| Abstract |
A borehole for sewage disposal was drilled at Asuka Station (71o31'34"S, 24o08'17"E, 930m a. s. l.) in January 1987. The borehole, 400mm in diameter and 27.5m in depth, was drilled 50m distant from the main hut using a steam drilling system. The drilling speed was 4m/h between the snow surface and 20m depth. The total amount of kerosene used for melting snow and steam generation was 110/. Sewage stored in the tank was directed to the borehole through a heated pipe. The cumulative amount of sewage was 1077k/ for 5 years, and the bottom of the hole rose 14m. |
