Abstract:
The rock bolt plates is one of the important components constituting the bolt structure. The paper uses numerical method . to build the model with the mesh size (length xwidth*height=6x0.6x4 m), install a bolt in the middle of the model with the size of the plates .is 150x150 mm. Studies the effect width and thickness of the square plates to the stress distribution and the deformation in plates. This results show that the influence of the dimensions of plates to tangential stress distribution and tangential deformation in the plates, also from the research results help for designing, constructing company have the basis for selection dimensions of rock bolt plates.
