Seller rating 4 out of 5 stars
Paperback. Condition: New. Print on Demand. This book provides a graphical analysis of coal extraction, focusing on the panel system used in mining. The author investigates the relationship between extraction percentage and various dimensions of mine workings, such as room width, length, and the number of rooms per entry. By presenting the results in tables and diagrams, the book simplifies the understanding of complex calculations involved in determining extraction efficiency. The author emphasizes the importance of increasing the ratio of room width to pillar width and extracting pillar coal to achieve higher extraction percentages. However, the book acknowledges the practical challenges and safety concerns associated with excessive pillar width reduction. Overall, this book offers valuable insights for mining engineers and professionals seeking to optimize coal extraction while maintaining safe and efficient operations. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
