Explosion-proof performance analysis of mine refuge chamber

YANG Jun-ling1,2,MA Yue-zheng1,YANG Lu-wei1,ZHANG Zhen-tao1,3(1.Technical Institute of Physics and Chemistry of CAS,Beijing 100190,China;2.Graduate University of CAS,Beijing 100049,China;3.Institute of Coal of Xinjiang Uygur Autonomous Region,Urumqi 830019,China)  
The stress,strain and energy of a coal mine refuge chamber under explosion load were analyzed.The results demonstrate that the structure of No.5 channel welding 10 mm shell can resist the explosion load of 0.6 MPa amplitude.The displacement of the front panel of the chamber increasies with the explosion load.Maximum of displacement of the panel is 1.47 mm when the explosion load amplitude is 0.6 MPa.While the load is moved,the displacement decreases slowly and the regulation adapts to internal energy,kinetic energy and strain energy of the whole model.
