Paperback. Condition: New. Print on Demand. This book delves into the science of rock blasting, a practice crucial for mining, quarrying, and tunnelling, and long used to extract materials from the earth. The author challenges conventional theories and formulas for calculating explosive charges, arguing that existing approaches often fail to account for the fundamental physics at play. He proposes a new theory, rooted in mechanical principles, that considers factors such as the shape of the blast chamber, the cohesive strength of the rock, and the weight of the rock being moved. The book explores the various resistances that a blast must overcome, including the rock's tensile and shearing strengths, the influence of gravity, and friction along fracture lines. The author meticulously outlines the conditions that determine the force of an explosion, delving into the properties of different explosives and their suitability for specific tasks. He emphasizes the importance of understanding the relationship between charge size, chamber shape, and the resistance of the rock, showing how a precise application of these principles can lead to more efficient and economical blasting operations. The book concludes with practical guidance on the safe and effective use of explosives, offering insights into the design and placement of blast holes, the selection of appropriate fuses, and the importance of proper tamping. This comprehensive and insightful treatise serves as a valuable resource for engineers, miners, quarrymen, and anyone seeking a deeper understanding of this fundamental practice. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. …

Paperback. Condition: New. Print on Demand. This book delves into the scientific principles and practical applications of rock blasting in mining, quarrying, tunneling, and other engineering projects. It challenges traditional theories and formulas, which often proved inaccurate in real-world scenarios. The author argues that previous approaches neglected crucial factors like rock cohesion, chamber shape, and the influence of gravity on the blasting process. Through meticulous experiments and analysis, the book establishes a more precise understanding of the forces at play during rock blasting. It introduces concepts such as the modulus of shearing and the chamber coefficient, providing engineers with reliable tools for calculating charges and optimizing blasting efficiency. The author emphasizes the importance of considering the specific properties of the rock, the desired outcome (e.g., shattering versus controlled breakage), and the available explosives. Detailed discussions cover various explosive types, their characteristics, and best practices for their use. Safety aspects, including tamping techniques and electric shot firing, are also thoroughly addressed. By offering a comprehensive and scientifically grounded approach to rock blasting, this book equips engineers and practitioners with the knowledge to achieve greater precision, safety, and cost-effectiveness in their operations. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
