        <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>

        <p>The first solutions to the problem of drilling with simultaneous freezing of the rocks being penetrated, which reduces to finding the relationship between the depth of the freezing front and the mechanical rate of drilling, are approximate and contain parameters determined from experiment or arbitrarily.</p>
