COPING WITH DIFFICULT GROUND ON THE FULLFACE MECHANISED TUNNEL DRIVES AT KIELDER

The article describes the performance of the demag and robbins fullface tunnelling machines used on the keilder water scheme transfer works. The machines have achieved record advance rates of up to 172 M per week during construction of the 28 km of 3.5 M diameter hard rock tunnels. The tunnelling operations encountered mixed beds of faulted rock and sections of bad ground conditions. The author discusses how it is possible to overcome such difficult tunnelling conditions without having to withdraw the fullface machines altogether. /TRRL/
