Design and Antiknock Impact Performance Analysis of New Mine Refuge Chamber Cabin of Waterproof and Antitoxic

Abstract:

The emergency escape hatches of refuge cabin are usually installed in both sides of the life supporting compartment, which might cause the toxic gases or water enter into life supporting compartment when the gas explosion and water inrush accident occur. A new type of refuge cabin structure that can effectively resist the toxic gases and water entering the life supporting compartment is developed in this paper. Numerical simulation of antiknock impact performance of the new refuge cabin was calculated and analyzed by using the finite element software of LS-DYNA.The stress and strain distributions and maximum antiknock performance were obtained. Refuge chamber cabin has been optimized to reduce cost. The antiknock impact performance of optimized mine refuge chamber cabin can reach 1.4MPa which is greater than the 0.6MPa of standard value and the cost can be reduced approximate 19% than the original model.
