Book Description
Rockbolting: Principles and Applications brings current theoretical and practical developments in the most widely used support device for underground rock excavations. Today, one cannot find any rock excavation project that does not use rockbolts for rock support. The worldwide annual assumption of rockbolts is in the billions, with pieces applied to mines, tunnels and other types of geotechnical projects for rock and soil reinforcement. The text is based on over 25 years of experience of the author both as academic and practitioner. The book introduces the principles and background concepts of rock support, and then offers a comprehensive overview of the mechanics of rockbolting, as well as current rock bolt types such as mechanical, grouted, self-drilling, grouted cables, frictional and yield rockbolts. Installation and performance assessment are covered next including load-displacement curves and energy-absorption capacities. Two chapters on design and quality control, respectively, cover failure mechanics, the selection process and the connections with other supporting devices. On quality control, the author explains the usual tests and displacement measurements. The final chapter brings current case studies that combine the concepts presented in the whole book. The book is a professional reference for engineers in the mining and geotechnical industries and can be used as research material for academics in rock mechanics and stability studies. - Offers theoretical knowledge on rock bolts and rockbolting - Covers the standard and most recent types of rockbolts - Includes information on rockbolting in high stress rock - Presents case studies that introduce practical applications in several conditions

Book Description
This includes the Proceedings of the international symposium, Abisko, Sweden, 28 August-2 September 1983. Rock bolts today represent the dominant support system in mines and underground structures. Some results and experiences are discussed to give a better understanding of the strength of individual rock bolts and systems of bolts, and the interaction between bolts and rock masses of various types. Topics covered are as follows: rock bolting in theory and experiments; design principles and experience; and ground control and instrumentation: cable bolting.

Book Description
Since its inception two generations ago, oculoplastic surgery has constantly evolved. What was once dogma may now be passé. Procedures that were once passé may be resurrected and utilized again. Providing simplified solutions to complex problems, Atlas of Oculoplastic and Orbital Surgery is a practical, problem-orientated guide to the management of common oculoplastic and orbital disorders. Based on Dr. Spoor’s thirty years of practice, the book emphasizes the more common oculoplastic conditions likely to present to a busy ophthalmologist. The text covers upper and lower eyelid surgery and repair, orbital surgery, and the prevention and treatment of potential complications. The procedures are described with surgical photos and illustrations in a casual, didactic fashion, as a senior doctor would use instructing a resident or fellow. The book is essential reading for ophthalmologists, oculoplastic surgeons, neuro-ophthalmologists and plastic surgeons.

Book Description
All engineering structures react with the ground, and most structures make use of materials extracted from the earth. While an engineer cannot be expected to be also an expert geologist, he must have a working knowledge of the subject if his structures are to be economically designed, safely built and safely used. He must also be able to recognise where and when he needs the advice of a specialist. A Manual of Applied Geology is designed as a guide for practising engineers. A team of distinguished engineers and scientists has been assembled to present the basic information which an engineer needs and to explain how best to use this information to deal with problems in his work. Chaptes cover general theory, Formation of rocks, their properties and identification, landforms and soils, geophysical methods, maps and other information sources. the particular problems of terrain evaluation, site selection and investigation and common construction problems (including groundwater control, stability, foundations and underground work) are examined and there are chapters on materials and hydrogeology.Aimed principally at the engineer who is meeting geological problems in his everyday work, this generously illustrated volume will also be useful as an introduction to the subject for first degree engineering students
