      <abstract xml:lang="ru">
        <p>Изучение и промышленное освоение ресурсов морского дна невозможно без технических средств и, в первую очередь, подводного горного оборудования. Важная роль среди подводных горных машин отводится донным агрегатам, несу­щим на себе добычные и геолого-разведочные рабочие органы в виде всасываю­щих наконечников, рыхлителей, ковшей, подборщиков, отвалов, грунтовых на­сосов, эрлифтных головок, зондов, крыльчаток, штампов и др.</p>

      <abstract xml:lang="en">
        <p>Exploration and industrial development of seabed resources is impossible without technical means and, first of all, underwater mining equipment. An important role among underwater mining machines is assigned to these units carrying mining and geological exploration working bodies in the form of suction tips, rippers, buckets, picks, dumps, soil pumps, erlift heads, probes, impellers, dies, etc. The main role of these units is played by the underwater mining equipment.</p>
