Abstract

Abstract: In view of poor impart resistance ability and failure due to damage in rockburst of the anti-scour and supporting equipment, the paper was aimed at developing a new kind of anti-scour and supporting device with great energy absorption performance .After numerical simulation of ordinary square tube axial compression, a pre-folded edge tube anti-scour and supporting device was designed and its energy absorption performance was studied by carrying out a finite element simulation. The effect of the plate inclination angle on the performance was studied. An energy absorption performance comparison was made between the pre-folded edge tube and the square tube. Finally, the best plate inclination angle of pre-folded edge tube anti-scour and supporting device was verified by carrying laboratory experiments. The results show that the pre-folded edge tube anti-scour and supporting device has the best energy absorption perormance.

Key words: rockburst, anti-scour and supporting device, energy absorption structure, energy absorption performance, plate inclination angle
