        <p>Как известно, на устойчивость целиков существенное влияние оказывают неоднородность пород, наличие различного рода прослойков, включений и льда. Для уточнения этого влияния в лаборатории горного давления ЛГИ в 1963—1967 гг. был проведен комплекс исследований, включающий изучение несу­щей способности целиков со слабыми прослойками других по­род и включениями льда для условий Аркагалинского, Сангарского, Джебарики-Хая месторождений угля и сланцевского месторождения Прибалтики...</p>

        <p>As it is known, the stability of pillars is significantly affected by the heterogeneity of rocks, presence of various layers, inclusions and ice. In order to clarify this influence in the Laboratory of Mining Pressure of LMI in 1963-1967 a set of studies was carried out, including the study of bearing capacity of pillars with weak interlayers of other rocks and ice inclusions for the conditions of Arkagalinskoye, Sangarskoye, Dzebariki-Khaya coal deposits and Baltic shale deposits...</p>
