Numerical Simulation Analysis of Bolt Supporting Function Under High Horizontal Stress
Roadway bolt supporting, which relates the equations such as ground stress, mechanical property of surrounding rock and bolt supporting structure, is an engineering problem of rock and structure coupling. Three-dimensional development entry bolt supporting aided design system was developed by using ANSYS finite element software. Supporting function mechanics of coal roadway bolt supporting was analyzed and calculated under high horizontal stress. The effects of bolt supporting under similar conditions on strata separating, roadway deformation, stress and displacement field around the roadway was mainly studied. The action rules of bolt supporting at given condition were analyzed. Several significant conclusions guiding production were put forward.
