      <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 during hydraulic mining of thick steeply dipping seams by the sublevel hydraulic extraction system, flexible metal floors are used, separating coal from the caved rock and, along with completeness of extraction, allowing coal extraction to be carried out without support in the stope.</p>
