Установлено, что для изучения предельного состояния массива необходимо применять комплексный критерий. Определение такого критерия можно выполнить с использованием разработанных подходов. Первый подход заключается в выборе нескольких критериев, оценивающих предельное состояние массива по отдельным типам напряженно-деформированного состояния массива: критерия наибольших нормальных напряжений, критерия наибольших линейных деформаций, критерия наибольшего касательного напряжения, критерия Кулона–Мора. Второй подход заключается в построении объединенного критерия предельного состояния предлагаемого вида для материалов, у которых предельные величины напряжений на растяжение и сжатие отличаются существенным образом. При этом вводятся параметры, характеризующие вид напряженного состояния и свойства материала, которые в совокупности определяют характер разрушения – отрыв или срез. Для описания поведения горных пород в запредельной по прочности стадии деформирования предлагается применять деформационную теорию прочности с использованием разработанной зависимости деформационного критерия прочности. При расчете прочностных характеристик повторно подрабатываемого массива горных пород рекомендуется применять коэффициент структурного ослабления в виде произведения нескольких коэффициентов, учитывающих различные типы нарушения первично подработанного массива и временной фактор. Условие прочности Кулона–Мора рекомендуется использовать с учетом составного коэффициента структурного ослабления. Разработаны зависимости, описывающие изменение прочностных характеристик пород в подработанном массиве с учетом коэффициента разрыхления.</p></abstract><trans-abstract xml:lang="en"><p>Methodological approaches to the selection of ultimate state criteria and strength characteristics of the repeatedly undermined rock massifs were developed. These approaches were designed to provide parametric support to the geomechanical modelling of the massif stress-strain state and the mining systems of the Starobin potash deposit mine fields planned for the additional mining of the mineral reserves left. It was established that a complex criterion must be used to study the massif ultimate state. Determination of such criterion can be carried out using the developed approaches. The first approach is to select several criteria that evaluate the massif ultimate state by certain types of the massif stress-strain state. These criteria are the following: the criterion of the maximum normal stresses, criterion of the maximum linear strains, the criterion of the maximum shear stresses and the Coulomb–Mohr failure criterion. The second approach is to construct an integrated failure state criterion for materials whose ultimate tensile and compressive stresses differ significantly. In this case, parameters characterizing the type of stress state and properties of the material are introduced. These parameters together determine the destruction character – tear or shear. To describe the rocks behavior in the extreme strength stage of deformation, it is proposed to apply deformation theory of strength using the developed strain failure criterion. When calculating the strength characteristics of the repeatedly undermined rock massif, it is recommended to use a structural attenuation coefficient as the product of several factors, taking into account various types of disturbances in the primary undermined massif and the time factor. The Coulomb–Mohr strength condition is recommended to be used taking into account the composite structural attenuation coefficient. Dependencies have been developed to describe the change in the strength characteristics of rocks in the undermined massif, considering the attenuation coefficient.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>слоистый массив горных пород</kwd><kwd>механические характеристики</kwd><kwd>напряженно-деформированное состояние</kwd></kwd-group><kwd-group xml:lang="en"><kwd>layered rock massif</kwd><kwd>mechanical characteristics</kwd><kwd>stress-strain state</kwd><kwd>ultimate criteria</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">Rodionov V.
