A Theoretical and Experimental Study of Tunnel Boring by Machine with an Emphasis on Boreability Prediction and Machine Design
Abstract
The report discusses the results of the first year of a proposed three year program. The three year program was to perform small and full size linear cutting tests to determine scaling factors relating thrust, torque, specific energy, and cutting coefficient for two linear rock cutting machine sizes used. Also to be studied would be the relative efficiency of various cutter types, particularly roller versus pick type cutters. The main objective of the first year of the contract was the construction of the full size linear cutting machine. Construction and initial testing was successfully completed.
