Structural Design and Optimization of the Blast-resistant and Waterproof Refuge Chamber Cabin in Underground Mine

Abstract

To ameliorate the situation that the normal mine refuge chamber cabin’s emergency exit is quite unitary and unable to open the door when flooding accident occurred, a new type of refuge chamber cabin was designed. The new cabin has emergency escape hatches in the side and on the top of the life-support compartment. Then the use of ANSYS/LS-DYNA to simulate and analyze the stress and strain distribution of the chamber cabin was presented. Considering the antiknock performance and the cost of the cabin, local and overall optimization of the cabin’s structure were carried out. Different optimization schemes were analyzed to get a refuge chamber cabin with higher cost-effectiveness, which can provide a theoretical reference for the underground refuge chamber’s design.
