      <abstract xml:lang="ru">
        <p>Представлено горно-технологическое обоснование полного извлечения кондиционных руд из сложноструктурных блоков уступов путем примешивания слоя некондиционных руд определенных размеров. Актуальность работы состоит в разработке инновационных методов установления параметров некондиционного слоя руд, примешиваемого к кондиционным. Основной проблемой является обеспечение полного извлечения полезных компонентов в концентрат из отгруженной руды с допустимыми отклонениями от требуемых. Проведена новая типизация сложноструктурных рудных блоков уступа. Получены аналитические зависимости горно-геологических характеристик сложноструктурных рудных блоков. Выведены теоретические зависимости для определения основных показателей обогащения полезных ископаемых. Предложены аналитические зависимости для определения содержания полезного компонента в отгружаемой руде α' – смеси кондиционной руды с содержанием полезного компонента α и примешиваемого слоя некондиционной руды с содержанием полезного компонента α''. Впервые в горной науке обоснован новый подход полного извлечения кондиционных руд из сложноструктурных блоков уступов за счет прихвата определенной части некондиционных руд при выемке, повышающий объем извлекаемой руды и расширенное извлечение полезных компонентов в концентрат. Приращение полезных компонентов может достичь 10-15 % от общего объема добычи, что позволяет прогнозировать существенное повышение полноты извлечения полезных ископаемых из недр Земли.</p>

      <abstract xml:lang="en">
        <p>The paper presents mining-technological substantiation of complete extraction of conditioned ores from complex-structured blocks of benches by mixing a layer of substandard ores of certain sizes. The relevance of the work consists in the development of innovative methods of establishing the parameters of the substandard layer of ores to be added to the conditioned ores. The main problem is to ensure complete extraction of useful components into concentrate from shipped ore with acceptable deviations from the required ones. A new typification of complex-structured ore blocks of the bench has been carried out. Analytical dependences of mining and geological characteristics of complex-structured ore blocks were obtained. Theoretical dependences for determining the main indicators of mineral processing are derived. Analytical dependences for determination of the content of useful component in shipped ore α' – mixture of conditioned ore with the content of useful component α and admixed layer of substandard ore with the content of useful component α'' are offered. For the first time in mining science, a new approach of complete extraction of conditioned ores from complex-structured blocks of benches by grabbing a certain part of substandard ores during excavation, increasing the volume of extracted ore and expanding the extraction of useful components in the concentrate has been substantiated. The increment of useful components can reach 10-15 % of the total volume of extraction, which allows predicting a significant increase in the completeness of mineral extraction from the Earth's interior.</p>
