      <abstract xml:lang="ru">
        <p>Первые решения задачи о бурении с одновременным заморажива­нием проходимых пород, сводящейся к отысканию связи между глуби­ной фронта замораживания и механической скоростью бурения, носят приближенный характер и содержат параметры, определяемые из опыта или произвольно.</p>

      <abstract xml:lang="en">
        <p>The first solutions to the problem of drilling with simultaneous freezing of passable rocks, which is reduced to finding the relationship between the depth of the freezing front and the mechanical speed of drilling, are approximate and contain parameters determined from “experience" or arbitrarily.</p>
