Tunneling with Controlled Stress Waves.

Abstract

This report describes a concept for hard rock tunneling that uses controlled stress waves to fracture rock. Tests with high explosive charges demonstrated the feasibility of the concept, but follow-on tests with an electrohydraulic stress wave source were unsuccessful. Development of a repeatable stress wave source is necessary to the success of the concept. Extrapolations of test data indicate that the concept could reduce the specific energy requirements for hard rock tunneling by an order of magnitude compared to present tunnel boring machines.
