As societies continue to grow and develop, the demand for energy has increased worldwide. In China, coal is still one of the principal energy resources and it is expected that more coal mining projects are needed in the future. As mining operations continue to increase their production rates and discover more ore reserves, mine safety issues have become more urgent. Even more than in the past there is a greater need to understand these issues better. Progress in Mine Safety Science and Engineering II discusses mine safety techniques and technologies, methods and approaches, as well as problems and issues. The contributions cover a wide range of topics:• Coal mine safety• Metal and non-metal mine safety• Mine product testing technology and safety symbol management• Mine rescue tools and techniques• Mine safety management and standardization• Mine safety science and theory• Occupational health and safety in mines• Petroleum and natural gas exploitationProgress in Mine Safety Science and Engineering II will be invaluable to academics and engineers interested or involved in mine safety issues.

This book investigates the evolution process of rockburst based on the energy dissipation theory and proposes appropriate active prevention and control technologies. It discusses the electromagnetic radiation (EMR) generated by coal rock fractures as a measurement of the amount of dissipated energy, and the use of EMR to experimentally observe the time domain characteristics of energy dissipation during coal rock failure processes. It then proposes the concept of the rockburst activity domain system (RADS), establishes a dynamic pressure model of rockburst, and describes the energy criterion for rockburst instability. Lastly, it presents two waterjet cutting-based cases of pressure relief and rockburst prevention. The book serves as a reference resource for mine safety workers, engineering technicians, scientists, graduate students and undergraduates engaged in research on dynamic hazards such as rockburst..
