INTRODUCTION
Deep tunnelling
for civil and mining applications poses many challenges for geologists, designers
and contractors. Whereas poor ground conditions and the influence of ground
water have been successfully handled by the tunnellers at relatively shallow
depth, and new innovative means have been found to manage poor ground conditions,
at great depth and under high stress, even good ground is less forgiving and
poses new problems.
Under these conditions, conventional methods of design and analysis are not always applicable or adequate to keep the risk of tunnelling at depth in acceptable limits. The success or failure of a tunnelling project is often inadvertently determined early in the design stage when excavation equipment and support methods are selected.
Mistakes made in the feasibility study stage can then only be overcome with great effort and cost. Much can be learned from experiences with mining at great depth where static and dynamic failure processes are controlled on a routine basis.
This course is intended for practising engineers and geologists that are faced with these challenges while tunnelling at depth in hard, brittle rock. The content of the course will also be of value to those involved in the geological characterisation and design of underground excavations, stopes, hydropower caverns and repositories in massive rock.
A series of hands
on computer tutorials will be a part of the course using Phase 2 and RocSupport
software.
As well, there
will be case studies presented by Sandvik Tamrock Canada.
