| Description: | Technical Report Abstract: The excavations made by the ice tunnel project during 1956 demonstrated the feasibility of construction of large openings within the Greenland Ice Cap. The room excavated contained 2500 yd^3, had 3600 ft^2 of floor space, and a 25-ft height. No limiting size for an opening in ice was determined. The extension of the tunnel indicated that an overburden depth has been reached where hand methods of tunnel driving are not practical. This overburden depth is approximately 160 ft. In view of the difficulty encountered, either explosives or automatic coal mining machinery will be needed for deeper excavations. The mechanics of the glacier, with respect to openings, indicated that an excessive deformation does not occur at the overburden depth of 180 ft reached in the tunnel extension. |
