Download or read book The Strength Fracture and Workability of Coal written by Ivor Evans and published by Elsevier. This book was released on 2013-10-22 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Strength, Fracture and Workability of Coal deals with the strength of coal and the way in which various aspects of strength enter into the processes of mechanical winning. This book aims to provide rationalization of the design of coal winning machines for use in British mines and an increase of efficiency in existing machines. This book is composed of 14 chapters, and begins with a description of a stratified structure comprising a number of components of coal. This topic is followed by detailed measurements on a bituminous and an anthracite coal using static and dynamic techniques. The subsequent chapters are devoted to the definition and determination of coal's mechanical properties, such as compressive, tensile, and routine strength, particle size distribution, breakage, friction, and wedge penetration. The concluding chapters cover the mechanics of certain possible modes of interaction of coal and tool. These chapters also examine the theoretical aspects of the cutting and ploughing of coal. This book will prove useful to coal mining engineers, designers, and researchers.

Book excerpt: Crack Control: Using Fracture Theory to Create Tough New Materials goes beyond just trying to understand the origin of cracks and fracture in materials by also providing readers with the knowledge and techniques required to stop cracks at the nano- and micro-levels, covering the fundamentals of crack propagation, prevention, and healing. The book starts by providing a concise foundational overview of cracks and fracture mechanics, then looks at real-life ways that new tougher materials have been developed via crack inhibition. Topics such as crack equilibrium, stress criterion, and stress equations are then outlined, as are methods for inventing new crack-resistant materials. The importance of crack healing is emphasized and cracks that grow under tension, bending, compression, crazing, and adhesion are discussed at length as well Provides a better understanding of crack formation in various materials allowing for more efficient investigations of crack-based material or structural failure Demonstrates how to prevent cracks by arresting them at the nano- and micro-levels Looks at methods for developing new tougher and stronger materials through crack inhibition Emphasizes the importance of crack healing and explains crack stopping through changing the peel shape in various ways

Blasting technology is also discussed. along with water supply, oil and gas storage, the disposal of radioactive wastes, and the effects of mining on the surface environment. This book is comprised of 15 chapters and begins with a look at rock excavation by blasting, with emphasis on the blasting action of an explosive charge in solid material as well as the process of detonation in a high explosive. Vibrations and noise generated by blasting and other engineering processes are also considered, along with the techniques used in rock and earth excavation such as down-the-hole drilling, rotary rock drilling, roller-bit drilling, and rotary-percussive rock drilling. The following chapters focus on rock ripping and cutting; rapid tunnelling; the environmental and engineering aspects of the movement and control of groundwater; underground storage of oil and gas; pillar support of underground excavations; and ground-reinforcement techniques. The final chapter is devoted to ground movement, caving, and subsidence.
