1995年和1996年在南极洲的Dome Fuji从1993年安装的套管底部进行了深冰芯钻探，1996年12月达到2503.52米。我们使用JARE型机电钻机，岩心筒长2.2米。冰芯和碎片收集的总数分别为1369和837。每次运行和每天的平均取芯深度分别为1.75 m和8.21 m。冰芯的质量在整个深度上都是完美的，即使在脆性区也是如此。本文介绍了该系统的概况、取心性能和遇到的问题。
Deep ice core drilling was carried out at Dome Fuji, Antarctica in 1995 and 1996 from the bottom of the casing installed in 1993 and reached 2503.52 m in December 1996. We used a JARE type electromechanical drill with a core barrel of 2.2 m length. Total numbers of ice corings and chip collections were 1369 and 837 respectively. The mean coring depths per run and per day were 1.75 m and 8.21 m, respectively. Quality of ice cores was perfect throughout the whole depth, even in the brittle zone. We report the outline of the system, coring performance, and troubles encountered.
