The access tunnels for the Donkin-Morien Mine in Cape Breton, Nova Scotia comprise two parallel tunnels driven through a sedimentary sequence of sandstone, siltstone and mudstone to intersect the Harbour Coal Seam under the Atlantic Ocean, approximately 3.5 km offshore. / During the period May 1983 to December 1984, a geotechnical research programme was carried out in the Donkin-Morien tunnels by Golder Associates Ltd. The research programme included the monitoring of the performance of the TBM and drill and blast drivages, and the study of the thrusting characteristics and rock-interaction of the TBM excavation. The main emphasis of the research programme was on the collection of field data, which was to be made available in the form of a comprehensive report. The information gained from the programme was also used during the tunnel drivages to monitor the performance of the installed support and enable changes in the support and advance methods. / Throughout the research programme the author was resident on site at the Donkin-Morien Mine and was responsible for all aspects of the research project.
