      <abstract xml:lang="ru">
        <p>Проблема снижения издержек производства за счет его интенсификации осо­бенно остро стоит в добывающих отраслях, где высоки темпы прироста добычи и обеспечение потребностей народного хозяйства на экстенсивной основе стано­вится все более затруднительно.</p>

      <abstract xml:lang="en">
        <p>The problem of reducing production costs through its intensification is especially acute in the extractive industries, where the rate of increase in production is high and providing the needs of the national economy on an extensive basis is becoming increasingly difficult.</p>
