Описана предлагаемая авторами схема моделирования анкерного крепления линейными (1D) элементами методом конечно-дискретных элементов. Приведена методика, которую можно применять для обоснования параметров крепления выработок. В реальных условиях отработки месторождения выполнено сравнение трех схем численного моделирования для определения параметров искусственного поля напряжений. Показаны примеры моделирования напряженно-деформированного состояния массива вокруг выработок, когда действует неравнокомпонентное поле напряжений. Отражены особенности и преимущества предлагаемого подхода к расчету анкерных крепей.
