Abstract： A new protective sealing door for mine refuge chamber was designed;the theoretical analysis and experimental study on variety of rubber strips showed that the optimum compression rate of the rectangular silicone rubber sealing strip with the hardness of 20-25 degree is 15%-25% under the static sealing condition. On this basis, a sealing structure was designed according to the optimum compression amount and in consideration of some factors such as the machining error;experimental study was made on the air tightness of the protective sealing door.
