The book is an excellent professional reference for geoscientists, technicians, and geological engineers doing research and consulting in mining, geological, civil, and petroleum resource fields.
Download or read book Support of Underground Excavations in Hard Rock written by E. Hoek and published by CRC Press. This book was released on 2000-01-01 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The safe and economical construction of tunnels, mines, and other subterranean works depends on the correct choice of support systems to ensure that the excavations are stable. These support systems should be matched to the characterstics of the rock mass and the excavation techniques adopted. Establishing the support requirements, designing support systems and installing these correctly are essential elements in safe underground construction. This is a comprehensive and practical work which also gives access to user-friendly computer programmes which enable the investigation and design of support techniques. Details on how to obtain this software are also included in the book.
Download or read book Engineering Rock Mass Classification written by R K Goel and published by Elsevier. This book was released on 2011-08-09 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rock mass classification methods are commonly used at the preliminary design stages of a construction project when there is very little information. It forms the bases for design and estimation of the required amount and type of rock support and groundwater control measures. Encompassing nearly all aspects of rock mass classifications in detail, Civil Engineering Rock Mass Classification: Tunnelling, Foundations and Landsides provides construction engineers and managers with extensive practical knowledge which is time-tested in the projects in Himalaya and other parts of the world in complex geological conditions. Rock mass classification is an essential element of feasibility studies for any near surface construction project prior to any excavation or disturbances made to earth. Written by an author team with over 50 years of experience in some of the most difficult mining regions of the world, Civil Engineering Rock Mass Classification: Tunnelling, Foundations and Landsides provides construction engineers, construction managers and mining engineers with the tools and methods to gather geotechnical data, either from rock cuts, drifts or core, and process the information for subsequent analysis. The goal is to use effective mapping techniques to obtain data can be used as input for any of the established rock classification systems. The book covers all of the commonly used classification methods including: Barton’s Q and Q’ systems, Bieniawski’s RMR, Laubscher’s MRMR and Hoek’s and GSI systems. With this book in hand, engineers will be able to gather geotechnical data, either from rock cuts, drifts or core, and process the information for subsequent analysis. Rich with international case studies and worked out equations, the focus of the book is on the practical gathering information for purposes of analysis and design. Identify the most significant parameters influencing the behaviour of a rock mass Divide a particular rock mass formulation into groups of similar behaviour, rock mass classes of varying quality Provide a basis of understanding the characteristics of each rock mass class Relate the experience of rock conditions at one site to the conditions and experience encountered at others Derive quantitative data and guidelines for engineering design Provide common basis for communication between engineers and geologists

Download or read book Development of Expert System for Rock Mass Classification and Support System written by Michael Neunhoffer and published by . This book was released on 1993 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: " The aim of this project was to create an expert system for the classification of rock masses and the selection of support for underground excavations. The algorithm has been written using VP-Expert. The algorithm in its current state could have been easily written in pascal but VP-Expert was used to allow for future modifications to the algorithm which may require the expert capabilities of VPExpert. The algorithm uses the Laubscher method of rock mass classification. There are three main parts to the algorithm: 1. Rock mass classification. This part of the algorithm asks for the rock characteristics to be entered so a rock mass rating (RMR) can be calculated. Before running this part of the program the core samples must be tested to find the strength and weathering properties of the rock. 2. Conditions of mining. A Mining Rock Mass Rating ( MRMR ) and a Design Rock Mass Strength (ORMS) are generated by this part of the algorithm. The MRMR takes into account the orientation of joints and bedding, blasting technique, stress concentration and the effects of exposing the rock surfaces. 3. Selection of support. The information entered and calculated in the first two parts of the algorithm is used to select a suitable form of support from a database of support systems. There are many areas for future expansion of the algorithm. For example, it could be made to read the geological information directly from a geological traverse and the stress concentrations directly from a stress analysis package. The algorithm could be modified to use custom databases for different localities. These areas have not been developed in the algorithm this year. " -- Abstract/Synopsis.

Book excerpt: Rock Mass Classifications - A Practical Approach in Civil Engineering was written in response to the many unanswered questions regarding this subject. Questions such as - Is Classification reasonably reliable? Can it be successful in crisis management of geohazards? Can a single Classification system be general for all rock structures? Is Classification a scientific approach? Laborious field research was undertaken in the Himalayan mountains by a team of scientists from the Central Mining Research Institute (CMRI), University of Roorkee (UOR), Central Soil and Material Research Station (CSMRS), U.P. Irrigation Research Institute (UPIRI), and Norwegian Geotechnical Institute (NGI) to answer these questions. The results obtained from the research work were systematically compiled to produce this book which bears particular relevance to civil, mining and petroleum engineers and geologists.

Download or read book Rock Mass Stability Around Underground Excavations in a Mine written by Yan Xing and published by CRC Press. This book was released on 2019-11-20 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stability of underground excavations is of great importance to an operating mine because it ensures the safety of the working people and operating equipment, and successful ore production. Due to the complex geological conditions and mine constructions, and variability and uncertainty in estimating rock mass mechanical properties, the assessment of rock mass stability for an underground mine is extremely challenging and difficult. Tackling of this difficult problem is not covered in detail in any of the textbooks currently available in the rock mechanics literature. This monograph aims to cover this gap in the rock mechanics and rock engineering field. This monograph provides detailed procedures for the stability assessment and support design for an underground mine case study. It covers the background of the mine site including the monitored deformation data, the state-of-art methodologies for the stability analysis of rock masses around underground excavations, performed laboratory tests, estimation of the rock mass properties, a brief theory and background of the 3-D Distinct Element Code (3DEC), and numerical modeling of underground rock mass stability including investigation of the effectiveness of rock supports. The monograph is an excellent reference for the senior undergraduates, graduate students, researchers and practitioners who work in the Underground Rock Mechanics and Rock Engineering area in the Mining Engineering, Civil Geotechnical Engineering and DEM (Distinct Element Method) Numerical modeling.
