In this survey of tunnel boring machines and associated equipment and methods, those systems favored in current practice for economic and/or performance reasons are pointed out, along with some new concepts which have special applicatins. The survey covers types of machines, support systems, types of cutters, grade and size limitations, the influence of rock hardness, transport systems, ventilation systems, alignment control, and current investigations both in the laboratory and in the field. Among the investigations underway are studies on disc cutter performance by the Colorado School of Mines and the Bureau of Mineral Resources in Minnesota, and a research operation in the United Kingdon whereby an instrumented full-scale tunnel is being bored in chalk by the Tunnels Division of the Transport and Road Research Laboratory.
