Structural Analysis and Study on Support Technology of Refuge Chamber of Mine

Abstract:

As the down-hole refuge chamber is the last life support for miners, its stability structure is especially important in its design. This paper tested the loose circle of the surrounding rock of refuge chamber with double-hole method, proposed the related parameters of chamber support, and conducted numerical analysis for the deformation, damage and supporting effect of the surrounding rock by using FLAC. The result shows: the loose circle radius of this refuge chamber is about 1.7~2.0m；the surrounding rock of refuge room belongs to IV class with large loose circle, designs support parameters with anchor net spray built-up arch theory; the numerical analysis shows that the floor suffers from floor heave, so it needs to be set up with anti-arch structure and be filled with reinforcement material.
