Abstract
Directional drilling technology can be used in glacier boreholes to obtain additional ice cores and to pass over sticking drills. Experimental sidetracking of 5G-2 hole in the deep borehole at Vostok station, Antarctica, showed the high efficiency of the directional drilling without using of special whip-stocks to deviate the hole.
