Numerical Simulation Analysis of The NanYangpo Coal Mine Anchor Support Method
The bolt support is important to ensure the stability of surrounding rock.Of Nan Yangpo mines as the research background.The application of numerical simulation software FLAC3D mine deep Bolt bolt support after the surrounding rock deformation law of the numerical simulation,Comparison and analysis of rock displacement and plastic zone under the support program changes.The results show that,The third bolt support nursing program,Significantly improve the strength and load carrying capacity of the surrounding rock,Effectively control the damage of the deep tunnel deformation that can control the roof of 4101 the return airway and two to help the stability.
