Features: The dynamic disaster phenomena occurring in porous media such as coal, rock, and concrete mainly include coal and gas outbursts, rock bursts, roof falls, landslides, tunnel and dam foundation instability, etc. Based on a large number of laboratory and field experiments, this book combines theoretical research from multiple disciplines such as rheology, physicochemistry, and electromagnetic dynamics. It preliminarily establishes and systematically discusses the rheological mechanisms and electromagnetic radiation energy release patterns in the occurrence process of coal and rock dynamic disasters. It reveals the relationship between the rheological failure process and electromagnetic radiation information in porous media such as coal and rock under different pore fluid conditions, establishes and conducts numerical simulations of the coal and rock force-electric coupled field; analyzes the experimental and theoretical regularities of electromagnetic radiation memory effects; systematically explores the mechanisms of electromagnetic radiation generated during coal and rock fracturing; preliminarily investigates the action patterns of external electromagnetic fields on adsorbed gases; establishes and systematically discusses the theory and technology of non-contact monitoring and prediction of coal and rock dynamic disasters based on the electromagnetic radiation theory of coal and rock rheological failure, invents monitoring equipment; and introduces the experimental systems, information processing technology, and application cases of electromagnetic radiation monitoring during coal and rock failure. This book is available for reference for scientists, graduate and undergraduate students, and technical personnel working in fields such as coal and rock, concrete dynamic disaster phenomena (coal and gas outbursts, rock bursts, landslides, roof falls, tunnel and dam foundation instability, earthquakes, etc.), the mechanical behavior of porous coal and rock, and geotechnical engineering.
