Decreasing ore losses and dilution can be achieved by controlling stress and strain using the residual bearing capacity of the broken rocks with the priority condition of preserving the earth's surface from collapse. The study aim is to substantiate rational parameters of mining methods based on the criterion of geodynamic safety. The aim is achieved by solving a set of mining tasks that ensures correctness of the obtained results, from assessing geotechnical condition to developing measures to prevent environmental impact of mining operations. The research methods include systematization and review of theory and practice, results of experimental studies and scientific forecasting. Importance of the mining system optimality criterion reflecting preserving the earth's surface from collapse to prevent contacting mining zone with habitat of beings (flora, fauna, and humans) has been substantiated. The mechanism of structural blocks interaction in discrete gravitational-tectonic-structural field has been detailed. The mechanism of broken rock blocks residual bearing capacity manifestation was clarified. The ways to increase the residual bearing capacity are: limiting the span size, optimizing strength of backfilling mixtures and pillar size to create geotechnically stable areas with minimizing the cost of managing the earth’s surface condition. Typification of methods for calculating spans of flat roof is proposed. Classification of rock mass management methods is given, the feature of which is assessing the worked out space condition as of pillar extraction completion, but not at the time of stoping. An example of the earth's surface preservation during mining of flat-dipping deposit with preservation of the earth's surface without backfilling the voids is given. Managing the condition of rock masses and the earth's surface above them allows monitoring of mining at all LoM stages. The use of geotechnical factors in organizing mineral extraction is a tool for implementing resource-saving and environmental-friendly trends in mining and a way to improve quality of ore mined while ensuring the enterprise competitiveness.</p></abstract><trans-abstract xml:lang="ru"><p>В условиях рыночной экономики особое значение приобретают показатели качества добываемого сырья. Уменьшение потерь и разубоживания руд может быть достигнуто путем управления напряжениями и деформациями при использовании остаточной несущей способности разрушенных пород с приоритетным условием сохранения земной поверхности от разрушения. Целью исследования является обоснование рациональных параметров технологий по критерию геодинамической безопасности. Цель достигается решением комплекса горнотехнических задач, обеспечивающих корректность полученных результатов, от оценки геомеханического состояния до разработки мер профилактики воздействия горных работ на окружающую среду. Методы исследования включают систематизацию и анализ теории и практики, результаты экспериментальных исследований и научное прогнозирование. Обосновано значение критерия оптимальности технологий разработки в виде сохранения земной поверхности от разрушения как гарантии от контакта зоны разрушения массива горными работами и зоны обитания живого вещества, флоры, фауны и человека. Детализированы представления о механизме взаимодействия структурных блоков в дискретном гравитационно-тектоническо-структурном поле. Уточнен механизм проявления остаточной несущей способности разрушенных структурных отдельностей пород путем ограничения величины пролетов, оптимизации прочности смесей и размеров целиков при создании геомеханически сбалансированных участков с минимизацией затрат на управление состоянием земной поверхности. Предложена типизация методов расчета пролетов плоской кровли. Дана классификация способов управления массивом, отличающаяся оценкой состояния выработанного пространства на время окончания работ по погашению, а не во время очистной выемки. Приведен пример сохранения земной поверхности при разработке пологопадающего месторождения с сохранением земной поверхности без заполнения пустот. Процессы управления состоянием массивов и земной поверхности над ними адекватны, что позволяет обеспечить мониторинг разработки месторождения на всех этапах существования предприятия. Использование геомеханических факторов при организации добычи минерального сырья является инструментом реализации ресурсосберегающих и природоохранных тенденций в горном производстве и резервом повышения качества добываемых руд при обеспечении конкурентоспособности предприятий</p></trans-abstract><kwd-group xml:lang="ru"><kwd>напряжения</kwd><kwd>порода</kwd><kwd>земная поверхность</kwd><kwd>технология</kwd><kwd>геомеханика</kwd><kwd>горные работы</kwd><kwd>окружающая среда</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stress</kwd><kwd>rock</kwd><kwd>earth's surface</kwd><kwd>technology</kwd><kwd>geotechnics</kwd><kwd>mining</kwd><kwd>environment</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Каплунов Д.Р., Радченко Д.Н.
