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.

Available in PDF, EPUB and Kindle. Book excerpt: The secret to streamlined project scheduling is a solid understanding of basic rock cutting mechanics. Comparing theoretical values with experimental and real-world results, Mechanical Excavation in Mining and Civil Industries explains rock cutting theories for chisel, conical, disc, and button cutters. The authors provide numerical examples on the effect of independent variables on dependent variables, as well as examples from real-life mining and civil engineering jobs. The book assists students and engineers in machinery selection and performance prediction, and discusses rock cutting mechanics and mechanical miners.

Book excerpt: Applied Geotechnology deals with rock excavation and related topics such as the stability of soil and rock slopes, earthquakes, and earthquake engineering. Some basic ideas and fundamentals that are applicable to specific aspects of geotechnical engineering are described. 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. This monograph is written primarily for engineers and is intended as a class text for first- and second-year students of geological, mining, and civil engineering at university and technical college.
