Rockburst in Extra-Thick Coal Seam Mining: Mechanism and Prevention

This book provides a detailed introduction to the mechanism of rockburst in extremely thick coal seam mining and explores the mechanical mechanism on why the critical depth of rockburst in extremely thick coal seam mining is significantly smaller than that in thin to thick coal seams, it also proposes targeted monitoring, warning, and treatment technologies. The prevention and control of coal mine rockburst is a global problem, attracting engineers and scientists from various disciplines such as mining, geology, geophysics, and civil engineering to conduct research. This book provides multiple case studies of rockburst accidents in mining of ultra-thick coal seams and provides a detailed analysis of the mechanisms and treatment technologies of each rockburst accident. It aims at graduate students, researchers, and on-site engineers who are interested in the mechanism of rockburst occurrence, monitoring, early warning, and treatment technology.
