Numerical Simulation and Engineering Application of Bolts Supporting in a Coal Roadway in Tectonic Stress Field
Roadway bolt supporting, which relates the equations such as ground stress, mechanical property of surrounding rock and bolt structure, is an engineering problem of rock and structure coupling. Three-dimensional developing entry bolt supporting aided design system is developed by using ANSYS. Supporting function mechanics of coal roadway bolt supporting is analyzed and calculated. The effects of bolt supporting under similar conditions on roadway deformation, stress and displacement field around the roadway are mainly studied. The simulation results are applied in bolt supporting engineering of a coal mine 2395 coal roadway, and excellent supporting results are obtained which provides good experience for further generalization and application.
