Выполнен анализ вариантов анкерного закрепления поверхности выработок. Установлено, что современным требованиям удовлетворяют конструкции, обладающие несущей способностью, существенно превышающей 50 кН. При этом анкер должен обладать допустимой величиной удлинения при действии предельной нагрузки (более 300 мм). Отмечено, что анкеры с фрикционным закреплением типа Split set отличаются высокой технологичностью установки и невысокой стоимостью. Однако по таким параметрам, как несущая способность, удлинение под нагрузкой, существенно уступают другим типам. Рассмотрена конструкция фрикционного анкера, обеспечивающая перераспределение несущей способности по длине за счет использования пружинной вставки в головной его части. Определен механизм взаимодействия стержня анкера со шпуром. Представлены результаты исследований анкера на макете шпура и в шахте ООО «ЕвроХим-ВолгаКалий». Установлена возможность повышения несущей способности усовершенствованной конструкции фрикционного анкера.
