Mechanisms of rockbolt support for highly fractured rock masses–insight from physical and numerical modeling
https://orcid.org/0000-0001-6530-9787
Abstract Rockbolting is the most common support system in both civil and mining engineering. The mechanics of ground support using rockbolt have yet not been very clear, especially in highly fractured rock mass conditions. In this study, large-scale physical models with full-scale rockbolts and rock blocks were constructed, aiming to evaluate the bearing capacity of incoherent rock blocks quantitatively. The effect of surface support was especially examined with the incorporation of different sizes of bearing plates and mesh in the models. It is found that lateral confinement plays an important role in the load bearing and deformation capacity of the incoherent rock blocks reinforced by rockbolts. High lateral confinement promotes the formation of a strong pressure arch. The installation of surface support can significantly increase the deformation capacity of incoherent rock blocks. The result provides insight into the mechanism of rockbolting and highlights the importance of surface support in highly fractured rock mass ground conditions.
