Известно, что целик между буродоставочными выработками является одним из основных элементов подэтажной системы разработки и представляет собой область массива в пределах одного подэтажа, ограниченную по периметру выработками. Отмечено, что в настоящее время общепринятой для определения параметров целика является методика сравнения его несущей способности с действующими напряжениями; при этом не учитывается большое число факторов, характерных для условий апатит-нефелиновых месторождений. Кроме того, механизм разрушения целика в структурно нарушенных массивах не всегда соответствует теории разрушения опорного ядра. В связи с этим обоснована актуальность исследования зависимостей формирования напряженно-деформированного состояния целика с целью дальнейшей разработки алгоритма подбора его оптимальных параметров.
