Tunnelling in Rock by Drilling and Blasting presents the latest developments in the excavation of tunnels using the drilling and blasting method. Examples of work conducted throughout the world including the Indian sub-continent, Australia, and Sweden amongst others are discussed. These tunnel projects serve to illustrate the challenges and importance of drilling accuracy, the effect of geology, methods of vibration prediction and control, and techniques for assessing tunnel performance in terms of overbreak and underbreak, advance and rock mass damage. A number of case studies demonstrate the ingenuity required to successfully excavate tunnels in demanding circumstances. Finally, an overview is provided of the software tools and IT, and the explosives and initiation products used to implement tunnel blast designs. Tunnelling in Rock by Drilling and Blasting is the outcome of the workshop, Tunnelling in Rock by Drilling and Blasting, hosted by the 10th International Symposium on Rock Fragmentation by Blasting (Fragblast 10, November 2010, New Delhi, India), and is essential reading for researchers and practitioners in tunnelling in rock by drilling and blasting.

Tunneling in Rock reviews the theory and practice of engineering geology and its application to tunneling in rocks. This book explores the history of tunneling, defines terminologies of tunneling, and illustrates tunnels. The book discusses the petrography of unaltered rocks, such as rock minerals, fragmental rocks, igneous rocks, sedimentary rocks and metamorphic rocks. The book then describes rock alteration, which may be caused by weathering. Such alterations are low-temperature alterations at moderate depths, hydrothermal alteration, deuteric alteration, pneumatolytic alteration, and other miscellaneous types of alteration. The book also discusses elementary rock mechanics, such as isotropism and anisotropism; mechanical properties of rocks; force and stress; and the fracture and fold anisotropy in rocks, including the deformation of minerals, elastic, quasi-elastic, and plastic rocks. The remaining chapters of the book focus on hydrogeology; geological investigation of proposed tunnel locations and its application to tunnel planning and design; different tunneling methods; and geological investigations during tunnel constructions. Those who are interested in geological aspects of planning and constructing tunnels will find this book valuable.

Rock breakage with explosives has existed since the seventeenth century when black powder came into use in mining. Since then it has progressed from the invention of dynamite to the use of heavy ANFO. During the past two decades, there have been numerous technical contributions which have brought a better understanding of rock fragmentation with explosives, an improvement in drilling equipment and a noticeable evolution in the development of new explosives and blasting accessories. The Geomining Technological Institute of Spain (ITCE), aware of this progress and of the importance which the breakage process has acquired in mining and civil engineering projects, has ordered the publication of Drilling and Blasting of Rocks. The purpose of this Handbook is to give basic knowledge of the drilling systems, the types of available explosives and the accessories and the parameters that intervene in blast designing, whether controllable or not; at the same time the objectives and contents contribute to improved safety in mining. The Handbook is meant for all professionals who are involved with explosives in mining operations and civil engineering projects, as well as for students of technical schools.
