Abstract：The blast front is a key part of the refuge chamber, it will bear large shock load and the chamber's door will be located on it. Based on HyperWoks and AUTODYN, numerical simulation and analysis were carried out on the refuge chambers with different blast front structure. For the chamber with different blast front convex structure under the shock of the same blast source, when the distance of arc-shaped convex increased from 0 to 1 200 mm, the maximum displacement of the blast front unit decreased exponentially from 19 mm to 0. 09 mm. This research result can provide reference basis for the structure design, optimization and the antiknock performance improvement of the refuge chamber.
