Tunnel engineering is one of the oldest, most interesting but also challenging engineering disciplines and demands not only theoretical knowledge but also practical experience in geology, geomechanics, structural design, concrete construction, machine technology, construction process technology and construction management. The two-volume "Handbuch des Tunnel- und Stollenbaus" has been the standard reference for German-speaking tunnellers in theory and practice for 30 years. The new English edition is based on a revised and adapted version of the third German edition and reflects the latest state of knowledge. The book is published in two volumes, with the first being devoted to more practical themes of construction and construction process in drill and blast and mechanised tunnelling. Microtunnelling and ventilation are also dealt with. All chapters include practical examples.

 The first comprehensive work on one of the most important underground mining methods worldwide, Geotechnical Design for Sublevel Open Stoping presents topics according to the conventional sublevel stoping process used by most mining houses, in which a sublevel stoping geometry is chosen for a particular mining method, equipment availability, and work force experience. Summarizing state-of-the-art practices encountered during his 25+ years of experience at industry-leading underground mines, the author:

    Covers the design and operation of sublevel open stoping, including variants such as bench stoping
    Discusses increases in sublevel spacing due to advances in the drilling of longer and accurate production holes, as well as advances in explosive types, charges, and initiation systems
    Considers improvements in slot rising through vertical crater retreat, inverse drop rise, and raise boring
    Devotes a chapter to rock mass characterization, since increases in sublevel spacing have meant that larger, unsupported stope walls must stand without collapsing
    Describes methodologies to design optimum open spans and pillars, rock reinforcement of development access and stope walls, and fill masses to support the resulting stope voids
    Reviews the sequencing of stoping blocks to minimize in situ stress concentrations
    Examines dilution control action plans and techniques to back-analyze and optimize stope wall performance

Featuring numerous case studies from the world-renowned Mount Isa Mines and examples from underground mines in Western Australia, Geotechnical Design for Sublevel Open Stoping is both a practical reference for industry and a specialized textbook for advanced undergraduate and postgraduate mining studies.

 This book contains a careful analysis of geological and environmental issues and a correct reconstruction of the conceptual model
This leads to optimal design solutions
This book presents a synthesis of current knowledge about all the issues needed to ensure the safety to the workers during construction and to the users

The construction of tunnels involves the resolution of various complex technical problems depending on the geological and geological-environmental context in which the work fits.

Only a careful analysis of all the geological and geological-environmental issues and a correct reconstruction of the conceptual model can lead to optimal design solutions from all points of view (including financial) and ensure the safety of workers during the construction and users in the operation phase.

It was therefore felt that there was a need to collect in one volume the state of current knowledge about:
•all the geological and environmental issues related to the construction of underground works
•the different methodologies used for the reconstruction of the conceptual model
•the different risk typologies that it is possible to encounter or that can arise from tunnel construction, and
•the most important risk assessment, management and mitigation methodologies that are used in tunneling studies
