State of the Art in Rock Fragmentation
Over the last decade the major development in rock fragmentation has been the growth in the use of mechanical excavation equipment either full face with tunnel boring machines or through use of the more flexible roadheaders. Recent technical developments, such as the swinging head TBM, are being introduced to maintain the momentum of development of these techniques. A more dramatic innovation has, however, been the introduction of waterjets at high pressure into tunnelling machines as a means of improving cutting performance. High Pressure Waterjet cutting systems have been developed and introduced into the market place for use in small hole drilling, as an assistance in cutting for both TBM and roadheaders, and for volume excavation in their own right.
