Abstract
In order to improve the safety and reliability, and reduce development costs of the refuge chamber cabin, we combined TNT equivalent substitute with numerical simulation method, used software AUTODYN to carry on simulation calculation and obtain coal mine gas blast law and determine explosion shock loading. On this basis, four different refuge chamber cabin structure geometries based on stiffeners were designed , then the ANSYS Workbench platform software was used to perform dynamic simulation and safety comparative analysis for anti-knock properties of four different stiffeners refuge chambers, we obtained a mine refuge chamber structure with low-cost and good performance, which provided some ideas for mine refuge chamber’s research and development.
