Abstract: As for the strength check explosion experiment limitations of refuge chamber such as the complicated procedure, difficult result assessment and high co sts, the paper puts forward a FEM simulation method, which was to analyze the dynamic respond of the chamber parts under gas explosion on the basis of flow field loa d, resulted from the stimulation of gas explosion in the roadway by two soft wares of AUTODYN and LS-DYNA being approved by National Mine Product Safety Certifica te Center. The analysis results showed that the structure of the existing KJYF-96 /8 refuge chamber kept integral against the front blasting pressure of 0.6 MPa and its key parts were undamaged, which was in accordance with the national regulation. By this way, the weakness of key parts for the refuge chamber could be found out an d calculated to save research time and costs.
