Caused by the increasing geophysical and glaciological field investigations in polar regions more and more drill holes in cold firn and ice are required. Using hot water drilling a fast drill hole production is possible. Existing evaluations for hot water drills were derived from drill tests in temperate ice for small hole diameters. The present paper shows a possibility, based on thermal calculations in ground engineering to evaluate the necessary hear and the drill rate dependent on:
For quick estimates some graphs for fixed hole diameters are given.
