Paper traces the development of tunneling methods up to the present day machines that can excavate up to 1,000 ft per week. Today the problems and the timeframe in which to reach solutions are different, and there is an urgency that is far greater than in the past. Some research and development projects of special promise include large-scale material handling systems including transport of tunnel muck hydraulically as a slurry, excavation by water cannon and by thermal-mechanical fragmentation, rock melting, pumpable, liquid rock bolts, continuous lining operations, and various kinds of stress measurement and analysis and roof deformation studies.
