      <abstract xml:lang="ru">
        <p>Для уменьшения потерь угля при гидравлической разработке мощ­ных крутопадающих пластов системой подэтажной гидроотбойки применяются гибкие металлические перекрытия, отделяющие уголь от об­рушенной породы и, наряду с полнотой извлечения, позволяющие вести выемку угля при отсутствии крепи в очистном пространстве.</p>

      <abstract xml:lang="en">
        <p>To reduce coal losses at hydraulic development of powerful steeply falling seams by the system of sub-stage hydraulic stripping flexible metal overlaps are used, separating coal from the collapsed rock and, along with the completeness of extraction, allowing to carry out coal excavation in the absence of fasteners in the clearing space.</p>
