Предложена методика расчета несущей способности анкеров, применяемых для крепления поверхностей выработок. Оценка напряженного состояния стержня, установленного в шпур, выполнена по схеме нагружения, основанной на инженерном подходе. Принятая схема взаимодействия «стержень анкера – шпур» подтверждена специальными макетами шпуров. На основе верифицированной схемы нагружения разработана аналитическая зависимость несущей способности от параметров стержня анкера. Методика расчета позволяет оценить влияние каждого параметра стержня анкера на его несущую способность. Обоснована необходимость использования для изготовления стержня анкера стали с пределом текучести более 310 МПа.
