Представлены результаты геотехнического анализа площадки кучного выщелачивания при сооружении дополнительных ярусов с целью извлечения дополнительных объемов руды. Кратко описаны полевые исследования, выполненные на начальном этапе строительства, и дано описание проведенного на их основе геотехнического моделирования. Для оценки устойчивости откосов и выявления потенциальных геотехнических рисков применена комбинация двухмерного и трехмерного моделирования (методы предельного равновесия и конечных элементов). Установлено, что результаты 3D-моделирования могут определять отличные от 2D-методов механизмы деформации с более низкими коэффициентами запаса устойчивости. Оценено влияние крутизны основания на устойчивость откосов площадки, продемонстрированы результаты спутникового мониторинга устойчивости откосов.
