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 exploitation Progress in Mine Safety Science and Engineering II will be invaluable to academics and engineers interested or involved in mine safety issues.
