Abstract: Aiming at the production technology condition of Tangkou Coal Mine, from the aspect of improving coal mine safety assurance ability, the emergency refuge system was designed in Tangkou Coal Mine, it was composed of permanent refuge chamber, temporary refuge chamber and moveable capsule. In the design and construction process of emergency refuge system, some issues should be taken into full account, for example the mining continuation plan, the surrounding rock and ground pressure, as well as the safety production condition. At the same time, the system should combine with oxygen supply subsystem and environmental monitoring system effectively. The application of emergency refuge system could enhance the safety of the workers in underground coal mine, and guarantee the safe operation of coal mine enterprise.
