Abstract:

Some of the recently developed ice-drilling hardware has been derived and developed from commercial equipment designed for drilling and coring in rock. The exceptions to this are the specially designed hydro-thermal and electro-thermal drills and corers, which have been developed on sound thermodynamic principles. The hydrothermal, or hot water drilling jet method, which is also applicable to drilling in geomaterials other than ice, has met with great success in rapidly penetrating glaciers and shelf ice even at temperatures well below the freezing point.
