This paper reviews some of the significant research accomplishments obtained under a 3-year, $66 million research program in rock mechanics and rapid excavation sponsored by the defense department advanced research projects agency (arpa) and managed by the Bureau of Mines. In addition to the rock mechanics research, five major phases of excavation--systems analysis, geologic prediction, rock disintegration, ground support, and materials handling--were represented by the projects funded under the arpa program.
