Paperback. Condizione: New. Print on Demand. This book illuminates the ignition of mine gases by the filaments of incandescent lamps. Following an investigation into the causes of mine accidents, the author meticulously evaluates the degree of danger posed by using specific sizes of incandescent lamps in atmospheres containing flammable gas. The research detailed in this book reveals which lamp sizes and circumstances are most likely to ignite gas and provides practical guidance for mitigating risks in underground mining operations. The findings offer critical insights into the prevention of mine explosions and the preservation of safety for miners. 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. Condizione: New. Print on Demand. This book details the development of electric mine lamps from their earliest forms to the highly practical devices used in mines today. The author traces the evolution of these lamps as they sought to replace the hazardous open-flame lamps of the time, which posed significant risks of causing explosions or fires in the presence of flammable gases found in mines. The author describes the challenges faced by early lamp designers, including preventing gas ignition, minimizing unexpected lamp extinction, and improving light production. The book also discusses the development of the necessary safety features, such as bulb-extinguishing devices and non-spilling battery designs, to meet the safety requirements of the Bureau of Mines. The volume serves as a valuable resource for understanding the historical development and technical advancements in electric mine lamps, which have significantly improved the safety and efficiency of mining operations.
