In this book, the authors present a review of the methods used for the solution of problems of stability and support of mine workings, based on the study and analysis of the validity conditions of individual theoretical computing procedures. The classification of these methods, based on the analysis of factors determining the behaviour of a system of mine openings, should contribute to the greater objectivity of decisions connected with the management and control of mining operations and, from the educational point of view, enable the intricate problems of stability to be better understood. Chapters dealing with support structures and technologies of support review the present state of the art with special reference to problems prevailing in Europe where mining is carried out under continuously deteriorating and less favourable natural conditions. The authors have assembled the theoretical and practical knowledge necessary for those to whom the book is addressed, namely, practising mining engineers and project managers, and students and graduates in mining colleges and schools.

Lifeline earthquake engineering is the application of all relevant knowledge and skill to provide economically feasible engineering safeguards for critical systems such as energy, transportation, water, power, communications, etc. Natural gas and oil pipelines, water and sewage lines, oil and gas storage facilities, tunnels, power, voice and data communication lines and equipment are some of the recognized examples in this relatively new area of interest which has attracted an ever-increasing number of researchers in the past few years. This volume contains most of the papers on lifeline earthquake engineering which were presented at the Third International Conference on Soil Dynamics and Earthquake Engineering, Princeton University, Princeton, New Jersey, USA, 22-24 June 1987. A number of recent major developments in analytical/experimental investigations and field observations for buried pipelines, underground structures and storage tanks were presented by some of the leading experts from the United States, Japan and China.

Advances in Rock-Support and Geotechnical Engineering brings together the latest research results regarding the theory of rock mechanics, its analytical methods and innovative technologies, and its applications in practical engineering. This book is divided into six sections, rock tests, rock bolting, grouted anchor, tunneling engineering, slope engineering, and mining engineering. Coverage includes fracture hinged arching process and instability characteristics of rock plates, failure modes of rock bolting, scale effects, and loading transfer mechanism of the grouted anchor. Also covered are recent innovations and applications in tunneling engineering, slope engineering, and mining engineering. This book provides innovative, practical, and rich content that can be used as a valuable reference for researchers undertaking tunneling engineering, slope engineering, mining engineering, and rock mechanics, and for onsite technical personnel and teachers and students studying the topics in related universities. Enriches new theories on failure modes of rock plates, rock bolting mechanisms, and anchor loading transfer Develops new methods of evaluating the stability of slope engineering and the roof stability of the mined-out areas Includes fracture hinged arching process and instability characteristics of rock plates, failure modes of rock bolting, scale effects, and loading transfer mechanism of the grouted anchor

In this fully up-to-date volume, important new developments and applications of discrete element modelling are highlighted and brought together for presentation at the First International UDEC/3DEC Symposium. Papers covered the following key areas: * behaviour of masonry structures (walls, bridges, towers, columns) * stability and deformation of tunnels and caverns in fractured rock masses * geomechanical modelling for mining and waste repositories * rock reinforcement design (anchors, shotcrete, bolts) * mechanical and hydro-mechanical behaviour of dams and foundations * rock slope stability, deformation and failure mechanisms * modelling of fundamental rock mechanical problems * modelling of geological processes * constitutive laws for fractured rock masses and masonry structures * dynamic behaviour of discrete structures. Numerical Modelling of Discrete Materials in Geotechnical Engineering, Civil Engineering, and Earth Sciences provides an ultra-modern, in-depth analysis of discrete element modelling in a range of different fields, thus proving valuable reading for civil, mining, and geotechnical engineers, as well as other interested professionals.

This edited volume includes all papers presented at the 22nd International Conference on Mine Planning and Equipment Selection (MPES), Dresden, Germany, 2013. Mineral Resources are needed for almost all processes of modern life, whilst the mining industry is facing strict requirements regarding efficiency and sustainability. The research papers in this volume deal with the latest developments and research results in the fields of mining, machinery, automatization and environment protection.

Geotechnical Engineering For Mine Waste Storage Facilities

The book is a comprehensive treatment of the application of geotechnical engineering to site selection, site exploration, design, operation and closure of mine waste storage facilities. It has been developed from the official mining industry guide to the design and operation of tailings and waste rock storage facilities in South Africa, and also from a series of post graduate courses that have been taught at the University of the Witwatersrand, Johannesburg for many years. The level and content are suitable as a technical source and reference for practising engineers engaged both in the design and operational management of mine waste storage facilities and for senior undergraduate and postgraduate students. The thirteen chapters follow the sequence of the life cycle of a waste storage facility and also consider the use of mine waste as a construction material. The text is liberally illustrated by both line drawings and photographs, and the theoretical passages are supported by typical test results, worked examples and carefully analysed case histories.
