Meticulous study on each component of the bolting support system plays an important role in assuring scientific and secure support for the mine roadways.For further understanding the influence of arch structure on steel pallet's mechanical property, and its beating applicability when matching with different bolts, bearing capacity and deformation characteristics of square pallets with different thickness and different arch height were investigated by using laboratory loading tests;experiment results well verified the correctness of the theoretical relationship, which also was shown, The size and strength of adjustable ball-pad played an important role for complete bearing capacity of arched pallet.Simulation tests of FEM were employed to predict load-displacement and stress distribution feature of different arched pallet area.At last, based on the previous studies, arch structure calculation and the coal industry standard, a reasonable reference table was proposed for matching different bolts specification and ordinary arched pallets' size, which can be used in mines support engineering.
