At the same time key factors, including those influencing mining safety, should be comprehensively taken into account. A developed rock burst forecasting technique taking into account mine workings of an extraction area and a mine goaf enables determining the safe direction of a coal face. The proposed technique also takes into account all faulting/joint systems, occurring beyond a mine field. The distribution of specific potential energy in an intact rock mass is proposed to be used as the basis of the input data required for rock burst forecasting. The forecast is carried out via estimating the Lode-Nadai coefficient at different directions of coal face advancing. The stress (intensity) coefficient is proposed to be used as a criterion in order to determine a safe direction. We determined the safety criterion is equal to 10 in the Komsomolskaya Mine conditions. Besides, the safest direction of a coal face advance to mitigate the risks of rock burst was determined for this mine. The direction between 138° and 128° counter-clockwise from the north direction was identified to be the safest for the Komsomolskaya Mine conditions for any values of deformation modulus and Poisson’s ratio.</p></abstract><trans-abstract xml:lang="ru"><p>Планирование горных работ связано с выбором оптимальных решений по раскройке шахтного поля. При этом необходимо комплексно учитывать основные факторы, влияющие в том числе на безопасность ведения горных работ. Разработанная методика прогноза горных ударов в процессе ведения горных работ, учитывающая горные выработки выемочного участка и выработанное пространство, позволяет определить безопасное направление фронта очистных работ. Предлагаемая методика учитывает также все геологические нарушения, которые находятся и за пределами шахтного поля. В основе исходных данных, необходимых для осуществления прогноза горных ударов, предлагается использовать распределение удельной потенциальной энергии в нетронутом массиве. Прогноз осуществляется путем оценки параметра Надаи–Лоде (Lode–Nadai coefficient) при различных направлениях движения фронта очистных работ. Для определения безопасного направления предлагается в качестве критерия использовать коэффициент напряженности. В статье определен критерий безопасности для условий ш. Комсомольская, равный 10. Также для данной шахты было определено направление фронта очистных работ, при котором существенно снижаются риски проявления горных ударов. Наиболее безопасным для условий ш. Комсомольская является вариант направления между 138° и 128° против часовой стрелки от Северного направления для любых реализаций модуля деформации и коэффициента Пуассона.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>угольная шахта</kwd><kwd>безопасность</kwd><kwd>горный удар</kwd><kwd>прогноз</kwd><kwd>выемочный участок</kwd><kwd>алгоритм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coal mine</kwd><kwd>safety</kwd><kwd>rock burst</kwd><kwd>forecast</kwd><kwd>extraction area</kwd><kwd>algorithm</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">Malinnikova O., Uchaev D., Uchaev D., Malinnikov V.
