Research on Performance of Coal Mine Refuge …

The coal mine refuge chamber is the necessary production of emergency system used in the underground coal mine. It can be installed conveniently and moved with the workplace. So it is more widely applied. The composition and basic performance requirements of coal mine refuge chamber were introduced in this paper. The performance of reinforcing ribs was done by finite element analysis …

Buckling Capacity Optimization of Coal Mine Refuge …

The cylindrical shell with rectangle stiffeners was usually utilized in coal mine refuge chambers. Aiming at the buckling deformation of thin cylindrical shell under uniform axial compression, finite element analysis software ANSYS was employed to set up the optimization model of stiffened cylindrical shell, and the sequential linear programming method was executed to optimize the thickness of ...

 · Mine refuge chambers are used to shield miners who fail to escape from the mine when incidents occur. Environment maintaining system plays a key role in stabilizing thermal environment of a mine refuge chamber against heat emitted from metabolism and transferred from outside. The safety and comfort of refugees are closely related to the environment maintaining system design.

A stiffened cylindrical shell is normally used in refuge chambers of a coal mine. Based on the method of application and shape characteristics of a refuge chamber, we simplified its shell as an orthotropic cylinder. The basic buckling equation of the stiffened cylindrical shell under uniform axial compression was deduced by using a Donnell ...
