        <p>С увеличением глубин бурения проходка скважин в ледниковом покрове резко осложняется, так как непрерывно сужается ствол вследствие ползуче­сти льда в условиях возрастания горного давления и температуры. Так, при глубоком бурении на станции Восток в Антарктиде ползучесть льда стала проявляться с глубины 500 м при температуре льда -53°С ...</p>

        <p>With the increase of drilling depths the borehole penetration in the glacial cover becomes sharply complicated, as the borehole continuously narrows due to ice creep under the conditions of increasing mountain pressure and temperature. Thus, during deep drilling at the Vostok station in Antarctica, ice creep became apparent from a depth of 500 m at an ice temperature of -53°C. ...</p>
