Бенявски и распределения массовой трещиноватости. Для оценки инженерно-геологических условий глубоких горизонтов месторождения использовались данные, полученные в процессе геомеханической документации керна при проходке разведочных и гидрогеологических скважин и документации стенок подземных горных выработок. Это позволило оценить степень раздробленности пород массива, влияющую на устойчивость подземных горных выработок. По отобранным пробам пород из керна разведочных скважин и горных выработок выполнен полный комплекс определений физико-механических и деформационных свойств. Всего в течение полевого сезона отобрано и проанализировано 184 пробы и выделено 10 разновидностей пород, характеризующихся различной прочностью, и, как следствие, степенью устойчивости. Проведенный сравнительный анализ на примере Ирокиндинского месторождения позволяет говорить о необходимости комплексного применения этих методик с целью повышения достоверности результатов и максимально корректного определения класса устойчивости горного массива для проходки в нем горной выработки. Результаты, полученные по различным методикам, должны рассматриваться как набор сигналов для принятия проектных решений об укреплении горных выработок.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of the study is to compare and adjust the results of stability forecast for Irokinda gold deposit underground mine workings using various estimation methods of rock mass state based on the analysis of structural parameters only, multiparameter classification of structural parameters and engineering-geological indicators according to Z. Bieniawski as well as mass fracturing distribution. Engineering and geological conditions of deposit deep horizons have been estimated using the data obtained under geomechanical description of the core when drilling exploratory and hydrogeological boreholes and description of the walls of underground mine workings. All these made it possible to estimate the rock mass fragmentation degree, which affects the stability of underground mine workings. A full range of physical, mechanical and deformation property definition was performed using rock samples taken from the core of exploratory boreholes and mine workings. A total of 184 samples have been taken and analyzed during the field season with distinguishing of 10 rock varieties characterized by different strength and stability degree. The comparative analysis conducted on the example of the Irokinda field implies the need of the integrated use of these methods, which will enable increasing of result reliability and most accurate determination of the stability class of the rock mass for its further mining. The results obtained by various methods should be considered as a set of signals for making design decisions on strengthening mine workings.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>классификации</kwd><kwd>массив горных пород</kwd><kwd>геомеханическая документация</kwd><kwd>классы устойчивости</kwd><kwd>инженерно-геологические показатели</kwd><kwd>трещиноватость</kwd><kwd>структурные параметры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>classifications</kwd><kwd>rock mass</kwd><kwd>geomechanical documentation</kwd><kwd>stability classes</kwd><kwd>engineering and geological parameters</kwd><kwd>fracturing</kwd><kwd>structural parameters</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">Кузьмин Е.В., Узбекова А.Р.
