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.

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.

Rock Blasting and Explosives Engineering covers the practical engineering aspects of many different kinds of rock blasting. It includes a thorough analysis of the cost of the entire process of tunneling by drilling and blasting in comparison with full-face boring. Also covered are the fundamental sciences of rock mass and material strength, the thermal decomposition, burning, shock initiation, and detonation behavior of commercial and military explosives, and systems for charging explosives into drillholes. Functional descriptions of all current detonators and initiation systems are provided. The book includes chapters on flyrock, toxic fumes, the safety of explosives, and even explosives applied in metal working as a fine art. Fundamental in its approach, the text is based on the practical industrial experience of its authors. It is supported by an abundance of tables, diagrams, and figures. This combined textbook and handbook provides students, practitioners, and researchers in mining, mechanical, building construction, geological, and petroleum engineering with a source from which to gain a thorough understanding of the constructive use of explosives.

The only modern guide to all aspects of practical tunnelconstruction Practical Tunnel Construction fills a void in theliterature for a practical guide to tunnel construction. By takingthe reader through a brief introduction and history to acomprehensive discussion of how the geological factors affecttunneling, the author covers the stages and technology that arecommon today without using complex equations. Written for theindividual who does not have an extensive background in tunnelingbut who has to make tunneling decisions, the various tunnelingmethods are discussed to help in the determination of theappropriate method. The methods discussed are: hand mining,drill/blast, Tunnel Boring Machine (TBM), New Austrian TunnellingMethod (NATM), Norwegian Method of Tunnelling (NMT), Roadheader,Earth Pressure Balance Machine (EPBM), and Slurry Pressure BalanceMachine (SPBM). This book focuses on driven tunnels. This versatile handbook: Offers clear and accessible coverage of the state of the art intunnel construction Introduces the essentials of design and construction of manytypes of tunnels, including TBM, EPB, Roadheader, NATM, drill andblast, and soft ground tunneling Provides nontechnical guidance on selecting the mostappropriate tunneling methods for various situations Includes a brief history of tunneling and an introduction togeotechnical considerations Discusses tunnel access shaft construction, mucking methods,tunnel haulage, grout, water handling, and much more Practical Tunnel Construction is an important resourcefor students, construction managers, tunnel designers, municipalengineers, or engineers who are employed by government agencies orcorporations that are exploring the feasibility of planning anddesigning or building a tunnel.

Bei der Festlegung von Straßentrassen und Bahnstrecken werden heute umweltverträgliche Lösungen gefordert. Dies hat dazu geführt, dass der Tunnelbau im Fels- und Lockergestein einen großen Aufschwung erlebt. Die Anforderungen an diese Ingenieurdisziplin, aber auch ihre technischen Möglichkeiten, sind vielfältiger geworden. Für die erfolgreiche Durchführung von Tunnelbauprojekten haben die Verfahrenswahl und die baubetriebliche Abwicklung einen hohen Stellenwert erhalten. In dem vorliegenden Buch werden sämtliche Bauverfahren für die Planung und Durchführung moderner Tunnelbauwerke, ausgehend von der geologischen Situation, vorgestellt. Vortriebsarten und -verfahren, Spezialtunnelbauverfahren, Logistiksysteme, Baustelleneinrichtung und Fertigungsanlagen werden detailliert erläutert. Dabei wurde großer Wert auf die Interaktion mit den Nachbardisziplinen Geologie, Felsmechanik, Werkstoffkunde, Maschinenbau und Betriebswirtschaft gelegt, um den Baubetrieb in den Gesamtbauprozess einzubetten. Für die 2. Auflage wurde das Werk aktualisiert und um Berechnungsbeispiele ergänzt. Damit bildet es für Praktiker, Neueinsteiger und Studenten gleichermaßen eine wertvolle Arbeitshilfe.
