Приведены результаты математического и физического моделирования торцового выпуска руды для подземной геотехнологии подэтажного обрушения. Описаны основные особенности корректного проведения лабораторных экспериментов на эквивалентных материалах и численных решений методом дискретных элементов. Установлены устойчивые связи изменения показателей извлечения от конструктивных элементов выпуска руды, позволяющие отдавать предпочтение параметрам, обеспечивающим минимальные потери и разубоживание руды. Изучено влияние глубины выемки на показатели извлечения.
