      <abstract xml:lang="ru">
        <p>Существующие способы отбойки при системах с массовым обрушением, как правило, характеризуются значительным вы­ходом крупнокусковой руды (свыше 250—350 мм). Это хорошо видно на примере рудников комбината Апатит. В табл. 1 при­веден выход кусков различной крупности в зависимости от ме­тода отбойки...</p>

      <abstract xml:lang="en">
        <p>The existing methods of stripping in mass caving systems are usually characterized by a significant yield of large lump ore (over 250-350 mm). This is well illustrated by the example of Apatit mines. Table 1 shows the yield of lumps of various sizes depending on the method of stripping...</p>
