Outlook of ice excavation techniques
In earth boring it is common to circulate drilling mud in the bored hole. The two purposes of the circulation, besides removal of cuttings, are to cool cutters and to preserve the hole, which are both unimportant in ice boring. Hence, because of its light weight, a cable-suspended core drill which t...

The drilling time with a core drill is discussed in detail. An important problem in deep ice boring is the hole closure due to ice pressure.
