Deep Core Drilling: Electro-Mechanical or Thermal Drill?

In 1977/78 at Dome C, Antarctica, it was not possible to drill deeper than 905 m because of hole closure. The thermal drill was subsequently been modified to drill deeper in a fluid filled hole. Simultaneously, we have developed an electro-mechanical drill which employs a centrifuge device for separ...

Description
Summary:In 1977/78 at Dome C, Antarctica, it was not possible to drill deeper than 905 m because of hole closure. The thermal drill was subsequently been modified to drill deeper in a fluid filled hole. Simultaneously, we have developed an electro-mechanical drill which employs a centrifuge device for separating chips and drilling fluid. Both sets of equipment are described, as well as the main results obtained in the first tests made in Adelie Land in 1981/82. This article is from 'Proceedings of the International Workshop/Symposium on Ice Drilling Technology (2nd) Held at Calgary, Alberta, Canada on 30-31 August 1982,' ADA156733, p81-84.
