AbstractA contract was placed for the construction of a 7.6 m- diameter rock tunnel boring machine. Disk cutters or rippers can be employed as dictated by the rock conditions. All cutter changes are effected from within the machine. The first 1.5 km of a 14.5 km tunnel with a 20% decline were completed at the Donkin-Morien Mine, Nova Scotia. The average rate of advance of the machine was 1.8 m/h and its usage has been quite satisfactory.
