Deep Core Drilling: Electro-Mechanical or Thermal Drill?

Abstract

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.
