In order to ensure the research and development production of coal mine "KJYF - 96/8 portable hardware capsule" in the coal mine use can effectively resist gas explosion shock pressure, structural strength meet the safety requirements. The finite element model is set up, to take specific gas coal dust explosion triangle under the action of shock waves, the stress, strain and displacement response. The results show that the peak of 0.6 MPa and 1.2 MPa, 300ms triangle shock wave, the capsule basic no plastic deformation, overall no failure parts, ships were able to be whole, the structure safety. Depending on the overall displacement nephogram view of displacement nephogram and components parts after shock wave action, maintain the overall coordination deformation, minimal relative displacement, sealing well.
