Длительная эксплуатация карьера вызывает возникновение инженерно-геологических процессов: осыпей, обвалов, оползней, оплывин, суффозий. Развитие процессов, инициируемое технологическими работами, носит прогрессирующий характер в пространственно-временном отношении. Решение вопросов устойчивости бортов карьера, обеспечивающих безаварийное ведение горнодобывающих работ при длительной разработке месторождения, базируется на современной методологии расчёта. Предлагается алгоритм оптимизации углов заложения откосов Стойленского карьера и расчёт коэффициента устойчивости различными методами c учётом трещиноватости скального массива на основе использования критерия анизотропии прочности пород.</p></abstract><trans-abstract xml:lang="en"><p>The development of Stoylensky iron ore opencast mine during the 50 years is accompanied by the extraction of huge masses of rocks and ores, that radically changes the stress-strain state of the array and the formation of a technogenic aquifer. The long-term quarry exploitation has a result of progressive development of engineering-geological processes: scree, landslides, creeps, suffusion. The development of processes initiated by technological works has a progressive space-time character. The solution of problem of the open pit slope stability which provides accident-free conducting of mining operations at long-term development of the field, is based on modern methodology of calculations. The angles optimization algorithm of slopes staking on Stoylensky iron ore open cast mine and the calculation of the coefficient of stability by different methods with the consideration of the anisotropy of strength properties and fracture density of the solid rock, have been suggested.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>природно-техническая система</kwd><kwd>месторождение</kwd><kwd>карьер</kwd><kwd>откос</kwd><kwd>процессы</kwd><kwd>анизотропия</kwd><kwd>трещиноватость</kwd><kwd>устойчивость</kwd><kwd>модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>natural-technological system</kwd><kwd>field</kwd><kwd>quarry</kwd><kwd>slopes</kwd><kwd>processes</kwd><kwd>anisotropy</kwd><kwd>model</kwd><kwd>stability</kwd><kwd>fracturedensity</kwd><kwd>properties</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">Железные руды КМА: монография / под ред.
