Experimental test stand for studying investigation of borehole stability during drilling in glacial cover
Abstract
With the increase in drilling depths the borehole drilling in glacial cover becomes sharply complicated, as the borehole continuously narrows due to ice creep under conditions of increasing rock 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. ...
