Dynamic Analysis on Finite Element Structure of Protective Sealing Door Applied to Underground Mine Refuge Chamber
LIU Zhi-sheng
Abstract：Based on the structure dynamic response futures of the protective sealing door applied to the underground mine refuge chamber under the role of the blasting load as the study object and based on the finite element platform,a finite element model of the blasting resistance performances analysis on the protective sealed door was established and the solution and late treatment work were comple-ted.The paper analyzed the stress,deformation and air tightness condition of the protective sealing door under the role of the blasting load.The results showed that under the role of the shock wave of 0.6 MPa,the stress and deformation of the protective sealing door could meet the requirements and the air tightness was excellent,which could provide theoretical basis and data references to the further im-provement of the performances before the prototype had a blasting resistance test in the mine road-way.
