The world is going underground and a manifestation of that is the growth in tunnelling and underground space in and around our cities, the expansion in mines seeking underground resources, and the increase in hydroelectric power where man can build on the opportunities provided by nature. The present workshop brings together those involved globally in the construction of tunnels in rock, underground caverns, and underground space technology using the drilling and blasting method. Tunnel construction project managers and operators, mining and geotechnical engineers, underground space operators, government and regulatory authorities and end users and owners of the infrastructure created can review current and future technologies and benefit from the shared experience included in the proceedings. The topics covered in the workshop include drilling equipment, explosives and delivery systems used in tunnelling, and initiation systems including those based on electronic delay detonators. Modern methods of blast design for safe and rapid tunnelling given the challenges of the geological setting are discussed. Methods of assessing a tunnel blast outcome are canvassed with case studies that consider excavation and geotechnical issues based on the experience of the authors and presenters. Software is used in various parts of a tunnel construction and the workshop covers the current state of the art in this important and growing area. The workshop describes tools such as MWD (measurement while drilling) designed to aid the assessment of rock mass conditions ahead and around the tunnel heading. A significant consideration is the environmental effects of the tunnelling process and a number of approaches to assessing and predicting ground vibration from tunnel blasting are presented.
