Probing into Design of refuge chamber system in coal mine

Put forward the refuge chamber system composed by permanent refuge chamber, temporary refuge chamber and rescue capsule, which are mutually independent and tightly-coupled, to cost-effectively radiate all the areas with mining activities and protect personnel in mine. In addition, in order to promote the development of refuge chamber system in Chinese coal mine, propose some basically design principles of refuge chamber system and describe the arrangement principles and structure characteristics of three kinds of refuge space in the process of underground refuge chamber system design and construction. It is a significant reference for coal mine refuge chamber system construction in China. (C) 2010 Published by Elsevier Ltd.
