Study on Numerical Simulation and Bolt Grouting Mechanism of Mine Fracture Rock Masses
Abstract：The constitutive relation such as shear strength and optimal anchoring angle of jointed rock masses are obtained by analyzing the bolt grouting mechanism of mine joint fissure rock masses.The rock roadway of highly-jointed double-track roadway is simulated respectively by FLAC3D software under the condition of no-support and bolting and grouting.The simulation results show that the support with bolting and grouting enhances the bearing capacity of jointed roadway,improves the stress station,and limits the deformation of the jointed roadway rock.
