For the simulation, the Mohr - Coulomb elastic-plastic model was used, as well as physico-mechanical properties of coal and host rocks. The simulation was carried out for specific mining and geological conditions of k2 anthracite seam occurrence. In a software module, several stages were simulated, allowing to determine magnitude of stresses and displacements of the roof in stopes at various stages of abutment pressure formation in front of the advancing stoping face. As a result of the simulation, the values of the stresses and displacements of the roof in the rock mass around the stopes at various stages of the development of the abutment pressure formation zones were obtained, enabling using the experimental design method to optimize the parameters of adjustable pillar (as support structure). These studies are aimed at improving efficiency of stope protection by optimizing the parameters of protective support structures (adjustable pillars) to increase productivity of the stoping face during excavation of flat-lying anthracite seams, including rockburst-dangerous ones.</p></abstract><trans-abstract xml:lang="ru"><p>В статье представлены комплексные исследования формирования зон опорного давления в геомеханической системе «парные штреки», включающие численное моделирование, основанное на методе конечных элементов. Для моделирования использовались упругопластическая модель Мора-Кулона, а также физико-механические свойства угля и вмещающих пород. Моделирование проводилось для конкретных горно-геологических условий залегания антрацитового пласта k2. В одном программном модуле моделировались несколько стадий, позволяющих определить величину напряжений и смещений кровли в выемочных выработках на различных этапах формирования опорного давления впереди движущегося очистного забоя. В результате моделирования получены значения напряжений и смещений кровли в массиве вокруг выемочных выработок при различных стадиях проявления зон опорного давления, позволяющие применить метод планирования эксперимента для оптимизации параметров охранной конструкции в виде податливого целика. Данные исследования направлены на повышение эффективности охраны выемочных выработок путем оптимизации параметров охранных конструкций (податливого целика) для повышения производительности очистного забоя при отработке пологих антрацитовых пластов, в том числе опасным по горным ударам.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>опорное давление</kwd><kwd>парные штреки</kwd><kwd>податливый целик</kwd><kwd>охрана выемочных выработок</kwd><kwd>антрацитовые пласты</kwd><kwd>ударобезопасность</kwd><kwd>численное моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>abutment pressure</kwd><kwd>paired drifts</kwd><kwd>adjustable pillar</kwd><kwd>stope protection</kwd><kwd>anthracite seams</kwd><kwd>rockburst safety</kwd><kwd>numerical simulation</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">Бажин Н.
