Thick Coal Seam Underground Mining

This book systematically summarizes the main technology and latest advancements of China's thick coal seam underground mining technology. It covers the mine development methods, the top coal caving technology and drawing mechanism, the measurement of top coal recovery and technology to improve the recovery ratio, the large mining height technology and coal wall stability control, large cross-section roadway support technology, slicing mining technology and roadway layout, intelligent mining technology and advancements, theories and techniques for controlling surrounding rock in thick coal seam, as well as some typical cases of top coal caving and large mining height. This book can serve as a teaching reference for graduate students in mining engineering and senior undergraduate students at higher education institutions. It is also suitable for researchers, engineering technicians, designers, and relevant technology management personnel engaged in coal mining.

Summarizes advanced technology in top coal mining, large mining height mining, and slice mining Reviews the latest research in the field of intelligent mining of thick coal seam in China Lists the history and technical application of thick coal seam mining in several large mining zones in China
