспортирования горной массы из рабочей зоны карьера на поверхность рассматриваются в несколько иерархических уровней. Для исследования 3D-моделей карьеров с различными углами откоса использовано программное обеспечение Mineframe с целью забазировать методику аналитического расчета объема карьера, что позволило обеспечить точность при широком охвате диапазона горнотехнических условий. При увеличении диаметра дна карьера зона стабилизации высоты подъема смещается к большим конечным глубинам, увеличение угла откоса бортов карьера влечет за собой смещение средневзвешенной высоты в глубину,  с ростом конечной глубины карьера комбинированные виды транспорта становятся более экономичными в сравнении с автомобильным за счет увеличения суммарного объема горной массы. В зависимости от цели сравнения предложено использовать различные виды энергоемкости, для укрупненной оценки рациональности пары «схемы вскрытия – вид транспорта» для карьеров возможно использовать отношение потенциальных энергоемкостей перемещения горной массы рассматриваемого варианта вскрытия карьера и его базовой версии без транспортных берм, установлены закономерности изменения отношения потенциальных энергоемкостей от глубины карьера, определены значения полной энергоемкости транспортирования горной массы из карьера до поверхности комбинированными видами транспорта.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>энергоёмкость</kwd><kwd>транспортная система карьера</kwd><kwd>глубокий карьер</kwd><kwd>схема вскрытия</kwd><kwd>транспортная берма</kwd><kwd>карьерные автосамосвалы</kwd><kwd>угол откоса бортов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>energy intensity</kwd><kwd>open pit haulage system</kwd><kwd>deep pit</kwd><kwd>opening scheme</kwd><kwd>transport berm</kwd><kwd>pit dump trucks</kwd><kwd>slope angle</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследования выполнены в рамках Государственного задания Минобрнауки РФ №075-00412-22 ПР</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The research was performed within the framework of the State Assignment of the Ministry of Education and Science of the Russian Federation No. 075-00412-22 PR</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Яковлев В.
