Рассматриваются особенности отработки калийных месторождений — обязательное сохранение водозащитной толщи, проведение операций по минимизации проседаний земной поверхности. Указанные требования, а также мероприятия по утилизации отходов обогатительной фабрики можно реализовать с помощью обратной закладки. Рассмотрены основные виды и способы осуществления такой закладки. Представлена технология послойной механизированной обратной закладки в два этапа: основной, с помощью сухой транспортировки отходов обогатительной фабрики, и дозакладочный, когда верхняя часть камеры дозакладывается твердеющей смесью, приготовленной непосредственно вблизи нее, что позволяет достигать высоких прочностных характеристик массива. Разработан набор оборудования, который впоследствии можно собрать в единый мобильный комплекс. Описана перспектива использования таких комплексов в условиях подводной добычи твердых полезных ископаемых.
