The CRREL South Pole Tunneling System
Facilities operations in a polar ice cap environment present many challenges. Coping with the temperatures, associated wind chills, darkness during the long winter months, and blowing and drifting snow all hamper installation, maintenance, and repair. For over 40 years, the concept of using tunnels...

For over 40 years, the concept of using tunnels for utilities and personnel has been tried with mixed results.

The tunneling system as configured during the January 1996 deployment was capable of operating at a maximum sustained production rate (>4 hr) of 1.5 m/hr for a 2 x 3 x 116 m3 tunnel. The maximum operating depth was approximately 16 m from surface to the tunnel floor. The maximum length tunneled during one shift was 13 m, and the maximum one-day progress was 21.3 m.
